Hi: I’m replumbing a house from the meter box and would like to be able to remotely turn on/off the house water and irrigation water. Both water lines are 2″, which complicates finding valves. It appears that Hunter ICV irrigation valves w/ a 9VDC DC latching solenoid would work, and not be super expensive. I don’t want to have my valves turned on or off w/ a program. I want to just manually turn them on or off and have them stay as I set them. Not having a opensprinkler controller to play with, my question is if it is possible to easily just turn on or turn off a latching solenoid valve from the web server? From a http request also?
A related question is whether it would be easy to have a pressure sensor connect to the controller and be able to read it on the web server also? I can convert the voltage/resistance to pressure by calibration. Anyone got a suggestion for an appropriate pressure sensor?
