Description:
This RF Bridge 433 can convert most of the 433MHz 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 433MHz Wireless RF Remotes or 433MHz 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 433MHz RF Remote controlled products, like RF controlled switch, RF controlled socket, RF controlled bulb, RF controlled door opener, etc.

Even more exciting is that it will work with 433MHz door magnetic sensor, 433MHz human body IR sensor, and more other 433MHz sensors to realize security alarm, and allowing you to DIY smart scenes. This model supports Amazon Alexa and Google Home voice control.

PIR is a 433MHz 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.

Freestanding/wireless smoke detection alarm 360° omnidirectional detection high sensitivity alarm; When detecting the smoke generated in the early stage of the fire, the wireless smoke detector immediately issues an independent sound and light alarm alarm prompt and sends 433 signals to the fire main engine, and the wireless transmission distance is 300 meters; the built-in super volume alarm siren and overhead light guide column.
Alert and warn people stay far away from danger field when it detected smoke.

Note 1: The receiving supports fixed code 433 frequency, like PT2260, PT2262, PT2264, EV1527, etc.
Not support to learn rolling code and dynamic code
You can't see device status changes in the App.

Note 2:What's new on Android & iOS 2.5.0 and higher versions?
Scheduled/countdown timers are supported.
iOS App supports to add this product.
433MHz RF curtain switch and RF alarm are supported.
