Description: This RF Bridge can convert most of the 433MHz RF Remotes into WiFi wirele.By adding the RF wirele Bridge to iOS/Android App eWeLink WiFi wirelely,you can add up to four 1-4 buttons 433MHz Wirele RF Remotes to the RF Bridge device.After pairing the RF Remote buttons with 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 door magnetic sensor, human body IR sensor and more other sensors to realize security alarm, and allowing you to DIY smart scenes.Note 1:The receiving supports fixed code 433 frequency: PT2260, PT2262, PT2264, EV1527.Not support to learn rolling code and dynamic code.Note 2:Timer is not supported in current App versions, but soon we'll support it.iOS App doesn't support to add this product, but it will be supported in App V2.5.0.You can't see device status changes in the App. As A "Bridge" to Other Protocol Device Traditional 433MHz Remote Control Devices, Instantly Become Smart Note: The receiving supports fixed codes 433 frequency, like EV1527, PT2260, PT2262, PT2264, etc. Not support to learn rolling codes. A Button for A Scenario Create a scene you like. Simply pre the remote control button to trigger WiFi or ZigBee devices in eWeLink to enter a scene. Control All Devices Simultaneously Once the RF BridgeR2 has succefully learned common remotes, you can use the remotes to control lots of devices in a time. Create Smart Scenes with 433MHz Sensor Multiple Timer Way Such like Specified time/ Countdown/ Loop execution.
