I am amazed by the information here: The magic behind 433 and 868 MHz on Homey | Homey
However I could never make my Homey to learn and send 433MHz RF/IR commands. The (experimental) function to learn from a physical remote control just never worked for me. To solve that problem, I bought a Broadlink RM4 which works as a charm but unfortunately, it does not support 868MHz frequency.
I am now working to automate an internal door with a door driver from Hormann, which works with remote controls that operates at 868MHz, meaning that Broadlink cannot save my life once again.
Would be great if somehow I could use an app or virtual device in Homey that would trigger a 868MHz command to my door driver.
I see some topics ang GitHub projects about arduino using Homey built-in RF/IR hardware, but that is too much advanced for me, something more end-user friendly would be really appreciated.
