Yeah, in ZHA there is a zigbee.db but I’m not sure that stores all of the paring info, tho. It might I’m just not sure one way or the other.
As a point of comparison there is also a zwave config xml file in HA as well but all of the zwave pairing info is stored on the controller. Which is why you should be able to technically pull the stick out of the machine and pair the devices by using the pairing button on the stick itself. Then the xml file should be re-created when the stick is re-inserted. Granted, it’s not always successful and not recommended by HA but the fact that it works at all tells me that the pairing info is on the stick, not in HA itself.
I just assumed ZHA worked similarly (except for the offline pairing part).
But one question tho is that if a Conbee user switches to a different (non-HA) system that supports the use of the Conbee stick will the stick and zigbee network be useless (without re-pairing everything) unless the old zigbee.db file is transferred to the new system?
I really don’t know.
Either way it’s just academic.
To the OP, once you flash the new bridge do a test and switch to it and see if it works. Then you’ll know for sure.
