Aqara has announced it's first Matter camera G350 earlier this year and I'm guessing it will be available around spring. Usually, Home Assistant is up to date with the standard but it's behind, I think with the whole 1.5 release from last autumn.
I have seen feature request for this : https://github.com/orgs/home-assistant/discussions/2596 but no indication on work being done on that front. Have I missed something ?
