@Lngtrm1 Yeah, I agree. If I didn't already have the rain/freeze sensor, I'd probably be complaining about the same shortcoming.
Regarding my watering comment, it was only for grass. My grass seems to have already stopped growing. I watered yesterday (as you said, it was 92 after all), but am planning to stop watering my grass (but not shrubs) pretty soon. I also use a service called "watermyyard.org" from Texas A&M. They send out weekly watering recommendations and they're already saying 0" water for this week. They seem to lean more on the side of water conservation than Rachio does, so that's why I haven't cut the water off just yet. I'll keep an eye on Rachio and see what it wants to do. This will be my 1st winter with it (got it Spring 2017), so Rachio's winter watering is new territory for me.
So are you going to buy a rain/freeze sensor? My RFS-1000 has been quite good. My parents also have one that has run without problems, so there are two data points for you. Rachio installation is very easy and is done in about 1 minute.
