New user here. I also read all the threads related to this particular topic, but my wiring is a bit different as well as my desires.
I apologize for the messy wiring which I tried to clean up for the pic (included a clean schematic pic). My Hunter Pro C has a rain sensor, remote, and solar sync attached.
I do NOT want any of these when installing Rachio.
From reading the other threads, I assume that I would then just need to cap off ALL the wires going to the top left corner (SEN, REM, AC1, AC2, GND).
The only wires I would then need to connect to the Rachio would be C and 1-11 along the right side. No M wire.
Did I say all that correctly?
