Hi, the conbee 2 stick I have changes its IP whenever there’s a power outage to my Home Assistant device. This results in HA not being to reconnect when power is restored. I have to repair the conbee stick and rename all the devices that are connected to it. Any solutions to this?
The conbee-II stick and doesn’t have an IP address; only TCP devices have an ip address…
Maybe you ment it switches USB port?
I suggest you use ‘by-id’ instead of ttyACM0…
port can vary, but the ID can not 
Not sure if you are using Zigbee2mqtt, but this is my port config:
port: >-
/dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE2481787-if00
adapter: deconz
Instead of using
ttyACM0
