From the picture, you can see the relations among the devices clearly. Firstly, you pair the 433MHz RF Remote controller with 433MHz device. Secondly, you add RF Bridge to App eWeLink. Thirdly, add the 433MHz RF Remote controller to RF Bridge via App, pair the buttons one by one. Then you can press the button on the App to turn on/off the 433MHz device remotely. One RF Bridge supports to add up to 4 RF Remote controllers.
