To learn a new code click LEARN, the Sonoff RFBridge will beep, then press a button on the remote, the RFBridge will then double beep and the new code should show up. If the device double beeps but the code does not update it has not been properly learnt. Keep trying.
Modify or create new codes manually (all codes must be 18 characters long) and then click SAVE to store them in the device memory. If your controlled device uses the same code to switch ON and OFF, learn the code with the ON button and copy paste it to the OFF input box, then click SAVE on the last one to store the value.
Delete any code clicking the FORGET button.
