Hey Ray,
can you clarify what you mean by the 5v terminal port:
“2) OpenSprinkler has a +5V terminal port, it can be used to power the controller. Find a 5V mini UPS and connect it between 5V and GND and that will keep it running.”
Is that an internal connection on the AC version or the external VIN terminal which I understood was for 5v output?
After this discussion, I realized this option for redundancy is so easy and cheap, that I may implement it even if I may never need it.
