I have a series 2 controller; it’s been installed about 2 years.
I have had an intermittent problem with the controller going offline. The device periodically trips the GFCI breaker in the enclosure and the unit loses power. There does not seem to be any rhyme or reason to it; it happens throughout the year and in hot and cool weather. Note that I live in So Cal so it can get very hot. That said it does not necessarily trip at 110 degrees, but may at 70.
Recently Rachio sent me a replacement power supply. It went 10 days without issue, but it tripped again this morning.
I’m looking for troubleshooting ideas. Is it the controller, the GFCI, weather?
