If this is not the right place to post a this question, please say.
I’m running zigbee2mqtt (Zigbee broker) on a USB dongle device (CC2531 with antenna, forgot the antenna model) and a Linux machine (KDE neon User Edition 5.19, based on Ubuntu 18.04). Sometimes zigbee2mqtt stops working and I have to change the ownership of the device (with chown) to successfully run it again. So I put it in one script:
~/my_services/zigbee2mqtt_service $ cat z2m.sh sudo chown gal /dev/ttyACM0 cd /opt/zigbee2mqtt npm start
and created a service in systemd to run the script:
~/my_services/zigbee2mqtt_service $ systemctl cat zigbee2mqtt.service # /etc/systemd/system/zigbee2mqtt.service [Unit] Description=zigbee2mqtt After=network.target [Service] # ExecStart=/usr/local/bin/npm start # WorkingDirectory=/opt/zigbee2mqtt ExecStart=/home/gal/my_services/zigbee2mqtt_service/z2m.sh StandardOutput=inherit StandardError=inherit Restart=always User=gal [Install] WantedBy=multi-user.target
This used to work, but for some reason, now the service won't start. I’m tried enabling it, starting manually, and to reload daemon. If I run the z2m.sh script manually it works well, but I’m working from a remote machine so I have to disconnect, which stops zigbee2mqtt.
It’d be great if you can point me to what to fix, or to a different way to recover from the ‘revoked ownership’.
Edit: This is what I get when checking the service status:
