some devices lose connectivity to the bridge randomly despite being next to the bridge, so it's not an issue with the distance or signal. Had to either restart the bridge or to remove/add the device.

If you want to connect to IFTTT you need to pay a yearly subscription.

I am using this device to monitor my room temperature. If a certain level is reached, thanks to the scene i am triggering the air fan to get some cold weather.

IFTTT non fruibile se non pagando un abbondamento dell'app del sensore
Reviewed in Italy 🇮🇹 on 12 January 2021Connectivity Technology: RF 433MHZConfiguration: DW2 RFVerified Purchase
La trasparenza è importante e scrivere che un prodotto è utilizzabile con IFTTT lascia ben intendere che acquistandolo si potrà fruire senza dover fare altro e invece no, quando si configura il sensore e si prova a collegare l'account con IFTTT l'app del sensore spiega che per usare IFTTT occorre pagare un abbonamento annuale (oltre a quello di IFTTT). E allora no, rimandato indietro e acquistato un prodotto concorrente.
Trovo scorretto giocare sul fraintendimento pur di vendere.

Failed after 42 days! UPDATE! All okay again now!
Reviewed in the United Kingdom 🇬🇧 on 1 February 2023Connectivity Technology: RF 433MHZConfiguration: DW2 RFVerified Purchase
This Sonoff door/window switch worked fine initially but this morning, 42 days after I installed it, it is completely dead.
No LED light, flashing or on solid!
I replaced the batteries but still no good.
I have now found out that the Returns Policy is for up to 30 days!
So it didn't last even 2 weeks past the Returns cut-off period!
If I order another one I am worried about how long that will last!
Has anyone else had this problem or have I just been unlucky?
UPDATE.
Replaced the battery (again) and re-paired it - and it works again!
Not sure what the problem was, but all okay now and it is behaving itself perfectly!
Since buying this one I have bought another one and they are both working fine.
One turns on a light in the understairs cupboard and the second one gives me an audible warning and flashes some lights (via Alexa) that the outer front door has been opened.
I might get another one for my back door! :)

Works well but......
Reviewed in the United Kingdom 🇬🇧 on 12 October 2022Connectivity Technology: RF 433MHZConfiguration: DW2 RFVerified Purchase
The sensor does a good job, easy to install and setup. Works well and keeps a log of the events. Easy to integrate with Alexa too. BUT..... and it's a big BUT.... the battery life is awful. I have tried a variety of battery types and non of them work for anymore than about 10 days. The door is opened probably about 4 times a day so not what I would call heavy usage? It's a shame because in every other way it's a good sensor

These work fantastic

If, like me, you have kids that leave the freezer open, and you go to it the next day and find all your expensive meats thawed out, it drives me crazy I have to throw all that meat in the bin. Well no more wasted meat!!!
I like this because.....
- Easy to install
- Notifies me via notification
- Simple and effective
- Low cost
- Two AAA batteries and install within seconds. I use amazon basics researchable batteries, these are great too.
Hope you like it like me :) Well done sonoff, big fan!

Ohne W-Lan Fachwissen manchmal schwierig einzurichten.
Reviewed in Germany 🇩🇪 on 25 November 2020Connectivity Technology: RF 433MHZConfiguration: DW2 RFVerified Purchase
Allen die es nicht geschafft haben den Türsensor mit ihrem Router zu verbinden sollten in ihrem Router nachschauen ob der so eingestellt ist das er mit dem WI-FI Standart IEEE 802.11.b. zusammen arbeitet ( siehe Bild Fritz Box.)
Bei mir konnte ich erst eine Verbindung herstellen als ich das in meinem Router eingestellt hatte, da die Voreinstellung nur mit dem Standart IEEE 802.11.n+g eingestellt war.
Wichtig ist auch zu wissen daß sich der Sensor nicht mit dem Smartphone verbindet sondern mit eurem W-Lan Netzwerk. Das Smartphone mit der Bluetooth Verbindung + eWeLink App überträgt nur alle wichtigen Einstellungen von eurem W-Lan Router an den Sensor so das der sich mit eurem Router verbinden kann.
Wenn man das alles beachtet funktioniert der Sensor tadellos, die W-Lan Anmeldung dauert dann nur Sekunden.
Da diese wichtigen Infos in der Anleitung nur unzureichend in Deutsch beschrieben sind habe ich einen Stern abgezogen.
