Running as a daemon with systemctl

Hi All,

running as a daemon does’t work for me, please advice.
Status “systemctl status zigbee2mqtt.service” gives following result:

 openhabian@openHABianPi:~$ systemctl status zigbee2mqtt.service

● zigbee2mqtt.service - zigbee2mqtt
Loaded: loaded (/etc/systemd/system/zigbee2mqtt.service; enabled; vendor preset: enabled)
Active: active (running) since Wed 2020-02-12 22:42:57 CET; 707ms ago
Main PID: 29771 (npm)
Tasks: 7 (limit: 4915)
CGroup: /system.slice/zigbee2mqtt.service
└─29771 npm

lut 12 22:42:57 openHABianPi systemd[1]: Started zigbee2mqtt.

can someone advice on what’s wrong?
Looks like it’s running but clearly sth. is missing comparing to instruction:

 CGroup: /system.slice/zigbee2mqtt.service
           ├─665 npm
           ├─678 sh -c node index.js
           └─679 node index.js

The rest works superb!
