#################################################################################
# Sample platypush configuration file.
# Edit it and copy it to /etc/platypush/config.yaml for system installation or to
# ~/.config/platypush/config.yaml for user installation (recommended).
#################################################################################
# --
# include directive example
# --
#
# You can split your configuration over multiple files
# and use the include directive to import them in your configuration.
# Relative paths are also supported, and computed using the config.yaml
# installation directory as base folder. Symlinks are also supported.
#
# Using multiple files is encouraged in the case of large configurations
# that can easily end up in a messy config.yaml file, as they help you
# keep your configuration more organized.
#include:
# - include/logging.yaml
# - include/media.yaml
# - include/sensors.yaml
# platypush logs on stdout by default. You can use the logging section to specify
# an alternative file or change the logging level.
#logging:
# filename: ~/.local/log/platypush/platypush.log
# level: INFO
# The device_id is used by many components of platypush and it should uniquely
# identify a device in your network. If nothing is specified then the hostname
# will be used.
#device_id: my_device

## Plugin configuration examples
## --
#
# Plugins configuration is very straightforward. Each plugin is mapped to
# a plugin class. The methods of the class with @action annotation will
# be exported as runnable actions, while the __init__ parameters are
# configuration attributes that you can initialize in your config.yaml.
# Plugin classes are documented at https://docs.platypush.tech/en/latest/plugins.html
#
# In this example we'll configure the light.hue plugin, see
# https://docs.platypush.tech/en/latest/platypush/plugins/light.hue.html
# for reference. You can easily install the required dependencies for the plugin through
# pip install 'platypush[hue]'
light.hue:
# IP address or hostname of the Hue bridge
bridge: 192.168.1.10
# Groups that will be handled by default if nothing is specified on the request
groups:
- Living Room
# Example configuration of music.mpd plugin, see
# https://docs.platypush.tech/en/latest/platypush/plugins/music.mpd.html
# You can easily install the dependencies through pip install 'platypush[mpd]'
music.mpd:
host: localhost
port: 6600
# Example configuration of media.chromecast plugin, see
# https://docs.platypush.tech/en/latest/platypush/plugins/media.chromecast.html
# You can easily install the dependencies through pip install 'platypush[chromecast]'
media.chromecast:
chromecast: Living Room TV
# Plugins with empty configuration can also be explicitly enabled by specifying
# enabled=True or disabled=False (it's a good practice if you want the
# corresponding web panel to be enabled, if available)
camera.pi:
enabled: True
# Support for calendars - in this case Google and Facebook calendars
# Installing the dependencies: pip install 'platypush[ical,google]'
calendar:
calendars:
- type: platypush.plugins.google.calendar.GoogleCalendarPlugin

## Backends configuration examples
## --
#
# Backends are basically threads that run in the background and listen for something
# to happen and either trigger events or provide additional services on top of platypush.
# Just like plugins, backends are classes whose configuration matches one-to-one the
# supported parameters on the __init__ methods. You can check the documentation for the
# available backends here: https://docs.platypush.tech/en/latest/backends.html.
# Moreover, most of the backends will generate events that you can react to through custom
# event hooks. Check here for the events documentation:
# https://docs.platypush.tech/en/latest/events.html
#
# You may usually want to enable the HTTP backend, as it provides many useful features on
# top of platypush. Among those:
#
# - Expose the /execute endpoint, that allows you to send requests to platypush through a
# JSON-RPC interface.
# - Web panel, one of the key additiona features of platypush. Many plugins will expose web
# panel tabs for e.g. accessing and controlling lights, music, media and sensors.
# - Dashboard: platypush can be configured to show a custom dashboard on your screens with
# e.g. music platypush and weather info, news, upcoming calendar events and photo carousel.
# - Streaming support - the HTTP backend makes it possible to stream local media to other
# devices - e.g. Chromecasts and external browsers.
#
# To install the HTTP backend dependencies simply run 'pip install "platypush[http]"'
backend.http:
# Listening port
port: 8008
# Through resource_dirs you can specify external folders whose content can be accessed on
# the web server through a custom URL. In the case below we have a Dropbox folder containing
# our pictures and we mount it to the '/carousel' endpoint.
resource_dirs:
carousel: /mnt/hd/photos/carousel
# The HTTP poll backend is a versatile backend that can monitor for HTTP-based resources and
# trigger events whenever new entries are available. In the example below we show how to use
# the backend to listen for changes on a set of RSS feeds. New content will be stored by default
# on a SQLite database under ~/.local/share/platypush/feeds/rss.db.
# Install the required dependencies through 'pip install "platypush[rss,db]"'
backend.http.poll:

