Gene,
I’m very happy to tell you that the added white common wires did the trick! I needed to connect the two ‘unnecessary’ white wires coming from the isolators together in order to get everything running perfectly. Now the only issue is that I have a zone that goes up and will not come back down… assume it is the solenoid and will replace if necessary. Thanks to you, I am not giving up on Rachio! way to save the day…!!
Best,
Jeff
