Wireless Door Magnetic Standalone Sensor

Good sensor based on magnet. Works always for sure almost without delays. The Wi-Fi module is quite normal. Now I know when someone came, or left))

Still not tested but the product looks good quality! After testing back here to speak more product! The shipping was fast and arrived well packaged without being taxed! For now recommend the seller!

Sensors are excellent, ordered 2 PCs-both work without problems. I recommend to buy.

It's okay.
Opened-notification.
Closed-notification.
You can configure that only opening/closing will be triggered.
There is a history of opening the door, time and date.

Sensor of very good quality apparent. Adhesive is provided which allows to install it immediately. Works very well with smartlife. There is more to wait to know the autonomy of the batteries. I will certainly buy others. Thank you
