Enhanced SmartWise RF DW2+ wireless door/window sensor (eWeLink compatible)

SmartWise DW2 is an improved version of Sonoff's DW1 door/window sensor and is compatible with Sonoff's range of smart devices. It consists of two parts: one attaches to the door/window, the other to the frame. When the magnetic connection between the two parts is broken, the device sends an alert signal.

Unlike the Sonoff DW1 the sensor can detect and trigger an action in the eWeLink app both when Opening as well as at closing doors or windows Opening and closing send different signals to the RF Bridge (or to a relay with an RF receiver), so a separate response can be defined for each action. (For example: opening turns the lights on, closing turns them off.)

Connects to other Sonoff smart devices - e.g. lights, relays - wirelessly via 433.92 MHz RF technology via Sonoff RF Bridge gateway, without the need for wiring. Powered by one 23A 12V battery (not included).

The eWeLink app allows you to receive an alert on your iOS/Android smartphone whenever movement is detected (opening, closing), making it easy to use as an alarm. When the notification function is activated, the alert is only sent to the owner's eWeLink account, not to shared accounts.

It supports the Smart Scenes function, so that a detected opening/closing of a door or window can trigger multiple Sonoff and SmartWise smart devices (smart switches, relays, smart sockets) via the eWeLink app.
