X-Sense Wi-Fi Smoke Detector, Wireless Smart Fire Smoke Detector with Replaceable Lithium Battery & Silence Button, Auto Self-Check Function, XS01-WT, Pack of 3

First the small size is a nice feature. I purchased these because I wanted a detector in the basement. But since there is no one down in the basement most of the time I wanted to be sure we would hear an alert. That's where the Wi-Fi detector came in, I figured even if it wasn't heard we would be alerted on our smart devices. The connection isn't the greatest for WiFi in there basement. But with the added configuration setting if the device losses connection it will also alert you after a few minutes on your smart devices that the wifi connection has been lost. That way you are safe knowing the device is working as expected, and you can feel safe knowing you will be alerted if that changes or smoke is detected.It might be small in size but it sure isn't a small cheap speaker, that thing is very loud! If you test it be sure to let people in your house know your testing, because even the test beeps are loud and someone will think there is a problem :)Hopefully I will never need to be alerted, but I do feel safer with the Wi-Fi connection. Just an added alert in case we don't hear the basement alert signal upstairs on second floor.As far as battery life that I won't know hopefully for awhile, but it is replaceable and will alert you on low battery to your smart devices as well. It displays the battery level in the application along with any alerts or charges in a log.Might do some testing later, if I do I'll update this review.

Setup is little complicated but if you slow down and read the instructions it's actually not bad. You have to activate them all at the same time since they are all interconnected wirelessly. They self check and send a notification to your phone weekly. Would definitely recommend these.

Will not work on 5G, so be sure your router has a 2.4 G output.

The interface on these is bizarre, to say the least. Once the alarm is triggered, if you silence the device from the app (that's a big selling point so you don't have to get a ladder out) then the device does not come out of the silence mode. You can set the "silence" slider to off, but the red light keeps blinking and the device moves back to silenced when you check it in the app.That's bizarre and makes these things worthless, especially at that high of a price for a photoelectric smoke detector.Also, when testing with a smoldering pot, this alarm took much too long to detect the smoke. I think it's because of the tight mesh design that "looks cool" but inhibits air movement through the photoelectric sensor. Dumb. When it comes to warning devices, SOONER is better.

I was looking for extra sense of security when I'm away at work and my dogs are home alone. These deliver! Easy to hookup to wifi and use check in to ensure they're functioning properly.

The media could not be loaded.  Yo compre 6 detectores de humo y acá comparto mis comentarios.1- Uso de la App Para configurar cada uno de los sensores, debe de oprimir el boton de test por unos 3 segundos hasta que quede parpadeando. Abre la app en Agregar dispositivo y selecciona "Sensor de Protección" y luego Alarma(Wi-Fi). Desde ahí sigue los pasos y detecta los dispositivos en forma facil.Un herramienta util seria que desde la app uno active algun sensor, pero no da esa opcion.Otra herramienta es crear un escenario para que cuando un dispositivo se active los demás tambien (Ver abajo)2- InstalacionYo use la cinta doble pega que viene en cada sensor en lugar de los spanders y tornillos. Es mas conveniente.3- Detección de humosEsta es la parte en donde deja que desear el desempeño de los sensores. Como pueden ver en el video, para que la alarma se active, cuesta bastante, pero se activa.Lo que hubiese deseado es que si un dispositivo se activa, los otros 5 se activen tambien, pero esto no es así. Eso porque si estamos durmiendo y hay un evento, la idea es que el sensor del dormitorio se active a pesar que sea otro sensor.Estuve tratando de crear un escenario en el app para que cuando una alarma se active las otras tambien, pero no da esas opciones.Lo "bueno" es que al dormir con el celular y el ipad a la par, estos le avisan a uno que se activó uno de los dispositivos pero no se mantiene la alarma para que lo despierte en forma definitiva por aquello de la gente con sueño pesado.Vale la pena, pero al final le faltan muchas funciones para poder ponerle 5 estrellas.Es compatible con Alexa y uno hubiese pensado que si un dispositivo se activa, Alexa le notifica de inmediato para evacuar, pero no. Así que le falta en esto también.

If you want this fire alarm to connect the you have to have 2.4ghz WiFi and if you have both you will have to turn off the 5ghz while you set up the alarm for it to connect.

Great product very easy to set up.
