When you reset the zigbee implementation, a quiet channel gets picked by Homey. Make sure your wifi is on a fixed channel prior to the actual resetting, preferrably 1, 6 or 11
A reset breaks all zigbee device connections
You pick the zigbee channel yourself here (without a reset that is).
Which channel to pick?
Examples:
wifi 1 - zigbee 25
Wifi 6 - zigbee 11 or 25
Wifi 11 - zigbee 11 or 15
