I have the same problem as others; valves cycle on and off when wireless sensor is calling for postponement. In my case it’s a Rainbird. Ditto with the very low voltage at the sensor terminals. Unfortunately the Rainbird receiver has a fixed pigtail so using shielded wires isn’t a viable option. The pigtail is only about 12″ long, and it still induces noise. Hard to believe the sensing terminals on the timer are so sensitive! Sure would be nice if Orbit published the schematic for the timer (at least the front end of the sensing circuit) so we could ensure that the 0.1 uF capacitor filter is the right solution. Guess I have no choice but to give it a go. I’m not an big electronics guy (electricity yes, electronics no). Does it matter what type of capacitor is used? Is a ceramic disk type ok?
