The first question to ask is what version of the binding are you using?
ZigBee doesn’t have a heal - it works very differently to ZWave and battery devices are also quite different.
I don’t see anything in the logs about devices going offline, and this would not impact on what is being seen here since the OFFLINE issue is only related to the OH state and not the network operation.
@Robotto Please also use code fences when posting logs so that they are easier to read (thanks).