- type: platypush.backend.http.request.rss.RssUpdates # HTTP poll type (RSS)
# Remote URL

## Assistant configuration examples
## --
#
# Both Google Assistant and Alexa voice assistant interfaces are supported by platypush.
# You can easily make your custom voice assistant with a RaspberryPi and a USB microphone,
# or on your laptop. Note however that the Alexa integration is still experimental
# (mostly because of glitches and bugs on the avs package provided by Amazon), while the
# Google Assistant support should be more robust. The recommended way of triggering a
# hotword ('OK Google', 'Alexa' or any custom hotword you like) is through the snowboy
# backend (install it through 'pip install "platypush[hotword]"'). You can download custom
# voice model files (.umdl) from https://snowboy.kitt.ai.
backend.assistant.snowboy:
# Microphone audio gain
audio_gain: 1.1
models:
# "Computer" hotword model
computer:
# UMDL file path
voice_model_file: ~/.local/share/snowboy/models/computer.umdl
# Plugin to use (Google Assistant)

# Language assistant (Italian)

## Procedure examples
## --
#
# Procedures are lists of actions that can be executed synchronously (default) or in parallel
# (procedure.async. prefix). Basic flow control operators (if/else/for) are also available.
# You can also access Python variables and evaluate Python expressions by using the ${} expressions.
# The 'context' special variable is a name->value dictionary containing the items returned from
# previous actions - for example if an action returned '{"status": "ok", "temperature":21.5}' then
# the following actions can access those variables through ${status} and ${temperature} respectively,
# and you can also add things like '- if ${temperature > 20.0}' or '- for ${temp in temperature_values}'.
# Alternatively, you can access those variable also through ${context.get('status')} or ${context.get('temperature')}.
# Other special variables that you can use in your procedures:
#
# - output: Will contain the parsed output of the previous action
# - errors: Will contain the errors of the previous action
# - event: If the procedure is executed within an event hook, it contains the event that triggered the hook
#
# An example procedure that can be called when you arrive home. You can run this procedure by sending a JSON
# message like this on whichever backend you like (HTTP, websocket, TCP, Redis, MQTT, Node-RED, Pushbullet...)
# {"type":"request", "action":"procedure.at_home"}
# You can for instance install Tasker+AutoLocation on your mobile and send this message whenever you enter
# your home area.
procedure.at_home:
# Set the db variable HOME to 1
- action: variable.set
args:
HOME: 1
# Check the luminosity level from a connected LTR559 sensor
- action: gpio.sensor.ltr559.get_data
# If it's below a certain threshold turn on the lights
- if ${int(light or 0) < 110}:
- action: light.hue.on
# Say a welcome home message. Install dependencies through 'pip install "platypush[google-tts]"'
- action: tts.google.say
args:
text: Welcome home
# Start the music
- action: music.mpd.play
# Procedure that will be execute when you're outside of home
procedure.outside_home:
# Unset the db variable HOME
- action: variable.unset
args:
name: HOME
# Stop the music
- action: music.mpd.stop
# Turn off the lights
- action: light.hue.off
# Start the camera streaming. Install the Pi Camera dependencies through
# 'pip install "platypush[picamera]"'
- action: camera.pi.start_streaming
args:
listen_port: 2222
# Procedures can also take optional arguments. The example below show a
# generic procedure to send a request to another platypush host over MQTT
# given target, action and args
procedure.send_request(target, action, args):
- action: mqtt.send_message
args:
topic: platypush_bus_mq/${target}
host: mqtt-server
port: 1883
msg:
type: request
target: ${target}
action: ${action}
args: ${args}
## --
## Event hook examples
## --
#
# Event hooks are procedures that are run when a certain condition is met.
# Check the documentation of the backends to see which events they can trigger.
# An event hook consists of two parts: an 'if' field that specifies on which
# event the hook will be triggered (type and attributes content), and a 'then'
# field that uses the same syntax as procedures to specify a list of actions to
# execute when the event is matched.
#
# The example below plays the music on mpd/mopidy when your voice assistant
# triggers a speech recognized event with "play the music" content.
event.hook.PlayMusicAssistantCommand:
if:
type: platypush.message.event.assistant.SpeechRecognizedEvent
# Note that basic regexes are supported, so the hook will be triggered
# both if you say "play the music" and "play music"
phrase: "play (the)? music"
then:
- action: music.mpd.play
# This will turn on the lights when you say "turn on the lights"
event.hook.TurnOnLightsCommand:
if:
type: platypush.message.event.assistant.SpeechRecognizedEvent
phrase: "turn on (the)? lights?"
then:
- action: light.hue.on
# This will play a song by a specified artist
event.hook.SearchSongVoiceCommand:
if:
type: platypush.message.event.assistant.SpeechRecognizedEvent
# Note that you can use the ${} operator in event matching to
# extract part of the matched string into context variables that
# can be accessed in your event hook.
phrase: "play ${title} by ${artist}"
then:
- action: music.mpd.clear
- action: music.mpd.search
args:
filter:
artist: ${artist}
title: ${title}
# Play the first search result
- action: music.mpd.play
args:
resource: ${output[0]['file']}
# This event will scrobble newly listened tracks on mpd/mopidy to last.fm
event.hook.ScrobbleNewTrack:
if:
type: platypush.message.event.music.NewPlayingTrackEvent
then:
- action: lastfm.scrobble
args:
artist: ${track['artist']}
title: ${track['title']}
- action: lastfm.update_now_playing
args:
artist: ${track['artist']}
title: ${track['title']}
## --
## Cron examples
## --
#
# Cronjobs allow you to execute procedures at periodic intervals.
# Standard UNIX cron syntax is supported, plus an optional 6th indicator
# at the end of the expression to run jobs with second granularity.
# The example below executes a script at intervals of 1 minute.
cron.TestCron:
cron_expression: '* * * * *'
actions:
- action: shell.exec
args:
cmd: ~/bin/myscript.sh

