Homekit controller failing to reconnect after long power cut

[Dtrotmw]

The problem

I had a long power cut yesterday and the Homekit controller which provides access to a Heatmiser NeoHub wont reconnect. The network is working fine and the router reports the hub still connected to the same IP address.
The supplier has reset the device & I've pressed "pair" on the hub. The Android app provided by Heatmiser is still working.

What version of Home Assistant Core has the issue?

Home Assistant 2023.1.6 Supervisor 2022.12.1 Operating System 9.4 Frontend 20230110.0 - latest

Hey there @jc2k, @bdraco, mind taking a look at this issue as it has been labeled with an integration (homekit_controller) you are listed as a code owner for? Thanks!

When you say reset, have they reset HomeKit? And then you have removed the integration in HA and re-added it?

[Dtrotmw]

Heatmiser have reset the Homekit so it now appears as an unpaired device that I tried adding (add integration>Apple>Homekit Controller>Device Selection> Heatmiser neoHub>submit). On the page asking for the pairing code it displays

An unhandled error occurred while attempting to pair with this device. This may be a temporary failure or your device may not be supported currently: Connection closed

And it won’t accept the pairing code.

[Jc2k]

The log that you attached doesn't show that - can you show me a pairing failure log please?

Your log does shows /pair-verify attempts. It looks like we are either unable to hold a connection to the device or the homekit service on the device is closing the connection without answering.

So this is sounding like the last ticket you raised - #85317 (unexplained connection closed errors).

If there aren't connectivity issues with the device, and you have verified the ports being used are correct with the Service Browser app or similar like before, then I think your hub is in a weird state still and not serving HomeKit properly.

I think this is the log entry you asked for:

I need more, that doesn't give me the context. It just tells me that your hub dropped the connection.

[Dtrotmw]

That's all that is in either log file with that timestamp (.log and .log.1). Where do I find what you need?

[Jc2k]

How did you get the log files you attached to the original bug report?

[Dtrotmw]

By selecting "enable debug logging" at the integration. The supplier issued another reset and I've now successfully added the integration, so you were right in thinking it was some wierd state in the neohub. The trouble is I've now got a second set of 49 entities with the _2 suffix. Is there any simple way I can avoid re-building everything I've used that refers to them?

[Jc2k]

In HA there are entities and devices. It sounds like you have duplicated entities but from your description I don't know if you have duplicate devices. Are you able to post screenshots of this from your device page?

[Dtrotmw]

2 copies of all the Heatmiser devices!

[Dtrotmw]

All sorted now after a session of changing all the entity names. It seems I managed to keep all the histories which was a big win. Thank you so much for all your help. it is much appreicated.
