Works perfectly
Works perfectly. However you need to go to the settings > arming schedule > enable 24x7 . If you do not do that the device will get into sleep mode

Misleading Product- Door WiFi Sensor SONOFF
The sensor worked the first time and until today it frequently logs off network even though IT team attempted all solutions such as removing firewall, reserving IP over DHCP. I should have read product review before investing.Amazon pls remove this misleading product as it cannot be used for security purposes unless SONOFF seriously debug and provide a seamless cloud interface

Not a fan
The device worked every time i factory reset and re add it to the app. It will work for exactly 15 minutes and will go offline. Even if the device is pingable within the network and you have a good internet, this device will show you that it's offline! Not a fan. Please think twice before buying.