################################################################################
# Sample Platypush configuration file.
#
# Edit it and:
# - Copy it to /etc/platypush/config.yaml for system installation.
# - Copy it to ~/.config/platypush/config.yaml for user installation.
# - Start the application with `-c <path-to-this-file>`.
#
# Since the configuration file also includes the custom integrations, you can
# create a Platypush custom installation, with all the extra dependencies
# required by the configured integrations, using the `platydock` or `platyvenv`
# commands and passing this file as an argument. These commands will build a
# Docker image or a Python virtual environment respectively, with all the
# required extra dependencies inferred from your configuration file.
#
# A `scripts` directory with an empty `__init__.py` script will also be created
# under the same directory as the configuration file. This directory can be
# used to add custom scripts containing procedures, hooks and crons if you want
# a full Python interface to define your logic rather than a YAML file.
#
# Please refer to the `scripts` directory provided under this file's directory
# for some examples that use the Python API.
################################################################################
### ------------------
### Include directives
### ------------------
# # You can split your configuration over multiple files and use the include
# # directive to import other files into your configuration.
#
# # Files referenced via relative paths will be searched in the directory of
# # the configuration file that references them. Symbolic links are also
# # supported.
#
# include:
# - logging.yaml
# - media.yaml
# - sensors.yaml
### -----------------
### Working directory
### -----------------
# # Working directory of the application. This is where the main database will be
# # stored by default (if the default SQLite configuration is used), and it's
# # where the integrations will store their state.
#
# # Note that the working directory can also be specified at runtime using the
# # -w/--workdir option.
# #
# # If not specified, then one of the following will be used:
# #
# # - $XDG_DATA_HOME/platypush if the XDG_DATA_HOME environment variable is set.
# # - $HOME/.local/share/platypush otherwise.
#
# workdir: ~/.local/share/platypush
### ----------------------
### Database configuration
### ----------------------
# # By default Platypush will use a SQLite database named `main.db` under the
# # `workdir`. You can specify any other engine string here - the application has
# # been tested against SQLite, Postgres and MariaDB/MySQL >= 8.
# #
# # NOTE: If you want to use a DBMS other than SQLite, then you will also need to
# # ensure that a compatible Python driver is installed on the system where
# # Platypush is running. For example, Postgres will require the Python pg8000,
# # psycopg or another compatible driver.
#
# main.db:
# engine: sqlite:///home/user/.local/share/platypush/main.db
# # OR, if you want to use e.g. Postgres with the pg8000 driver:
# engine: postgresql+pg8000://dbuser:dbpass@dbhost/dbname
### ---------------------
### Logging configuration
### ---------------------
# # Platypush logs on stdout by default. You can use the logging section to
# # specify an alternative file or change the logging level.
#
# # Note that a custom logging directory can also be specified at runtime using
# # the -l/--logsdir option.
#
# logging:
# filename: ~/.local/log/platypush/platypush.log
# level: INFO
### -----------------------
### device_id configuration
### -----------------------
# # The device_id is used by many components of Platypush and it should uniquely
# # identify a device in your network. If nothing is specified then the hostname
# # will be used.
#
# # Note that a custom device ID can also be specified at runtime using the
# # -d/--device-id option.
#
# device_id: my_device
### -------------------
### Redis configuration
### -------------------
# # Platypush needs a Redis instance for inter-process communication.
# #
# # By default, the application will try and connect to a Redis server listening
# # on localhost:6379.
# #
# # Platypush can also start the service on the fly if instructed to do so
# # through the `--start-redis` option. You can also specify a custom port
# # through the `--redis-port` option.
# #
# # If you are running Platypush in a Docker image built through Platydock, then
# # `--start-redis` is the default behaviour and you won't need any extra
# # documentation here.
#
# redis:
# host: localhost
# port: 6379
# username: user
# password: secret
### ------------------------
### Web server configuration
### ------------------------
# Platypush comes with a versatile Web server that is used to:
#
# - Serve the main UI and the UIs for the plugins that provide one.
# - Serve custom user-configured dashboards.
# - Expose the `/execute` RPC endpoint to send synchronous requests.
# - Expose the `/ws/events` and `/ws/requests` Websocket paths, which can be
# respectively by other clients to subscribe to the application's events or
# send asynchronous requests.
# - Stream media files provided by other plugins, as well as camera and audio
# feeds.
# - Serve custom directories of static files that can be accessed by other
# clients.
# - Provide a versatile API for hooks - the user can easily create custom HTTP
# hooks by creating a hook with their custom logic that reacts when a
# `platypush.message.event.http.hook.WebhookEvent` is received. The `hook`
# parameter of the event specifies which URL will be served by the hook.
#
# The Web server is enabled by default, but you can disable it simply by
# commenting/removing the `backend.http` section. The default listen port is
# 8008.
#
# After starting the application, you can access the UI at
# http://localhost:8008, set up your username and password, and also create an
# access or session token from the configuration panel.
#
# This token can be used to authenticate calls to the available APIs.
# For example, to turn on the lights using the /execute endpoint:
#
# curl -XPOST -H "Authorization: Bearer $TOKEN" \
# -H "Content-Type: application/json" \
# -d '
# {
# "type": "request",
# "action": "light.hue.on",
# "args": {
# "lights": ["Bedroom"]
# }
# }' http://localhost:8008/execute
#
# If you want to serve the Web server behind a reverse proxy, you can copy the
# reference configuration available at
# https://git.platypush.tech/platypush/platypush/src/branch/master/examples/nginx/nginx.sample.conf
backend.http:
# # Bind address (default: 0.0.0.0)
# bind_address: 0.0.0.0
# # Listen port (default: 8008)
port: 8008
# # resource_dirs can be used to specify directories on the host system that
# # you want to expose through the Web server. For example, you may want to
# # expose directories that contain photos or images if you want to make a
# # carousel dashboard, or a directory containing some files that you want to
# # share with someone (or other systems) using a simple Web server.
# #
# # In the following example, we're exposing a directory with photos on an

