I am Liza remote working, but need a way to passtrough blinds to DiyHUE

For those, who are interested: With the help of DiyHUE, I was able to pair the Liza remote (liza: steuerung für tv, musik und licht).

Although, lights are working, I could not manage to integrate Blinds (IKEA ZigBee, paired to Sky Connect in HomeAssistant).
