I have a 16 zone Rachio controller that controls my irrigation system. My system includes a master valve that the controller automatically turns on whenever any zone is activated, so that the main water supply piping in my system will be pressurized with water.
I am into smart home stuff, and also into computer automation through things like the Arduino microprocessor. I am considering tapping into my irrigation main water supply piping to some other things with the water. To do this, I would need to turn on the master water valve.
Turning on the master water valve is simple; all I need to do is to provide 24 volts AC to the master valve. But of course this is what the Rachio controller does, so I recognize that might cause some electrical interference problems that could damage the Rachio controller.
After doing some research, I see that there is an isolator available that is recommended for use when you need to have 2 or more controllers activating the same master valve. I believe that my situation is the same thing (me providing 24 volts AC to turn on the master valve), so therefore I need to use 2 isolators; one for the Rachio controller, and one for my home grown 24 volts AC application.
Do you agree?
Thanks in advance!
