Works great
I modified these door switches to use for my washer and dryer status. They have a large battery so they should operate a long time as many of these Wi-Fi devices use a small coin size battery and don’t last very long on battery power. They were easy to setup and pair. Works with smart life and Alexa. I have a routine with Alexa that announces when my washer or dryer has stopped running. Recommended

Not working as expected
The devices & app on phone would not connect or stay connected. When it disconnected from phone I had no way to be aware so security was not there. Even when it appeared connected it did not give proper notification. It was advertised as working with Google or alexa type devices and was not able to connect them. Very disappointed.

Window defaults
Um these was ok only because it seemed to come off windows at time and alarm did work as performed.

Easy to setup
Easy to use and set up. Only took few minutes, this device works every single time without any issues. I first got 4 pack to see if it was as good as the details/features, after having it for several month it was working perfectly. In ordered more. Price was feasible as well.

Doesn’t function with Alexa devices
This does not connect to Alexa in any way. Can’t pair it with lights for routines, can’t change any settings in the alexa app. The best it does is notify me from the device app when a door opens and closes. The device app, NOT Alexa. False advertising! do not buy!

Easy to set up, works well with alexa
I got these to replace the chimes on my front and back doors as I have an infant at home and wanted to be able to control the volume of any alert. They work great, alert on Alexa within a second or two of the door opening and don’t wake my kiddo up.

works as intended
not much to say, day one it works out of the box using the “smart life” app to manage it.i wish these types of devices didn’t require an app but it’s alexa integration seems to just be done through the app and not the device

Started great but then…….
Installed as garage door sensors. Two on the single roll up doors and one on the man entry door. Installed a mesh network satellite in garage for perfect Wi-Fi in that location. Set man door to give push notifications when opened. I didn’t set alarms on the roll ups doors but added them all to Alexa. Made a group called garage doors. Then you could ask ” Alexa are garage doors open?” Alexa would then tell you if they were not closed! Joy Joy no more getting dressed to check if I closed the doors! All working great for about 3 weeks. But then one day I walked in the side door and my phone was quiet, no message the door had been opened. Check both its app and Alexa, both said connected. Opened garage doors and still said closed. Checked the satellite connection and Wi-Fi was good. Have been getting problems ever since so changing to a better system. Only takes then not working once for losing a ton of things in a break in. Take it or leave it that’s my 2 cents worth.

Me sirve para saber si alguien abre una puerta o ventana de la casa, envía un aviso al celular con alarma cuando se abre y avisa cuando cierran
Valeria –
No eran lo que necesitaba. Las alertando celular se pierden entre tanta notificación y tardan en aparecer . No emiten sonido en físico.

No funciona con Alexa ni con la app, para que envíe alertas por mensaje o correo debes pagar en la app el servicio, es un robo! Ahí está nada más de adorno en mi puerta sin hacer su función
