Hi Evan,
Actually I am wondering the same thing. I just wired in a RainBird in place of my OSPi as we are renting the place and it will be more familiar to contractors. I did a dual-box installation where I am interested in leaving a RasPi in place for flow monitoring and wondering if I can just use OSPi vs. a custom solution.
Curious if anyone’s done any mods or observation in this area?
FWIW from my prior experience when the zones are running you can see deviations from prior usage.
Thanks,
David
