Is there a way to have Rachio do variable watering times, in a similar way as what Hydrawise does? With Flex Daily Rachio controls which day to water, but the time it waters remains the same. For a specific application I’m looking to eventually water every day, but have the watering time vary due to ET
Not do I know of. Flex daily will fill and try to maintain a particular amount based on zone settings, I guess you probably know this if you are using it.
There is heat/cool boost. But adjusting watering times will only push furthur down (Heat boost) or make the next date sooner (Cool Boost). I did a post recently asking for a feature request on this and explained my take in that post. Basically, you will need to adjust crop coefficient during heat waves, this will potentially make waterings much closer during such.
