RaspberryMatic falmot-c12 control

my plan is to be able to control the HmIP-FALMOT-C12 without using the real wall thermostats from HomematicIP, but with the ones from xiaomi (since I already have them)
I have an HmIP-RFUSB dongle, I installed CUxD in order to create some “fake” wall thermostats, but I can’t pair them with falmot-c12 outputs.

My wish would be to actually control the falmot-c12 within home assistant automations, if possible, something like the manual control with the real push buttons on the device.
But as far as I can see this can’t be done.

I am looking forward for some suggestions
Thank you

Hey There I have the same thought but with different thermostat. Do you figured something how to control FALMOT with Home Assistant?
Thank you.