### Plugin configuration examples
### -----------------------------
###
# # The configuration of a plugin matches one-to-one the parameters required by
# # its constructor.
# #
# # Plugin classes are documented at https://docs.platypush.tech/en/latest/plugins.html
# #
# # For example, there is a `light.hue` plugin
# # (https://docs.platypush.tech/platypush/plugins/light.hue.html) whose
# # constructor takes the following parameters: `bridge`, `lights` (default
# # target lights for the commands), `groups` (default target groups for the
# # commands) and `poll_interval` (how often the plugin should poll for updates).
# #
# # This means that the `light.hue` plugin can be configured here as:
#
# light.hue:
# # IP address or hostname of the Hue bridge
# # NOTE: The first run will require you to register the application with
# # your bridge - that's usually done by pressing a physical button on your
# # bridge while the application is pairing.
# bridge: 192.168.1.3
# # Groups that will be handled by default if nothing is specified on the request
# groups:
# - Living Room
#
# # How often we should poll for updates (default: 20 seconds)
# poll_interval: 20
###
###
# # Example configuration of music.mpd plugin, a plugin to interact with MPD and
# # Mopidy music server instances. See
# # https://docs.platypush.tech/en/latest/platypush/plugins/music.mpd.html
# # You can easily install the dependencies through pip install 'platypush[mpd]'
#
# music.mpd:
# host: localhost
# port: 6600
###
###
# # Plugins with empty configuration can also be explicitly enabled by specifying
# # `enabled: true` or `disabled: false`. An integration with no items will be
# # enabled with no configuration.

