As of Homey firmware 10.1.0-RC4 matter buttons are working now. I checked the Hue buttons I have. Working like a charm via Homey now! Almost instant reaction from the Hue tap switch! Much better performance than via the HUE app.
I will continue to test other buttons.
UPDATE: reading through the release notes this update should also fix the issues people had with lots of hue devices connected to one bridge? Unfortunately I do not have so many connected devices to mij bridge. So unable to test.
