Works. Together with the purchase I recommend taking and the battery, not included. Shipping fast. Alarm sent to the app (40 km away). I have not yet figured out whether the system can remove (call).

Detectors work as described. It was easy to get them connected to Tuya app which pushes the alarm through when sensing water. Also the detector is yelling when sensing. I recommend!