###
###
# # Enable the system plugin if you want your device to periodically report
# # system statistics (CPU load, disk usage, memory usage etc.)
# #
# # When new data is gathered, an `EntityUpdateEvent` with `plugin='system'` will
# # be triggered with the new data, and you can subscribe a hook to these events
# # to run your custom logic.

### --------------------
### Camera configuration
### --------------------
###
# # There are several providers for the camera integration - you can choose
# # between ffmpeg, gstreamer, PiCamera etc., and they all expose the same
# # interface/configuration options.
# #
# # It is advised to use the ffmpeg integration, as it's the one that provides
# # the highest degree of features and supported hardware.
# #
# # If the plugin is correctly configured, you can access your camera feed from
# # the Platypush Web panel, programmatically start/stop recording sessions, take
# # photos, get a feed stream URL etc.
#
# # The camera feed will be available at `/camera/<plugin>/video[.extension]`,
# # for example `/camera/ffmpeg/video.mjpeg` for MJPEG (usually faster), or
# # `camera/ffmpeg/video.mp4` for MP4.
#
# # You can also capture images by connecting to the
# # `/camera/<plugin>/photo[.extension]`, for example `/camera/ffmpeg/photo.jpg`.
#
# camera.ffmpeg:
# # Default video device to use
# device: /dev/video0
# # Default resolution
# resolution:
# - 640
# - 480
# # The directory that will be used to store captured frames/images
# frames_dir: ~/Camera/Photos
# # Default image scaling factors (default: 1, no scaling)
# scale_x: 1.5
# scale_y: 1.5
# # Default rotation of the image, in degrees (default: 0, no rotation)
# rotate: 90
# # Grayscale mode (default: False):
# grayscale: false
# # Default frames per second (default: 16)
# fps: 16
# # Whether to flip the image along the horizontal axis (default: False)
# horizontal_flip: false
# # Whether to flip the image along the horizontal axis (default: False)
# vertical_flip: false
###

### Sound integration
### -----------------
###
# # The sound plugin allows you to stream from an audio source connected to the
# # machine, play audio files or synthetic audio waves or MIDI sounds.
#
# # After enabling the plugin, you can access the audio stream at
# # `/sound/stream[.extension]` (e.g. `/sound/stream.mp3`) if you want to get a
# # live recording of the captured sound from the configured audio
# # `input_device`.
#
# sound:
# enabled: true

