First of all, welcome to Team Rachio!
We do encourage users to do deeper and less frequent waterings, as this promotes a healthier and more drought resistant landscape! However, we have a couple different options in getting there.
Option one would be to jump into our Flex scheduling. Flex requires a bit of investigation and work to tune in at first, but we have large group of users here that have been really successful with it, and it is the best way to acheive deep and infrequent waterings. Flex works off this idea that each of your zones has a “gas tank”, which we track so we only water when you gas tank has hit a certain level. However, there are some important things to note with flex. First of all, like I mentioned, it takes a bit of work in the beginning. Second, be prepared for much longer waterings than you are were used to in the past. They will be much less frequent, but often that initial duration can scare people off! And third, there is less consistency with flex. Zones will only run when needed, so a different group of zones can run on any allowed day. This is a deal breaker for some users.
The other approach we can take is a fixed schedule aiming to put down the 1" a week you mentioned! If we go that route, I can walk you through a process on how to determine how much your system is putting down, then we can set up some intelligence to skip based on weather, so you can stick to that 1" a week and skip if Mother Nature is taking care of it!
One last note- either of these situations can be used with our smart cycle feature, which is what breaks up your schedule like you mentioned. Let me know how you would like to proceed!
