First of all be aware with the description. There is ony one device that is sent. the "Two peices" is to explain that the component is composed by two elements, but you will receive only a single device... then it means it cost twice the price I was expecting. Regarding the sensor itself, it is a perfect quality (as usual with xiaomi). The pairing with Mi Home gateway is easy and is working perfectly fine. As I mentionned in my comment of the gateway, the very intersting point is the compability with Domoticz which make this really good for home automation. Note that the sensor is really tiny and that is sending a trigger for both openning and closing the door/windows.

A bit pricey I thought they sell them in 2 pair as said by the customer service. But when I received the box it was only 1 pair. When I put a complaint they revise the item description in the item page.
