Smart Sprinkler

We have been having trouble with our landscaping not getting properly watered. We had a 15 year old sprinkler controller, and I was afraid it would quit working while we are gone on vacation. I justified that it would be cheaper to buy a new smart sprinkler controller than to replace all of our new landscaping.
I bought the Rachio 3 system for about $275 (including weatherproof enclosure). I read lots of reviews and it was rated the best. I had to dig up some power conduit and valve wiring to connect it up properly, which was a lot of work, but I am retired and have no excuse for not taking the time to do it right. It is all hooked up now and working fine. I can ask Siri to run the back yard sprinkler for 5 minutes and like magic it does. It also gathers weather data from all the stations in the vicinity and computes the weather at our house to within a 36 foot error. That sounds pretty amazing, but we live in Southern California, the weather never changes here, so it is probably not of that much benefit. Well at least I can go traveling and know my grass will still be green when I get back.
