Same here. It’s a really great product, and can you keep you busy tinkering at the beginning. Set up ‘fixed’ schedules for now, then pick one and start to dig into the details on Flex Daily. There’s a fair amount to digest, but I found it a fun learning process, and in the end I ended up saving a ton of money with optimized irrigation. One of the best parts is that I don’t have to muck with the controller as temps change from 120F in the summer to frost warnings in the winter. It just figures it out. Again, you have to take some time tinkering to get there but this community is awesome for that. You’ll get a ton of help if you want it.
These are my personal recommendations, but there are a lot of other great resources to get started on in this community, and in the Rachio support articles.
