I have Gen1 controller and I also manage Gen2 controller of a family member. Today I was playing with Rachio app on my iPHone 5s. I have latest version installed.
I changed soil type from Loam to Silty Loam for a zone on my Gen1. Then I checked the watering time for that zone in my Flex schedule. It went up. That makes sense because Silty Loam absorbs water slowly compared to Loam.
Then on Gen2 controller, I did the same. I changed soil type from Loam to Silty Loam. I thought the time would go up. Instead it went down.
Is it a bug with Gen2 controller?
