@Avia1 - The Rachio can REPLACE the Hunter control unit - it doesn’t work with. If the wiring was finished it would be easy to instruct which wire from the Hunter goes to which port on the Rachio. From the picture, there are two cut wires left on the Hunter, a potential missing common wire (see where the white wire in the wire nut is connected) and the wires that are hand held. If it is known where those wires go, no problem. It might be better for the sprinkler guys to finish and then swap or see if the sprinkler guys can install a Rachio instead of the Hunter.
