I had it installed and working well with an Ikea motion sensor then Matter seemed to have disappeared from HA and I can’t reconfigure. In Setting–>Matter I only get a blank screen – nothing ever populates in that menu. When I try re-adding Matter as an Integration it appears to work (I have the box “Use the official Matter supervisor app” checked). It then states that Matter was successfully configered, but it’s nowhere to be seen. Doesn’t show up in my Integrations. I don’t mind starting over, but what do I need to do to get it back to square one and functional again?
I may have figured this out. Somehow the Matter integration had become disabled. Re-enabling has brought it back to the Integrations menu. Some Matter devices are being stubborn but that’s likely a different matter (haha).
