And finally here are the pump specs attached.
So from amazon I’ll grab this: http://www.amazon.com/Orbit-57095-Sprinkler-Weather-Resistant-Outdoor-Mounted/dp/B000VYGMF2/
and this pump start relay you mentioned should work: http://www.amazon.com/Orbit-57009-Sprinkler-System-Horsepower/dp/B000I19I5E/ref=sr_1_1?ie=UTF8&qid=1425237870
I’m still lost on how this would wire up to the OSPi esp controlling the zones. Any guidance appreciated.
