Items arrived on schedule, well-made packaging, but I would suggest opting for rigid external packaging, 2 of the 3 rooms had the box dented (as seen in the photo). I’ll Try them shortly by integrating my assessment.
At first glance they seem well built and the technological quality, from the video reviews I have seen from other users, is excellent. Satisfied!

Arrived before the deadline, apparently supports what it promises, I used in a project that is in the photo of automation… Let’s see in time how it behaves… Detail even for networks 220V or 380V need to pass the neutral, because I bought it thinking that only the two phases were sufficient

It’s really too good. Think about taking the WI-FI version. Otherwise the other version you will need the hub in addition.
The wifi version perfectly connecting to all of my connected devices. I can ask Google if “door” is “open” where “closed”.
At home, the device remains very discreet if the door opens, only a blue light flashing once. An open door notification reaches you on your smartphone. It’s great…!!! Thank you!

Worked very well ..
It is very well finished and uses good materials

OK thank you
