Somfy Overkiz Outside Heater No Button available to push on/off

Hello, I just added my somfy Screen, Pergola and Heater to Home Assistant via Overkiz.
Pergola and Screen working perfectly. Only the heater is not really working. No switch entity available. Just two entities for Identifying.
If I push this than the heater goes on and off 3 times. How can I create just a switch to switch on and Off the heater? Thanks
