Hello, I recently purchased a Rachio 1st Gen 16ZULW, and I will be replacing a Rainbird SST1200O. The Rainbird came with a “weather sensor”, which adjusted watering based on measured temperature, precipitation and a historical (pre-programmed) weather database. I’ve used the Rainbird controller for a couple of years now and have found the optimal settings for each station through trial and error. The Rainbird setting for each station is simply the necessary weekly schedule based on the average warmest period of the year. The Rainbird controller would then adjust watering by percentage (higher and lower watering times based on this baseline value), based on the measured weather. I was hoping I could directly translate these settings (i.e. baseline weekly watering schedule) to the new Rachio controller, with watering time adjustments based on actual & forecast weather, but it appears to be more complicated.
My question: How can I use my Rainbird controller settings to setup my Rachio controller? I know how much water each zone needs during the warmest part of the year, so I’ve tried to setup my zones in Rachio to achieve a “Flexible Daily” schedule with a “Duration” equal to what was used in the Rainbird. To accomplish this, I’ve tried different combinations of “crop” and “sprinkler heads”. However, I don’t know what “100% Duration” means for the Rachio (i.e. is that the weekly amount, or per-watering amount; warmest part of the year?).
Is there a better way to setup the Rachio by using the information from my Rainbird without starting over with trial & error?
