im pretty sure you nailed it 😀 ive been running things as they were for the past few days while i updated my plumbing and my electrical wiring. Making sure no shorts occur. im going to try everything tomorrow so i got my fingers crossed. this will make life so much easier. i even went out bought another raspberry pi and ordering another sprinkler pi because of how easy things have become and the ability to also implement temperature/humidity logging, HID lighting on/off etc etc.All i can say that this has been such a positive experience and has given me free time away from my greenhouse. thanks for a quick response and i will let you know tomorrow how things work out.
