Broadlink RM4 pro & Nexa Dimmer 433

Hi

I have a Broadlink RM4 pro that I have managed to learn RF commands for my sun blinds without too much issues.

I have not however successfully got it to learn commands for my Nexa dimmer. The dimmer is self learning type, which I suspect has something to do with my issues.
Learning commands from the physical RF remote that today controls the dimmer does nothing. It seems like I get different codes each time. I have tried with alternative: true without luck.

What special commands etc to I need to do to get this combo to work?

Cheers!

Is the Nexa dimmer the problem? If I understand you correctly, you have already taught it to respond to the RF commands from the remote, and now you need to teach the Broadlink to send the commands. What kind of remote is it?
