I just set up my first schedule in the Rachio software. I want it to have complete freedom to make the best watering decisions for my lawn and trees so I set up a Flex Daily schedule and basically clicked all of the settings that put it on auto pilot. I let it pick the watering days, I enable full Weather Intelligence, I enabled Smart Cycle and in general just picked all of the recommended settings for the schedule. My curiosity is this: if Rachio knows the type of plant its watering and it knows my soil type and it knows how hot it has been and I’ve basically told it to make all of the decisions on how to water my lawn on its own, why oh why is it asking me to set a duration? I thought the whole point was that I didn’t know how long to water my lawn? Sure it comes in with a recommended duration amount, but if it was confident that its recommended amount was right, why does it drop me on that screen and ask me to check that the time limits are good?
Should I just use the recommended amounts? I used to water my lawn 3x a week for 15 min each station. My grass was green and didn’t grow too fast (don’t want to have to mow weekly). However, Rachio wanted to water each station for 28 min when it ran the first time. I panicked because I wasn’t sure how often it was going to water so I adjusted its run time down to 15 minutes per station, but am I actually wasting water and money by not letting it do its recommended 28 min run time? It looks like with my 15 min duration setting it’s watering every three days currently.
I appreciate any light someone can shed on this issue. Oh, and I’m on a Gen 3 controller.
