@Mr.Sparkle
I know you haven’t posted here but I need your Expert advise.
Looking at doing something down the read with HPA and are looking at getting an Arduino. I am also looking at a Raspberry pi 3.
I know that most use the Arduino but being that I am a long way away from setting anything up, the PI is more usable now.
What are your thoughts on using PI with Android or Linux to run relays and pumps?
