I do not see a way in Indigo to make this switch, though. Is there any kind of workaround that you guys are aware of, or am I stuck with the old thermostat until I pay $500 or so for the installation of that control board?
Basically, I can set a variable to pull the outside temperature, and if I can find a way to tell the thermostat to manually change to aux heat when that variable drops below a certain temperature I would be set, and I could forego having to add equipment. Any help would be greatly appreciated!

I could have one power input come to the relay, and run one wire to W1 and one wire to W2 on the thermostat. Using Indigo, I could say something like "if outside temperature is less than 45 degrees energize W2, and if outside temperature is greater than 45 degrees energize W1" (obviously completely different syntax, since I'd be telling it to use relay output one or two or something similar, but you get the idea). Does that pretty much explain the concept?

FYI - I emailed Venstar on March 28th '11 and their rep said they will be coming out with a ColorTouch T5900 which will be compatible with Insteon through the same plug-in jack (INSTEON Thermostat Adapter Model #2441V) used on the T1700, T1800, T1900 series. I can't wait!
(The ColorTouch T5800 is NOT Insteon compatible.)
