## Pairing a RF remote control
|
||||||
|
During programming a connection for R21 is needed in order to use a button press to ground GPIO0.
|
||||||
|
|
||||||
1. How to pair remote
|
To pair a RF remote control with the Sonoff RF it is important that there is NO connection made for R21.
|
||||||
2. How to see paired remotes (if possible)
|
|
||||||
3. how rf module interacts? is it using gpio14 or what?
|
User [gadjet](https://github.com/gadjet) installed a jumper in place of R21 allowing easy programming (jumper in), pairing (jumper out) and normal use (jumper out).
|
||||||
4. Can i use GPIO14 in sonoff rf? if yes, are all the options ok?

### Procedure
|
||||||
|
Pairing the iTead RF remote controller is the same as with the original iTead software:
|
||||||
|
- two short button presses will blink a red led shortly and start RF signal recognition. Three longer blinks signal RF reception.
|
||||||
|
- three short button presses will keep the red led on for some seconds and erase the known RF code.
|
||||||
|
|
||||||
|
I was unable to pair the Sonoff RF 434MHz receiver with my KaKu switches but the iTead provided remote control works just fine.
