Zigbee2MQTT not starting / not working

[O815]

Hi, I recently installed Zigbee2Mqtt on my raspberry pi 3.
Everything worked fine but now I'm having a problem.
I want to use Zigbee2Mqtt as a daemon so I don't need to have ssh active.

I followed the tutorial on the "Linux installation" tap but now I can't reach the web interface anymore and on the logs, I can see that the service is not starting.

It's only working if I'm starting the service with these commands "cd /opt/zigbee2mqtt, npm start".
But at the moment I'm closing the ssh connection it stops.

Maybe someone in this forum has an idea?
Thank you very much in advance!

You would want to create a systemd unit file, though honestly... switching to Docker is likely to be overall simpler.

Here's an example systemd unit file that runs Zigbee2MQTT as the user zigbee:

[Unit]
Description=zigbee2mqtt
After=network.target

[Service]
ExecStart=/usr/bin/npm start
WorkingDirectory=/opt/zigbee2mqtt
StandardOutput=inherit
StandardError=inherit
Restart=always
User=zigbee

[Install]
WantedBy=multi-user.target