### Some examples of media integrations
### -----------------------------------
###
# # Example configuration for the media.vlc plugin. You can replace `vlc` with
# # `mpv`, `mplayer`, `omxplayer` or `gstreamer` if you want to use another
# # player - the supported configuration option are the same across all these
# # players.
#
# media.vlc:
# # Volume level, between 0 and 100
# volume: 50
# # Where to store downloaded files
# download_dir: ~/Downloads
# # Play videos in fullscreen by default
# fullscreen: True
# # If youtube-dl or any compatible application is installed, play requested
# # videos in this format by default. Default: `best`.
# youtube_format: 'mp4[height<=?480]'
# # Extra arguments to pass to the executable. --play-and-exit may be a good
# # idea with VLC, so the player terminates upon stop instead of lingering in
# # the background.
# args:
# - --play-and-exit
# # List of directories to search for media files. The media files in these
# # folders can be searched through the `media.<player>.search` command, or
# # through the Web interface.
# media_dirs:

### ---------------------
### Sensors configuration
### ---------------------
###
# # The serial plugin can be used to read sensor data from a device connected
# # over serial/USB interface.
# #
# # It can be used, for example, to connect to an Arduino or ESP device over
# # serial port, where the remote microcontroller periodically sends sensor data
# # over the serial interface.
# #
# # The data can be sent on the wire either as raw string-encoded numbers (one
# # per line), or (better) in JSON format. For example, you can program your
# # microcontroller to periodically send JSON strings like these when you get new
# # readings from your sensors:
# #
# # {"temperature": 25.0, "humidity": 20.0, "smoke": 0.01, "luminosity": 45}
# #
# # The JSON will be automatically unpacked by the application, and the relevant
# # `platypush.message.event.sensor.SensorDataChangeEvent` events will be
# # triggered when the data changes - you can subscribe to them in your custom
# # hooks.
#
# serial:
# # The path to the USB interface with e.g. an Arduino or ESP microcontroller
# # connected.
# # A way to get a deterministic path name on Linux, instead of
# # `/dev/ttyUSB<n>`, can be the following:
# #
# # - Get the vendor and product ID of your device via e.g. `lsusb`. For
# # example, for an Arduino-compatible microcontroller:
# #
# # Bus 001 Device 008: ID 1a86:7523 QinHeng Electronics CH340 serial converter
# #
# # - In the case above, `1a86` is the vendor ID and `7523` is the product
# # ID. Create a new udev rule for it, so every time the device is
# # connected it will also be symlinked to e.g. `/dev/arduino`:
# #
# # echo 'SUBSYSTEM=="tty", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", SYMLINK+="arduino"' | \
# # sudo tee /etc/udev/rules.d/98-usb-serial.rules
# device: /dev/ttyUSB0
# # How often the interface should be polled for updates, in seconds
# poll_interval: 1
# # The tolerance argument can be used to tune when you want to be notified
# # of data changes through `SensorDataChangeEvent` events. In the case
# # below, if the microcontroller sends two consecutive temperature reads,
# # one for 22.0 and one for 22.2, then only one `SensorDataChangeEvent` will
# # be triggered (for the first read), since the absolute value of the
# # difference between the two events is less than the configured tolerance.
# # However, if the device sends two temperature reads, one for 22.0 and one
# # for 22.7, then two `SensorDataChangeEvent` events will be triggered.
# # The tolerance for all the metrics is set to a value close to zero by
# # default - i.e. any read, unless it's exactly the same as the previous
# # one, will trigger a new event.
# tolerance:
# temperature: 0.5
# humidity: 0.75
# luminosity: 5
#
# # If a threshold is defined for a sensor, and the value of that sensor goes
# # below/above that temperature between two reads, then a
# # `SensorDataBelowThresholdEvent` or a `SensorDataAboveThresholdEvent` will
# # be triggered respectively.
# thresholds:
# temperature: 25.0
###
###
# # Alternatively to the serial plugin, you can also use the arduino plugin if
# # you want to specifically interface with Arduino.
# #
# # This plugin won't require you to write any logic for your microcontroller.
# # However, it requires your microcontroller to be flash with the Firmata
# # firmware, which allows programmatic external control.
# #
# # Note that the interface of this plugin is basically the same as the serial
# # plugin, and any other plugin that extends `SensorPlugin` in general.
# # Therefore, poll_interval, tolerance and thresholds are supported here too.
#
# arduino:
# board: /dev/ttyUSB0
# # name -> PIN number mapping (similar for digital_pins).
# # It allows you to pick a common name for your PINs that will be used in
# # the forwarded events.
# analog_pins:
# temperature: 7
#
# tolerance:
# temperature: 0.5
#
# thresholds:
# temperature: 25.0
###
###
# # Another example: the LTR559 is a common sensor for proximity and luminosity
# # that can be wired to a Raspberry Pi or similar devices over SPI or I2C
# # interface. It exposes the same base interface as all other sensor plugins.
#
# sensor.ltr559:
# poll_interval: 1.0
# tolerance:

