RF pairing to remote

I have my device connected and working but can not get it to link to any RF remote. I double tap the little switch as directed in the instructions but the led does not flash red. Any help appreciated.

11 people have this problem

I've opened the device and can confirm the RF module is present. There is a switch on the RF module, anyone know what this does?

Same problem, no solution :(

I've been told by developers that normal pairing should work or I can open the shell and press the 433MHz module for more than 2s to enter pairing mode. If this doesn't work it's a faulty device. Neither worker for mine so I got a refund. I'm now using the new Alexa skill so no need for the RF.

I've bought two Sonoff RF units with remotes. Both connect to WiFi ok, BUT neither pair with 433MHz remote using instructions provided. ie. press button twice rapidly to place in pairing mode. No red LED and no pairing. I tried pressing button on RF board for 2 sec (as per post by Mike), but still no result. I note there has been no response from ITEAD - this is very frustrating!! I have attached a photo of the unit I have. CAN SOMEONE FROM ITEAD PLEASE RESPOND.

I have the same problem and i did exactly the same you did. Now Im asking ebay seller to refund. Sonoff have a problem with this units and is not recognizing it.

I have the same problems with 2 sonoff RF, Its nor pair at all,  with the original remote that sale in Itead

same problem. 3 units Order #100077350


same problem.  Order # 100115356


I buy 7 unit and i was To buy more like 50 to 75 unit but the 7 unit not working with 433 mhz Press fast 3 time and it work érase press 2 time flash 1send signal nothing. ONe or 2 time record signal flash 3 or 4 time work on off 2 to 5 time and AFTER nothing TO BAD

You need to click very quickly 2 times to write. 3 times to erase from memory.


I believe we know all the procedure now.

Receivers do not work.

I tried with 5 different remote controls but nothing.

And iteadstudio continues to not respond.

It does not seem to me to behave correctly.

It does work guys but you have to use the correct remote(theirs) the receiver chip is nit universal so it will not work with any 433 RF remote. Hope this helps.
I but 7 unit and or ont working with my key gen but i find solution still waiting for new key gen and it working with arduino with 433mhz transiter vive somme more new later

I tried 5 different.

The remote controls work perfectly with the 4ch pro but are ignored by RF. 

You need to know what remote control are  compatible, or how to install a compatible receiver so you can use a single remote control. Externally they all look the same.
