I understand you abandoned the idea that your device managing IR / RF can do it really. I did not. I already have a Broadlink, but I don’t see the point to keep several devices consuming energy while they could/should do the same thing.
So thank you for your answer, but please, stop proposing to use Broadlink or Harmony. If I’m here it’s to find a way to get Homey doing the full job, not to reproduce what I already have in place currently.
The Homey is technically able to learn IR / RF on short periods. That’s what is used when you are in Homey developper console. But this API is not available for use in applications (which could for instance listen for signals just after creation and memorize to re-send when triggered. It would listen only in the first second of the configuration).
It seems there is a page about such API here:
But it sends to a 404 page (deleted page ?)
