Sonoff RF bridge doesn't learn remote buttons, always times out

I'm trying to get the Sonoff Bridge to learn remote codes from this remote APA3-1500R. This remote is operating at 433.92MHz


The bridge goes into learning mode, I hear a beep and the red led is flashing. However, I try many times to learn different buttons, but it always fails after one minute with a timeout error.


This way the bridge is useless to me. I'm following the instructions closely. Is there a way to fix this? Can you release a firmware update?


Thanks,

Johan

Existem inúmeros fabricantes de controles remotos RF no Brasil. Como eu já disse, os mais modernos usam código criptografado para maior segurança. Desse tipo é impossível usá-lo com um Arduino.

Mas os controles mais antigos tinham pouca "inteligência". Esses transmitem códigos pré-gravados pelo fabricante, mas que não se alteram. Assim é possível usa-los com Arduino.

Vou desvendar então, um controle antigo que usa o Chip da Holtek, o HT6P20B. Ele transmite 24 bits codificados. Pode ser programado uma vez somente, pelo fabricante do controle remoto.

Same problem here.  I have tried 5 diferents remotes controls

This sounded like such an amazing device but your posts make it seem like a failure. I was hoping to use it to control my fireplace via Alexa, but I doubt it will recognise the commands. I might still buy it via Amazon Prime, as I know I will be able to return it if not. The trouble is, how are we meant to know what kind of coding our devices use? I can't even find the frequency that my fireplace remote uses, nevermind the coding.
O meu Sonoff Bridge está do mesmo jeito que chegou e pelo visto vai pro lixo! Testei diversos controles 433mhz e nenhum funciona. O pior é que o suporte do equipamento nem se pronúncia com alguma ajuda. O aparelho NÃO FUNCIONA!

I think our mistake is assuming the bridge can be used with any 433Mhz remote, when it seems to be intended to mainly act as a bridge to enable wifi control of Sonoff RF devices that otherwise use their RF remotes (eg https://www.itead.cc/wireless-4-buttons-push-cover-remote-controller.html). The bridge *might* work with some other 433Mhz remotes, but the range of remote types is fairly limited. Options are either to 'hack' the bridge with different firmware, or use something else like a Broadlink RM Pro (which is what I've done).

Does hacking the firmware mean it can learn any commands, or is it just a better interface? Also do you lose Alexa and Google home integration?

See here for an example: http://tinkerman.cat/hacking-sonoff-rf-bridge-433/


The device is an ESP8266 so you can completely reprogram it to do whatever you want. You do, however, need to be willing to learn how to program.....

....and here's code written by someone who is trying to get the thing to support more devices!

Será que um leigo no assunto, um simples usuário como eu poderia adquirir um produto desse?  ou esse dispositivo é feito só para especialista?  

It's not entirely clear whether simply flashing ESPurna would mean this now supports far more RF devices/commands or not? I'm not sure what the use of the second link is if ESPurna already supports various devices.


I can program and I'm comfortable in Linux, but I don't have an arduino programmer, I'd have to look into that.

Same problem here. 

I tried different remote controls including an original itead RF control. I tried to change the firmware but still does not learn the RF signal. I think it's simply faulty.
I ended up flashing espurna, but no luck with learning the codes I need. I have a Mertik Maxitrol remote for a gas fire and the bridge can't pick up any of the commands. It gives out a beep to say it's trying to learn, but doesn't pick anything up.

o suporte ITEAD poderia se pronunciar com alguma resposta que possa resolver esse problema?


Pelo visto comprei um produto que não funciona!

I had the same problem! - Could not copy my different 433 Mhz remotes to Sonoff RF Bridge. It just timed out. The trick is to program a 4 button remote (see pict) with the remotes, which is not accepted by the Sonoff Bridge. After that, you use the 4 button remote to program the Sonoff Bridge, which now accepts the codes.

Clear this by pushing the two square button at the same time.

So the 4 button remote can learn codes that the bridge cannot? And then the bridge can learn from the remote? Seems unlikely to work, but worth a shot for $2.
