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.

These wifi smoke detectors go offline about every month to six weeks for no apparent reason. None of my other wifi connected devices do this. Clearly something wrong with the software. The only way to get them back online is to uninstall them and to reinstall them, which really defeats the purpose of this detector, which was specifically purchased for the arm in the top of my 15-foot vaulted ceilings. If I wanted to manually access this alarm I would have left my non-wifi alarm up there. I am very dissatisfied with the performance of these wifi-enable smoke alarms.

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

With all the current technology it doesn't make any sense to install normal smoke detectors. These are perfect when you are not in home/office. If you think they are a little bit expensive just remember what you are trying to protect with them.

The media could not be loaded. Yo compre 6 detectores de humo y acá comparto mis comentarios.1- Uso de la AppPara 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.

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.

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.
