Well, in my case, I used about 40% more water compared to last year, and last year’s bill was high. Temps are the same as I operate a WeatherUnderground station at my house. (Rachio still can’t sync to these stations.)
I’d also like to stop it from watering on certain days, like the day the gardener comes for people who have that. For me, I’m the gardener, but I would like to exclude certain days when I know I’m mowing, etc.
Overall, I think it needs to be easier to set and then adjust to suit your needs from there.