# proximity: 5.0
#
# thresholds:
# proximity: 10.0

###
###
# # `tts.google` leverages Google's official text-to-speech API to render audio
# # speech from text.
# #
# # Install its dependencies via 'pip install "platypush[google-tts]"'.
# #
# # Like all other Google integrations, it requires you to register an app on the
# # Google developers console, create an API key, and follow the instruction
# # logged on the next restart to give your app the required permissions to your
# # account.
#
# tts.google:
# # The media plugin that should be used to play the audio response

###
## ----------
## Procedures
## ----------
# Procedures are lists of actions that are executed sequentially.
#
# This section shows how to define procedures directly in your YAML
# configuration file(s). However, you can also put your procedures into Python
# scripts inside of the `<config-dir>/scripts` directory if you want access to
# a full-blown Python syntax. They will be automatically discovered at startup
# and available to the application.
#
# You can also access Python variables and evaluate Python expressions by using
# `${}` context expressions.
#
# The `context` special variable is a name->value dictionary containing the
# items returned from previous actions. For example, if an action returned
# `{"status": "ok", "temperature": 21.5}`, then the following actions can access
# those variables through `${context["status"]}` or
# `${context["temperature"]}`, or simply `${status}` and `${temperature}`,
# respectively.
#
# You can also add statements like `- if ${temperature > 20.0}` or
# `- for ${temp in temperature_values}` in your procedures.
#
# Besides the `context` variables, the following special variables are also
# available to the `${}` constructs when running a procedure:
#
# - `output`: It contains the parsed output of the previous action.
# - `errors`: It contains the errors of the previous action
# - `event`: If the procedure is an event hook (or it is executed within an
# event hook), it contains the event that triggered the hook
###
# # An example procedure that can be called when you arrive home.
# #
# # You can run this procedure from the Platypush `execute` Web panel, or
# # programmatically by sending a JSON request to your Web server (or to the
# # `/ws/requests` Websocket route, or to the TCP backend)
# #
# # curl -XPOST \
# # -H "Authorization: Bearer $YOUR_TOKEN" \
# # -d '{"type": "request", "action": "procedure.at_home"}'
# #
# # A use-case can be the one where you have a Tasker automation running on your
# # Android device that detects when your phone enters or exits a certain area,
# # and sends the appropriate request to your Platypush server.
#
# procedure.at_home:
# # Set the db variable AT_HOME to 1.
# # Variables are flexible entities with a name and a value that will be
# # stored on the database and persisted across sessions.
# # You can access them in other procedures, scripts or hooks and run
# # custom logic on the basis of their value.
# - action: variable.set
# args:
# AT_HOME: 1
#
# # Check the luminosity level from e.g. a connected LTR559 sensor.
# # It could also be a Bluetooth, Zigbee, Z-Wave, serial etc. sensor.
# - action: sensor.ltr559.get_measurement
#
# # If it's below a certain threshold, turn on the lights.
# # In this case, `light` is a parameter returned by the previous response,
# # so we can directly access it here through the `${}` context operator.
# # ${light} in this case is equivalent to ${context["light"]} or
# # ${output["light"]}.
# - if ${int(light or 0) < 110}:
# - action: light.hue.on
#
# # Say a welcome home message
# - action: tts.mimic3.say
# args:
# text: Welcome home
#
# # Start the music
# - action: music.mpd.play
###
###
# # Procedure that will be execute when you walk outside your home.
#
# procedure.outside_home:
# # Unset the db variable AT_HOME
# - action: variable.unset
# args:
# name: AT_HOME
#
# # Stop the music
# - action: music.mpd.stop
#
# # Turn off the lights
# - action: light.hue.off
###
###
# # Procedures can also take optional arguments. The example below shows a
# # generic procedure that broadcasts measurements from a sensor through an
# MQTT broker.
