first of all thanks for your job!
I’d like to use opensprinkler pi but i have this question: i can use PoE with a 24v splitter but problem is that POE use VDC not VAC.
And second things:
220Vac to 48Vdc (switch), then 24Vdc to opensprinkler pi, Vdc to Vac, Vac to Vdc to 5v 😮
sorry for my bad english but i hope you understand my worries
