A few items that would help improve the Alexa integration.
Allow creation of a named ‘Group’ of zones. I could combine my 5 backyard zones into one ‘Backyard’.
e.g. : ‘Alexa, water the back yard for 5 minutes’ will water all backyard zones.
Enable a default watering time for each zone & group.
e.g. ‘Alexa, water the back yard’.
Allow multiple aliases for zones & groups. I would set this new group Backyard to have an alias ‘behind the house’.
e.g. “Alexa, water behind the house”, & “Alexa, water out back”, & “Alexa, water the back yard” could all do the same thing.
Work with Amazon on getting rid of “Tell Rachio to…”. Yeah, I know this one is a long-shot.
