Very bad
Didn’t last a month and since the start the unit is defective. Intermittently the status remains open though the door is closedI have very minimal gap between the sensor units .

The product is useful. I am using it to turn lights automatically on when the door opens as I am also having smartlife light switches.👍

Does the job but battery doesn't last long...
Enough to notify you if a door or window opens or shuts, but the battery barely lasted 2 weeks and I did not get a battery notification, seems that is can't detect the AAA battery capacity nor discharge rate...

Good product. Serves the purpose.
Good to program automation and routines if you have other Tuya devices.Battery backup is low. Drained 10% in a week.

Stoped working properly after 3 weeks
It was working fine at first, then after three weeks it started hanging and not changing its status from closed to open and vice verse..
