New Google Home Integration - Only 3 commands?

I see that Rachio now has a proper google home integration and there is no more need to say “hey google, tell rachio to …”… but now… it seems theres literally 2 commands that work. hey google water the lawn, or hey google stop watering… it doesn’t work with specific zones for me. i can’t tell it how long. i can’t tell it about rain delays, or how long to go into delay. to go into or out of stand by mode… this integration seems flat out awful… whats the deal?
