works really well apart from a minor lag
easy to install, works as intended however there is quite a bit of lag between the door opening and the alarm going off

WiFi Door Sensor Window Detector
WiFi Door Sensor Window Detector – I like that is easy to use and install on doors, windows for homes and shops.It will use the Smart Life app to send you notifications via Wi-fi 2.4Ghz.3M adhesive tape included.It works well, I definitely recommend.

Good, slight delay
Pleased with this. I have it set up to sync to my Home Assistant server so I can use integrations with it.It’s a relatively easy set up, seems to work well, although there’s a little bit of latency, and works well with Home Assistant, so I don’t have to rely on the app / proprietary integrations. Battery looks like it will last quite a while.

Not really very good sorry.
Work for a day or too before not connected.Alarm takes 2-3mins to trigger, and on a locked phones don’t light up or buzz, there’s just a messsage notification, that’s it. So if you’re distracted you’re not going to see.NOW, if the APP is Open you get a blarring alarm and you know the doors been opened.So if you were wanting to use this to track if a kid leaves the house, or if there’s a break in, it’s no good.If you want to stick one on a liquor cabinet / beer fridge so you know if someones been sneaking a drink.. well that’ll work.Support was, well useless. I managed to reset one and get it working, but the 2nd never did, regardless of the battery switch…. Support was adament a new battery would fix it, the things been up 2-3 weeks tops, if the batterys dead on a door I barely ever use in 2-3 weeks then the products no good either way.

Good value
Well, luckily you can use it with the Smart Life App, so there’s no need for registration. Beyond that, it’s just a very sophisticated door checker for paranoid people. Of course it has other, more creative uses for automation, but on it’s own, it offers very little.

Customer Review –
Works but not as good as it should be in my opinion (Senckit)
If you have Smart Home app already, it is easy to add the door sensor automatically. Or you can add it manually for the list.That’s the easy bit.What made it most painful for me, is the positioning of the two elements.If you don’t do it correctly, you end up with a barrage of notifications coming up one after another and annoying sound. And even if you do position it correctly, it doesn’t react to it immediately – I thought positioning was still off so tinkered more with it.You have options to switch it off – there are options for open, closed and battery level which you can toggle.Now, as some others noticed, the response id delayed. I measure it with a stopwatch and it’s approximately 5-6 seconds delay from opening the door to notification showing up on my phone and 1-2 more seconds before the alarm sounds.Is it good response time? Not for some.Will I be using it? It’s a no from me.If you have a small shop or any other place that anyone can come in, it could be good for you. But as I said, response time is slower than it should be I think.

Super bonne durée de la pile (après 6 mois elle est toujours au maximum) facile à installer vis à vis de l’appli Smart Life. Ãa fait le job.

Me han encantado. Despues de llenar la casa de productos de domotica y probar de todos los tipos, estos me parecen de quitarse el sombrero. 6 estrellas les daria, que buena compra.Cogi el pack de 4. y me salian creo que a poco mas de 15eur por cada uno, que era encima el mejor precio que vi.Luego vienen con todo lo necesario, incluida la pila y la cinta doble cara si los quieres pegar. que encima pega bien, o tornillos si lo prefieres asi. Nosotros los pegamos y muy bien.Ademas se configuran super facil, con la app standard Smart Life, y tienen un alcance WiFi a la par que un movil de alta gama. Y al estar en esa app, facil ponerlo con tu asistente de voz y usarlos para rutinas y, por supuesto, para alertarte de seguridad.Por ponerles una pega, las traduciones y estados son poco consistentes. En una parte pone apagado, que es puerta cerrada, cuando en otra parte usa puerta abierta o encendido. Y algp similar cin los colores. Pero bueno, una vez que lo entiendes, pues ya está.Super recomendado.

Contrairement aux commandes sur dâautres sites de RDC ce modèle offre des possibilités de paramètre étendu⦠les aux autres vous serez limité à un On/Off ! Ici laps de temps dâouverture et fermeture commande lié à un autre appareil de chauffage ou climatisation par exemple. Le tout par SmartLife nickel !

Funziona benissimo, nessun tipo di problema e l’ho montato già da parecchi mesi, bisogna ricordarsi che ogni 3/4 mesi la batteria si scarica e bisogna cambiarla.
