ST Sensibo automation not working

Hi all! I currently have 2x Sensibo AC wifi controllers that are linked to both ST and my google home. These work find when operating through the ST app (Android).
The issue I have is that if I create an automation that is linked to a ST sensor, whilst it does seem to trigger the Sensibo, it doesn’t actually turn it on.

Eg. Turn Lounge AC ‘on’, then front door (sensor) opens. The automation works and I can see the Sensibo light up and beep, but the AC doesn’t seem to action anything.

Again, I go into the ST app and turn the AC on, it works right away.

Any ideas/suggestions? I really want to have this automation work from a temp of a sensor upstairs where my baby is sleeping.

Thanks!
