433 MHz RF Sensor

Because the DW2-RF uses 433 MHz RF, you need a hub. The suitable hub from SONOFF is the RF BridgeR2. In addition, it is possible to pair it directly with certain SONOFF smart switches that support 433 MHz RF.

eWeLink

This sensor from SONOFF can be configured using your Android or iOS smartphone through the eWeLink app. The eWeLink app allows you to view the readings from your SONOFF sensors anywhere, including remotely. It is also possible to set up scenes that are automatically activated at certain values. With a scene, you can easily switch one or more devices on or off, for example you can switch on the light bulbs and close the blinds (if connected to SONOFF smart switches).
