SmartWise DW2 is an enhanced version of Sonoff’s DW1 door/window sensor, and is compatible with Sonoff’s smart home product line. Comes in two parts: one to be fixed on the door / window, the other part to be attached the door/window-frame. When magnetic connection in-between is broken, an alert-signal is sent by the device.
Unlike Sonoff DW1, it can both detect and act as an action trigger in eWeLink for both opening and closing of the door or window. Oppening and closing sends different signals to RF Bridge (or relay switch with RF receiver), therefore two separate actions can be defined for opening and closing. (Such as: opening triggers light on, closing triggers light off.)
Connects to other Sonoff smart devices – e.g. lights, relay switches controlled by the sensor – with wireless, 433.92MHz RF (radio frequency) technology via Sonoff RF Bridge gateway, no need for wiring. Power supply is given by one CR2032 type 12V battery, (not included).
Via eWeLink app you can receive alert on any motion (opening, closing) to iOS/Android smartphone, easy to use as an alarm. When alert function is activated, alert is only sent to owner’s eWeLink account, alert cannot be sent to shared accounts.
