Do not make the mistake and buy it! The vtac smart home app no longer exists! I downloaded the vtac smart light which is supposed to have everything now there! I connected it and it reads it as an air-conditioner!!!! I unpaired it to see if it would actually find any a/c, but nothing! As soon as you press the button to pair it, it finds it and decides on its own that it is an a/c! By the way, if you use a test screwdriver, it seems to give power! 2 devices that I tried do not work! Of course, I tried them in different sockets and they work fine! Money wasted! Btw, I bought it from the vtac dealership and they told me we don't have technical support, you need to talk to the store where you bought it!
