I am trying to figure out the wiring for from my old ESP Modular to my Rachio 3. Can someone explain the match-up for the wiring?
@copaaz - The three white wires on the COM terminal go into one or separate C terminals on the Rachio. The zone 1 to 9 wires from the ESP go to the same terminal numbers on the Rachio.
The orange and green wires from the bottom photo are not needed in the Rachio (the power adapter takes their place).
