There‘s no real Solution, except deleting the integration, or?
Doesn’t work
I can’t believe such a simple basic functionality is missing. I tried @marioth1’s solution, but it doesn’t seem to work for me.
I don’t understand. Why can’t we get the pairing pin shown again? I have a selected list of devices exposed to HomeKit. It’s not long, but it is by no means short. Especially when the UI is just a list in a tiny select box.
Deleting the instance and re-making it is an extremely troublesome thing to have to do.
I’m not sure what even happened, but my entire list of devices stopped showing in my HomeKit. I wanted to re-pair to try to fix it, but I can’t even do that?
This just seems really wild to me.
