They're not going to replace your lawn when it is destroyed by chinch bugs from being over stressed due to lack of water. Check irrigation bill usage. Even the Villages web site recommends 7200 gal/mo for a designer home.
How Much is Enough | TheVillagesWaterWisdom
I'm also a part timer. I have the b-hyve system and also have cameras. I have it set to every 3 days. I break it up on the days I water so it doesn't just run off. During the extreme heat and drought we're experiencing now, I'll add a manual cycle now and then. I was at about 4200 gals last month and I'll probably be 6-7000 this month in a Veranda so I'm within the guidelines. Before the new b-hyve controller I would hit 12000 gals in May and June. Too much run off and plenty of times it would water right before a rainy day. B-hyve uses forecast to adjust. Anyway, my advice is do what you need to do to save your lawn.
