So far, I am extremely pleased with my Rachio. And my lawn looks great and I'm quite a bit down on water consumption compared to last year. BUT... not having soil moisture sensors, much of the watering (I use Flex Daily) is still obviously guesswork based on conditions. And while I think it's doing great, I'm also seeing mushrooms in 2 zones. So, my thought was, if you simply added a "Hey, back off a bit on zone X" button, that would allow us to still use the Flex Daily for max water savings, but also slowly train the system a bit. Or, getting more complex, but still probably easy to build in, the ability to add conditions, like:
Zone X looks great but I'm getting (weeds, bare spots, mushrooms, etc)
So the system could make mild adjustments. Maybe if it were going to water that zone for 13 minutes and I said it's got mushrooms, maybe for the next 2 weeks, it changes '13' to '11' - but leaves everything else alone?
