Rediscovered zigbee devices- fail to show in pairing page, but do get reconnected.
This had been happening for some time but I never reported it
I had that happen too. I didn't think about it at the time, but now that you mention it... it does seem like a bug.
Mine happened on 2.19, you getting the same on 2.20?
Yes, same behavior on 2.20. I mean thankfully we have the ability to reconnect, but by it not being spelled out people might think otherwise. I only stumbled on this by accident. I had repaired my fan controller, and thinking it was still failed I gave up as it never showed on the webpage, but later that night when I walked past the motion sensor the fanlight came on.
And it's not an always failure, it will sometimes display the device that was re-paired.
FWIW. SmartThings exhibits this exact same behavior.
