Aqara U200 Smart Lock - Silent/Quiet Mode not available via Matter or Home Assistant. Anyone found a workaround? I have two Aqara Smart Lock U200s integrated in Home Assistant via Matter over Thread. Works great for basic locking/unlocking, but I've been trying to automate the **Quiet Unlock Mode** (silent mode) - e.g. turn it on at 22:00 and off at 07:00 so it doesn't wake up the kids at night. After digging into it: * **Matter** doesn't expose silent mode, it's not a standard Matter Lock Cluster attribute * **HA entity list** for the U200 only shows lock, battery sensor, firmware update, and identify button. No switch/select for sound/quiet mode. * **Aqara Cloud API** theoretically exists (opendoc.aqara.com) but silent mode doesn't appear to be a documented/exposed resource, and it requires a full OAuth developer setup * **Aqara Home app** does have the setting, but you can't trigger it from HA Has anyone managed to control the U200's quiet mode from Home Assistant?…
