Zigbee2mqtt - Power cut generate Error: Failed to connect to the adapter

Hello All,

Here is my configuration :

  • Home Assistant in HASSIO running on a raspberry 4
  • SONOFF Zigbee 3.0 USB Dongle Plus (ZBDongle-P)

the usb configuration is correctly set :

  • port: >-
    /dev/serial/by-id/usb-ITead_Sonoff_Zigbee_3.0_USB_Dongle_Plus_901286afb1c9eb118979914f1d69213e-if00-port0

My problem is the following : every time I have a power cut zigbee2mqtt cannot reconnect to the adapter. I found a workaround which is to unplug for 10s, replug the usb adapter and restart zigbee2mqtt addons, but it’s kind of complex when not at home and it annoys the others customers of the service (my wife mainly).

I would like that it restarts without any intervention of my hand. Does any of you already experience this issue (and found a way to solve it) ?

Any workaround appreciated, I already imagined the following :

Thanks for your feedbacks, advices and help !

Regards,
