Ok, reopening this conversation about replacing a Hunter iCore 2wire system which I loathe beyond words.
Understand I can’t reuse the Hunter wiring, so I need to run new wire to every valve. The valves are in a few clusters around the property. I would rather not retrench from every set of valves a home run to a central controller.
I could do a minimum of trenching by using several controllers around the property. BUT, there is a Master Valve.
In an ideal world, Rachio software would be able to treat several controllers as a single logical controller, with one of the controllers wired to the Master Valve and that one controller turning on the Master Valve any time any zone is running on any of the controllers. Do I live in that world?
