I've set up all my rooms in Google Home to match EvoHome. What commands can I shout at my phone because I cannot find a reference online... I see "set temperature to X" but the whole point is I have all these zones.

I've spent time trying different things but keep getting "that mode isn't available". As with most of these things it's typically quicker to walk down 2 flights of stairs and turn the knob than to figure out how to do it the 'easy way'!