#
# # A listener on this topic can react to an `MQTTMessageEvent` and, for
# # example, store the event on a centralized storage.
# #
# # See the event hook section below for a sample hook that listens for messages
# # sent by other clients using this procedure.
#
# procedure.send_sensor_data(name, value):
# - action: mqtt.send_message
# args:
# topic: platypush/sensors
# host: mqtt-server
# port: 1883
# msg:
# name: ${name}
# value: ${value}
# source: ${Config.get("device_id")}
###
## -------------------
## Event hook examples
## -------------------
# Event hooks are procedures that are run when a certain condition is met.
#
# Check the documentation of your configured backends and plugins to see which
# events they can trigger, and check https://docs.platypush.tech/events.html
# for the full list of available events with their schemas.
#
# Just like procedures, event hooks can be defined either using the YAML
# syntax, or in Python snippets in your `scripts` folder.
#
# A YAML event hook consists of two parts: an `if` field that specifies on
# which event the hook will be triggered (type and attribute values), and a
# `then` field that uses the same syntax as procedures to specify a list of
# actions to execute when the event is matched.
###
# # This example is a hook that reacts when an `MQTTMessageEvent` is received on
# # a topic named `platypush/sensor` (see `send_sensor_data` example from the
# # procedures section).
# #
# # It will store the event on a centralized Postgres database.
# #
# # Note that, for this event to be triggered, the application must first
# # subscribe to the `platypush/sensor` topic - e.g. by adding `platypush/sensor`
# # to the active subscriptions in the `mqtt` configurations.
#
# event.hook.OnSensorDataReceived:
# if:
# type: platypush.message.event.mqtt.MQTTMessageEvent
# topic: platypush/sensor
# then:
# - action: db.insert
# args:
# engine: postgresql+pg8000://dbuser:dbpass@dbhost/dbname
# table: sensor_data
# records:
# - name: ${msg["name"]}
# value: ${msg["value"]}
# source: ${msg["source"]}
###
###
# # The example below plays the music on mpd/mopidy when your voice assistant
# # triggers a speech recognized event with "play the music" content.
#
# event.hook.PlayMusicAssistantCommand:
# if:
# type: platypush.message.event.assistant.SpeechRecognizedEvent
# # Note that basic regexes are supported for `SpeechRecognizedEvent`,
# # so the hook will be triggered both if you say "play the music" and
# # "play music"
# phrase: "play (the)? music"
# then:
# - action: music.mpd.play
###
###
# # This will turn on the lights when you say "turn on the lights"
#
# event.hook.TurnOnLightsCommand:
# if:
# type: platypush.message.event.assistant.SpeechRecognizedEvent
# phrase: "turn on (the)? lights?"
# then:
# - action: light.hue.on
###
###
# # The WebhookEvent is a special type of event. It allows you to dynamically
# # register a Web hook that can be invoked by other clients, if the HTTP backend
# # is active.
# #
# # In this case, we are registering a hook under `/hook/test-hook` that accepts
# # POST requests, gets the body of the requests and logs it.
# #
# # NOTE: Since Web hooks are supposed to be called by external (and potentially
# # untrusted) parties, they aren't designed to use the standard authentication
# # mechanism used by all other routes.
# #
# # By default they don't have an authentication layer at all. You are however
# # advised to create your custom passphrase and checks the request's headers or
# # query string for it - preferably one passphrase per endpoint.
#
# event.hook.WebhookExample:
# if:
# type: platypush.message.event.http.hook.WebhookEvent
# hook: test-hook
# method: POST
# then:
# # Check the token/passphrase
# - if ${args.get('headers', {}).get('X-Token') == 'SECRET':
# - action: logger.info
# args:
# msg: ${data}
###

### Cron examples
### -------------
###
# # Cronjobs allow you to execute procedures at periodic intervals.
# # Standard UNIX cron syntax is supported, plus an optional 6th indicator
# # at the end of the expression to run jobs with second granularity.
# # The example below executes a script at intervals of 1 minute.
#
# cron.TestCron:
# cron_expression: '* * * * *'
# actions:
# - action: shell.exec
# args:
# cmd: ~/bin/myscript.sh
