I have an RM3 working perfectly well, with the device I am trying to control, so it’s nothing to do with learning codes.

This is the RM4:

I’m in the same boat as you, I just bought a RM4 Mini and RM Pro+. First thing I noticed is that I can’t even add the RM4 Mini to the IHC app, only the BroadLink app. While the RM Pro+ seems to work in both these apps.

Got the RM Pro+ working perfectly fine with HA, but I have no idea how to add the RM4 Mini to it…

I have created a FR for support for the RM4 to be added, can you add your vote to it?

I upvoted it, how did you learn your IR codes on your other Broadlink devices? I used the IHC app and the broadlink.learn service to learn RF codes for the RM Pro+. But RM4 Mini isn’t available in IHC, it’s only available in the “Broadlink” app.

I’m asking because I’m curious if you did (or if it’a possible to) use broadlink.learn with the Broadlink app instead of the IHC app.

I started learning codes - using broadlink.learn - then discovererd SmartIR, which has a library of codes for all the devices I needed included in the custom component.

8

You can also add your own learned codes to SmartIR if you want.

Uhm, I’ll look at it, but I read on a post in the HA community that the IR codes are not the same for a RM3 Mini and a RM Pro+. For example, if you learn an IR code on the RM3 Mini and then send it to a RM Pro+ it won’t work, and if you learn the same IR code on the RM Pro+ it looks different.

So I’m confused as to how a library of codes would help… I’ll probably make an attempt at getting RM4 Mini to work, but I’m not very confident about it at this point.

10

I can cornfirm that my IR codes learned by the RM Pro + are different then the same commands learned by the RM3 mini.

11

I want to buy RM4 Mini.
Does it work with HA now, or should I buy RM3 Mini instead?

12

Buy the RM3. Functionality is the same, RM4 is just smaller and more sleek and of course doesn’t work with HA yet.

I have the broadlink rm pro+ used the e-control app to backup the codes and copied them into a HA-switch. To turn my projector on and off and to get the screen roll up and down. I’m also using the smartIR component. For my ac. It works very well. I’m using the codes from smartIR library for my Toshiba Ac.

@Delicon The new RM3’s with new firmware also do not work in HA. You will need to try and find one with the old firmware.

15

True - I bought a RM3 recently thinking it would solve my problems… It didn’t.

I am now using a kludged together combination of webhooks and IFTTT to use my RM4.

16

I wish I asked before buying RM4 mini … any update on this? is it possible yet?

17

Still no progress. From what I understand it will require HA to use the cloud API rather than the Broadlink local API, and documentation for the cloud API is scant and confusing.

You could jump on Discord and you might get the attention of somone who knows more.

It should be ok soon!

The broadlink library used by home assistant has been updated (0.12 => 0.13). And there was a push request that has been merged in home-assistant to use this new version. => https://github.com/home-assistant/core/pull/33240

So the RM4 mini should work with the next upgrade !

Hi

I moved to HA version 108.1 (contain the Broadlink 0.13), but I can’t use the RM4 mini.
Has anyone succeeded already ?

Regards,
Alex.

I tested on the latest version as well. Still no joy.

Broadlink RM4 pro does not receive a signal using the broadlink.learn command, when you start the broadlink.learn service on the device, even the indicator does not light up to press a button and get the code in the Home Assistant. I read the comments that supposedly will be fixed in the next update, well, there were already 2 system updates.
