I’ve just acquired an Aqara Hub M1S (really cheap on sale, so appears to be a gen-1; surprise). Anyway, I did get it paired to HA (as a HomeKit Device), and it shows up in Apple Home. And firmware got updated on the hub, so it also functions as a Matter bridge.
I’ve been able to get one user-visible piece of the thing operating in HA, and that’s the built-in night light LED ring --both as a device under HomeKit Device, AND as a Matter device, both having full RGB light control.
But I’m wondering if the hub’s built-in illuminance sensor, and built-in siren/speaker, are accessible in any way from HA?
I haven’t connected any Zigbee devices thru the hub yet; currently just trying to get all the built-in bits going in the hub (if possible).
