Glad to hear that a less destructive or non customer involved method may exist to solve the problem.
I came from the home automation realm. Saw the DT36x branded as Crestron back in 2000 or so. The Crestron hardware that these talked to is fairly proprietary. My interest peaked on the box that the Pentair system uses as a pool has motor, valves, heater, sensors and, well I can only imagine what else. If the "box" that pentair uses has dry contacts 110v input and some basic sensor input my first thought was to use it in a home setting. If its of a design where it takes in 220 power, transforms it to different voltages I may not be as interested. Good stuff none the less.
Are you on CE or Win XPe?
