These are brilliant, integrates well with Google home to check whether you have any ft a door open. They have their own alarm function that triggers notifications on the app.

Excellent product.
This little sensor is responsible and relatively quick to setup up. Work perfectly with the SmartLife app. When pairing go to [Add Device] => [Others] => [Connector (Wi-Fi)] option. Otherwise, the instruction in the manual doesn’t seem to do the trick.
