    I am looking to upgrade my ancient sprinkler controller with a new wi-fi enabled one. I do not need tons of fancy features since we are pretty limited on when can we use sprinklers due to the water restrictions. Currently, I can only water on Wednesdays and Sundays.

    My question is, does the RainBird ST8 controller offers an automatic skip of watering day if there is a rain in the forecast or it had rained a day before? I.e. if the system is set to go off on Wednesday, can the ST8 stop Wednesday's watering if it had rained on Tuesday or rain is expected on Thursday? That's pretty much the only feature I really need in the new controller as it will save me from constantly going to the garage to manually turn the system on and off.

    The only rain controllers I'm aware of shuts down watering only after it has already rained. A forecast on a 50% chance of rain won't cause your controller to stop from running, since heck, even the professional weathermen are only about 10% accurate. Oops, I guess being politically correct, "Weatherpeople!"

    I agree that 50% chance of rain means that we may not see a drop of water but if I could set the controller to skip watering when i.e.75-90% of rain is predicted, that would be good enough for me. I can then use my phone to turn the system on in case it doesn't actually rain.

    I am also reading about the B-hyve controller and it has a rain delay feature that can be set for +/-24 hours so I am assuming that if the rain is in the forecast within 24 hours (before or after the scheduled watering), the controller will skip the program for that day.

    Yeah, even my $29 Orbit controller has a rain sensor and a potential rain delay which will postpone 24, 48 or 72 hours.
