I don’t have direct contact with the previous owners, but I can ask my real estate agent to see if he can reach out. Only been a home owner for 2 years. Can wrench the hell out of a car, but this irrigation thing is the hardest thing ever.
Thanks for the help. I’m gonna try the multimeter test. So the wires don’t have to be connected to the Rachio, right? Example, I put it in Continuity mode, black on white wire, red on other colored wires. I should be seeing 20-60 ohms?
