Raspberry Pi4 Homebridge Zigbee2MQTT setup

stain3565 · January 29, 2022, 8:19pm

My main automation system is Home Assistant on Raspberry Pi4 but I currently access Nest Protect via the HA plugin and Homebridge on another Pi4.

I already use ZHA on HA for a Conbee II but have just recently bought a SONOFF Zigbee 3.0 USB Dongle Plus in an attempt to integrate a few Sonoff Zigbee buttons, which appear to have no actions available in Home Assistant. I thought the Sonoff dongle would help with compatibility.

As I do not want to use Deconz with my Conbee i HA (this has been very unreliable whereas I have had no issues with ZHA), I thought I would integrate the Sonoff dongle and buttons via Homebridge.

I have been following the instructions via this post but have come unstuck with installing [Zigbee2MQTT] (Linux | Zigbee2MQTT) on the Homebridge Pi4.

I have successfully started Zigbee2MQTT manually with just 3 warnings but looks ok :

pi@homebridge:/var/lib/homebridge $ cd /opt/zigbee2mqtt
pi@homebridge:/opt/zigbee2mqtt $ npm start

> node index.js

However, when attempting to run as a daemon, I have had no success. Initially I got a 205 error but lately have just got the following:

pi@homebridge:/opt/zigbee2mqtt $ sudo systemctl start zigbee2mqtt
Warning: The unit file, source configuration file or drop-ins of zigbee2mqtt.service changed on disk. Run 'systemctl daemon-reload' to reload units.
pi@homebridge:/opt/zigbee2mqtt $

My service code is as follows:

[Unit]
Description=zigbee2mqtt
After=network.target

[Service]
ExecStart=/usr/bin/npm start
WorkingDirectory=/opt/zigbee2mqtt
StandardOutput=null
# Or use StandardOutput=null if you don't want Zigbee2MQTT messages filling syslog, for more options see systemd.exec(5)
StandardError=inherit
Restart=always
User=pi

[Install]
WantedBy=multi-user.target

I did try the “ExecStart=/usr/local/bin/npm start” as well, even though my Pi is version 4B.

The suggested daemon reload results in the following:

pi@homebridge:/opt/zigbee2mqtt $ systemctl daemon-reload
Failed to reload daemon: Interactive authentication required.
pi@homebridge:/opt/zigbee2mqtt $

Any ideas what I am doing wrong?

Make sure user pi is a member of the dailout group.

And are you logged in as user pi at the moment you start the daemon ?

I am connected to Homebridge via the admin user but Terminal is opening as pi@homebridge, as seen below.

Still failing.

pi@homebridge:/var/lib/homebridge $ sudo usermod -a -G dialout pi
pi@homebridge:/var/lib/homebridge $ sudo systemctl start zigbee2mqtt
Warning: The unit file, source configuration file or drop-ins of zigbee2mqtt.service changed on disk. Run 'systemctl daemon-reload' to reload units.
pi@homebridge:/var/lib/homebridge $ ^C
pi@homebridge:/var/lib/homebridge $ systemctl daemon-reload
Failed to reload daemon: Interactive authentication required.
pi@homebridge:/var/lib/homebridge $

I should say that my mqtt mosquitto broker is on my Home Assistant raspberry pi, not the Homebridge pi. This means that I am connecting to core-mosquitto via the HA ip address.
