Purchased for use using Smart Life app and Alexa. It works fine, can set it up to get alerts which I receive promptly, it tells me how long a door or window was open for and closed for. Not sure why others say they have to pay a subscription now as I don't. Located about 15ft from router. Suspect some of the complaints on here are from finger trouble.

Prodotto utile e buono. Peccato che non funzionava ma il venditore molto serio mi ha subito rimborsato e organizzato il ritiro.

So far, working better than expected. I recently converted the lights in my basement to smart lights. This is a utility basement for laundry and storage. So, just a few overhead leds conected to one light socket where I added a smart socket. I found it to be a pain to remember to ask Alexa to turn the lights on before heading down there so I was looking for a solution. This door sensor is perfect. I have it on the basement door leading from by kitchen. When I open the door, by the time I get down 2 or 3 stairs, it has already turned the lights on for me. When I come up and close the door, it shuts the lights off. Setting it up was pretty simple. I think that's partly because the SmartLife app works very well and typically finds any new device. But it connected on my first attempt and so far hasn't given me any issues. Honestly, I was worried because it didn't need a hub and the price was very good compared to similar options. I'm very pleased with this.

I bought this for my Electric garage door, wanted something to let me know if I've accidentally left it open. I eventually worked out how to set the scenes to remind me every 20 minutes if it was still open, and the app will also tell you if it is currently open or closed. So, it does the job I bought it for. Edit: Seems to have problems connecting to wifi and giving false readings, but can't return it apparently. Edit: Sadly, not doing it's job! Despite being only 3 metres from my Router, looses it's WiFi connection, and had massive delays or no notifications. Passed return date, but no use to me.
