I have 4 Tuya zigbee locks

• 3x deadlocks, ID: bf17b2f494f86f27a86y53

• 1x mortice lock with handle, ID: bf2379caed03ea0c6fygsz
  e.g. https://a.aliexpress.com/_mNByxar

All connected to a Zemismart M1 Matter hub, ID: bf8d9d92318c34b022d6qh.

All 4 locks show up in Home Assistant via the Matter integration, and I can see the lock state correctly.

However, only the mortice lock allows me to control the lock from Home Assistant. I can unlock and lock the mortice lock directly from the Matter device entity in Home Assistant.

The 3 deadlocks show their status (locked/unlocked) in Home Assistant, but if I try to control them, they show "Unlocking" (or "Locking") for about a minute before reverting to the original state. Nothing happens at the lock

I would like to be able to control all the locks from within Home Assistant. Are you able to help?

Is there any other information I can provide to assist in your analysis?

Hi. Sorry to keep you waiting so long.

Please control these two locks separately again, and record the time of operation, as well as the specific action of the operation and the actual action of the device.

Looking forward to your next reply, I will try my best to reply promptly. (But we will start the Spring Festival holiday on 2025/1/28, so please reply as soon as possible!)

I have just tried this minute. Firstly locked then unlocked with the Tuya app, then tried locking with Home Assistant.

Tuya actions successful. Home Assistant shows "Locking" for 40 seconds then fails back to Unlocked state.

Now trying device bf54c1fb3033c3a86bo843.

Locked and unlocked successfully with Tuya app.

Same non-result trying to lock with Home Assistant.

For comparison and to show the working connection, I have just now successfully unlocked device bf54c1fb3033c3a86bo843 (the mortice lock) with HA

I have received your feedback, wait for me to analyze the reason.
