Sensibo Sky integration won't turn on AC - everything else works fine

So i successfully installed a sensibo sky unit using sensibo integration, everything works fine and i can control every aspect of my heather, except HA is unable to turn the unit on, and i have no clue where to start looking. This works fine using the app so sensibo has the right codes so guess there is an issue with command signaling or command reference in HA integration between Sensibo and HA.

Any ideas to get me moving forwards or where to look?

Regards

some further investigation shows that it’s the default thermostat that has this problem, creating a custom on/off switch operates the AC/heater correctly
