Just installed my Tempest weather station in conjunction with my Rachio Generator 2 controller. There is a limits section for amount of rainfall detected, e.g. 1/16”, 1/8” etc. I am assuming once this amount of rainfall is detected, watering is shut off. How long does this rainfall detect condition last: 1 hr, 12 hr, 24 hr, 48 hr. I cannot find this anywhere.
I live the Phoenix metropolitan area. Let’s say I have rainfall detected at 1/16”. If I get 1/16" rain on day 1, I don’t want to irrigate then next day even if that day is scheduled. The desert plants already have enough water. If fact, I might not want to irrigate for several days after the rain event.
Is there any way adjust how long the rain detected condition lasts?
Kind of a loaded question. Depends on what schedule types you are running. If fixed schedules, the irrigation will run on the next scheduled time like @franz said. If you are on Flex Daily, that will depend on the moisture level, based on zone settings. But even though desert plants are drought tolerant, 1/16" isn’t enough rainfall to sustain them. That is BARELY enough water to dampen the top 1/2" of soil and will not provide enough water to the root structure.
