class ZigbeeMqttPlugin(MqttPlugin):
"""
This plugin allows you to interact with Zigbee devices over MQTT through any Zigbee sniffer and
`zigbee2mqtt <https://www.zigbee2mqtt.io/>`_.
In order to get started you'll need:
- A Zigbee USB adapter/sniffer (in this example I'll use the `CC2531 <https://hackaday.io/project/163487-zigbee-cc2531-smart-home-usb-adapter>`_.
- A Zigbee debugger/emulator + downloader cable (only to flash the firmware).
Instructions:
- Install `cc-tool <https://github.com/dashesy/cc-tool>`_ either from sources or from a package manager.
- Connect the Zigbee to your PC/RaspberryPi in this way: USB -> CC debugger -> downloader cable -> CC2531 -> USB.
The debugger and the adapter should be connected _at the same time_. If the later ``cc-tool`` command throws up
an error, put the device in sync while connected by pressing the _Reset_ button on the debugger.
- Check where the device is mapped. On Linux it will usually be ``/dev/ttyACM0``.
- Download the latest `Z-Stack firmware <https://github.com/Koenkk/Z-Stack-firmware/tree/master/coordinator>`_ to your device.
Instructions for a CC2531 device:
.. code-block:: shell
wget https://github.com/Koenkk/Z-Stack-firmware/raw/master/coordinator/Z-Stack_Home_1.2/bin/default/CC2531_DEFAULT_20190608.zip
unzip CC2531_DEFAULT_20190608.zip
[sudo] cc-tool -e -w CC2531ZNP-Prod.hex
- You can disconnect your debugger and downloader cable once the firmware is flashed.
- Install ``zigbee2mqtt``. First install a node/npm environment, then either install ``zigbee2mqtt`` manually or through your
package manager. Manual instructions:
.. code-block:: shell
# Clone zigbee2mqtt repository
[sudo] git clone https://github.com/Koenkk/zigbee2mqtt.git /opt/zigbee2mqtt
[sudo] chown -R pi:pi /opt/zigbee2mqtt # Or whichever is your user
# Install dependencies (as user "pi")
cd /opt/zigbee2mqtt
npm install
- You need to have an MQTT broker running somewhere. If not, you can install
`Mosquitto <https://mosquitto.org/>`_ through your package manager on any device in your network.
- Edit the ``/opt/zigbee2mqtt/data/configuration.yaml`` file to match the configuration of your MQTT broker:
.. code-block:: yaml
# MQTT settings
mqtt:
# MQTT base topic for zigbee2mqtt MQTT messages
base_topic: zigbee2mqtt
# MQTT server URL
server: 'mqtt://localhost'
# MQTT server authentication, uncomment if required:
# user: my_user
# password: my_password
- Also make sure that ``permit_join`` is set to ``True``, in order to allow Zigbee devices to join the network
while you're configuring it. It's equally important to set ``permit_join`` to ``False`` once you have
configured your network, to prevent accidental/malignant joins from outer Zigbee devices.
- Start the ``zigbee2mqtt`` daemon on your device (the
`official documentation <https://www.zigbee2mqtt.io/getting_started/running_zigbee2mqtt.html#5-optional-running-as-a-daemon-with-systemctl>`_
also contains instructions on how to configure it as a ``systemd`` service:
.. code-block:: shell
cd /opt/zigbee2mqtt
npm start
- If you have Zigbee devices that are paired to other bridges, unlink them or do a factory reset to pair them
to your new bridge.
- If it all goes fine, once the daemon is running and a new device is found you should see traces like this in
the output of ``zigbee2mqtt``::
zigbee2mqtt:info 2019-11-09T12:19:56: Successfully interviewed '0x00158d0001dc126a', device has successfully been paired
- You are now ready to use this integration.
