Hey there @home-assistant/matter, mind taking a look at this issue as it has been labeled with an integration (matter
) you are listed as a code owner for? Thanks!

See our documentation - Matter is very sensitive to networking issues as it relies on multicast IPv6 traffic to travel freely on your network. Best thing to do is join our discord server (matter channel) to troubleshoot it but I would start by inspecting your network setup. Do you have any (semi) professional networking gear like Unifi etc. ?
Hi @marcelveldt, I might have agreed if it didn't work without a hitch with my Google Home border router directly. Leading me to believe that there's a bug in the Home Assistant implementation. I have read the documents and I currently use the farthest from a 'semi-professional' network setup. I'm using eero (Amazon) devices.
There is no bug - it works for thousands of people and in fact our code is using the exact same SDK as what is in your Google Home. But its very sensitive for network configuration issues/hiccups.
Also sharing from Google Home to other ecosystems can have some issues, did you try adding the device to HA first/only ?
Let's start with a few basic questions:
1) Did you enable IPv6 in your Home Assistant network set-up ? 2) Did you try adding it to HA first and then share to Google ?
Yes, IPv6 is enabled and I tried adding it via HA first. Only when that kept failing I tried to add it via the Google Home app/Google Border Router directly and sharing it from there. Interestingly the sharing from Google Home to HA only worked after a couple of tries. I know Matter can be a bit finicky, but a hundred percent success rate connecting to Google Home and an inconsistent behavior when connecting to HA seems indicative of a bug.
99% of the issues with Matter (especially Matter-over-Thread) devices is caused by networking issues. Some network gear filters out multicast traffic between wireless and ethernet for example, that is enough to completely ruin the experience.
Also some switches have super flaky IGMP/MLD snooping implementations resulting in bad experience.
The problem
I tried to add the light multiple times via the companion app. It always fails. I was able to add it to Google Home multiple times and after trying to share the device multiple times from Google Home to Home Assistant it finally succeeded. There seems to be something wrong with commissioning.
