I just got an IQ20-RS and it's great being able to use my phone to operate the system. With my old RS4, I had no way of controlling the air supply for the spa jets other than running back to the pool house and removing/placing a cap on the intake pipe. I wonder if I could get a cheap Jandy valve and an actuator and somehow hook it up to the RS aux line to control the air line with my phone too? I do have the J12 (electric heater) jack free as well as aux4-7 available.
