When you go on the main website there is a wite box on the left hand side that says “Current Version”. In that box there is a link that says “Release Notes”. Click on it. Right now it points to the release notes for 0.109 which are here. You can search for homekit_controller to find stuff that might be related to this.
Right now you won’t find anything. After the massive push at the start of the year (arguably used more time than i actually had to give) i’ve run out of free time and what I do have is currently going on triaging bug reports (especially regressions), not new features. E.g. last night another Aqara user was having trouble with unstable async connections. We found the Aqara can’t handle the level of concurrency we used by default and when I have time i’ll be putting in a PR for that bug.
With where we are in the release cycle, the lack of anyone else contributing to homekit_controller, and my crippling lack of free time I can’t tell you when the change will land. I would say it almost certainly won’t be in 0.110.
But it is a feature that is coming. It is the priority new feature. I have this type of device myself and i want it to work with Home Assistant. I got a prototype working already. The problem is really just one of refactoring the prototype so that it is suitable for code review (it took shortcuts that aren’t of sufficient quality).
