Broadlink RM4 Pro RF Command

[thuva]

I was able to configure RM4 Pro following this tutorial:

Broadlink RM4 Pro: Home Assistant & Node-RED setup - part 2

I am using the app “BroadLink” and not ihc or e-control. I tested with IR command (tv remote). It works.

Now I want to learn RF command, but donno how to do. In this video he explains how to do:

Integrate Broadlink RM Pro into Home Assistant - Control IR and RF

but with e-control app. In Broadlink app donno how to create a simple “RF socket” something.

Any help how to do with “BroadLink” app to sweep the frequency?
