This feature is already included in the Matter specifications:
MatterScheduleConfiguration Feature
This feature indicates that the thermostat is capable of schedules. If this feature is supported, the thermostat SHALL support a mechanism to do time synchronization.
Error: After enabling “Valve Detection Notification,” a malfunction occurs after a while. You don’t receive any notifications, the device displays an exclamation point in a triangle, and app control becomes unavailable. However, Smart Schedules continue to work.
Removing and reconnecting the device in the Aqara Home app resolves this issue.
If you leave the device alone and do not control it through the app, then after about 4-5 days the device becomes offline and it is no longer possible to control it remotely.
