Unable to add Siegenia window sensor to HomeAssistant by Matter

[matthias987654]

The problem

We are unable to add the Siegenia window sensor to HomeAssistant by Matter. The device is working with the Apple Home without any problems. But we can't add the device to HomeAssistant. We discussed that topic on the discord server without a solution. I tested it with the official release of the matter server and the beta version 6.1. It is the same error behaviour.

What version of Home Assistant Core has the issue?

2024.6.0

What was the last working version of Home Assistant Core?

Unknown

What type of installation are you running?

Home Assistant OS

Hm, it seems that late during the commissioning the device sens an error back to our Matter controller, which causes the device to drop.

The whole commissioning flow is pretty much straight from the official Matter SDK, so it is a bit surprising that this does not affect Apple 🤔

Did you commission it first with Apple and then with HA?

Did you try factory reset and do the opposite: Pair first with HA (and then with Apple?).

[matthias987654]

Yes - first Apple Home and then HomeAssistant. I didn't test it the other way around.

@matthias987654 Did you try to factory reset the device and give a another try?

[matthias987654]

Yes, same error after that. I am able to add the device as new device. But there is no possibility to add a second platform like Apple Home.

You could use the 'Share device' function for that. If it doesn't work, it's due to a limit on the number of Matter fabric on the device.

[matthias987654]

I used that. But it ends with an error during the enrollment on Apple Home, too.

So it's an device issue.

[matthias987654]

Siegenia is working on that topic. I am waiting for feedback from the developers of Siegenia.

This appears to be a device issue where the device can not handle Multi admin correctly (something we see more often with 1.0 devices). It will probably/hopefully be fixed by the vendor at some point. Its not a bug in HA Matter, so I'll close here.
