Direct Action (Smart Home) provides a simpler way for you to switch on/off and set particular settings just like a remote through voice control with shorter command line, where there is no need to mention "tell/ask Ambi Climate".

The Direct Action must follow the Google Home Smart Home framework, where Ambi Climate is treated like a thermostat so only Manual mode controls are allowed. You'll need to say a command for each setting you'd like to set.

For example, if you wanted the AC to switch on to Cool mode, temperature 24, say:

"OK Google, switch on {room}" - By default it will switch on to the mode and temperature it was last on in Manual mode. If it wasn't at Cool mode temperature 24, you'll have to follow up with a command

"Hey Google, change {room} to Cool"

"Okay Google, set the temperature in {room} to 24"

If you want to quickly switch back into Comfort mode through Home Assistant, you can give a feedback using the Custom Action, it would switch into Comfort mode
