Hello everyone,
I am new to node red and have a simple question.This probably sounds like a broken record for most of y’all. I’m attempting to build an aeroponics veggie garden and need some of y’alls expert help. I’m using a raspberry pi 3b with a NCD relay controller and need to to control some solenoid valves. I have already gone through some of the basic tutorials and have used the inject and delay nodes off the pallet (pretty dang cool thanks node red). Now to my first of many questions... what would best way to have this valve open for 30 sec then close for 5 min and repeat indefinitely. Thanks In advance for your replies and advice.
