This RF Bridge 433 can convert most of the 433.92MHz RF Remotes into WiFi wireless. By adding the RF wireless Bridge to iOS/Android App eWeLink WiFi wirelessly, you can add up to four 1-4 buttons 433.92MHz Wireless RF Remotes or 433.92MHz sensors to the RF Bridge device. After pairing the 433Mhz RF Remote buttons with 433Mhz RF controlled devices, you can directly control maximum 16 RF controlled devices on the App through WiFi/2/3/4G network.

It can be used for most of the 433.92MHz RF Remote controlled products, like RF controlled switch, RF controlled socket, RF controlled bulb, RF controlled door opener, etc. You can set totally 8 schedule/countdown/loop timers to turn on/off the RF controlled products.

Even more exciting is that it will work with the 433.92MHz door magnetic sensor, 433.92MHz human body IR sensor, and more other 433.92MHz sensors to realize security alarm, and allowing you to DIY smart scenes. Note that the alarm push only comes in the owner's account, those users being shared can't view the alarm push.

PIR2 is a 433.92MHz RF PIR motion sensor that for human detection. The motion detector can work with the Sonoff RF Bridge 433, providing human detected alarm message push to your phone.

DW1 is a door and window alarm sensor. The door alarms can work with Sonoff RF Bridge 433. DW1 door alarm sensor detects the opening status and immediately sends alarm notification message to the app.
