I have three of these locks integrated via Matter in Home Assistant.
The lock and unlock features work perfectly and near instantaneously. They even keep on working consistently through HA reboots and updates.
The Door Sensors on the other hand is a different story. They show up as Unknown quite often. When these sensors become unresponsive, I have to pull a battery to “reboot” the lock. These sensors often don’t survive an HA reboot or update.
Since the lock/unlock states and functions work fine, this rules out Matter/Thread network issues entirely.
Is there a way you guys could update the firmware to restart the sensor when the DoorState Attribute returns a value of 4? This value shows up in HA as Unknown and in the U Home app the Open/Close Icon and label are in/showing a Closed state when the door is opened and closed. Pulling a battery every few days is quite annoying and makes this sensor unreliable for use in “security” type automations which in my opinion, should be just as critical
Since this sensor gets “stuck” - the feature that turns on a chime when the door is left open for X seconds doesn’t function as well.
