Xiaomi Door Sensor occasionally offline after RPI reboot


I use a bunch of Xiaomi door/window sensors (model MCCGQ01LM). Here and there after a RPI reboot one of the sensors goes offline (shown as unavailable in HA) and I need to reset the sensor to get it back online. The sensors are not easily accessible so I would prefer to “wake up” the unavailable sensor remotely, if possible.


  • RPI 4 with HA on SSD
  • Controller is Conbee II
  • Zigbee2mqtt
  • I have a zigbee repeater in almost every room so network connectivity is good

Any ideas how to wake up unavailable sensors remotely?
