Any Insteon Thermostats that can control a TWO STAGE AC?

I just purchased a Venstar 1700 thermostat and (belatedly) read the specs and found that it can only control a single stage air conditioning unit. My new high efficiency AC has two stages. (The wires are R,W,B,G,Y) Are there any Insteon compatible thermostats for this type of AC?

Certainly. Both the T1800 and T1900 support 2-stage A/Cs (and 3-stage heat). The T1800 also comes in an INSTEON integrated version (here).

I can vouch for the quality of service with MacHomeStore, having purchased almost all of my INSTEON hardware from them.

Following up on this a little - as I may soon be replacing my existing HVAC system with two-stage heating and cooling, it was good to figure out that my existing Venstar (the T1800 with integrated Insteon) can control two-stage units.

The question: Does it report anything about using Stage 1 and Stage 2 separately? I do a bunch of monitoring of my home status, such as when and how often the heating runs, and knowing how often Stage 2 was being used would be helpful (especially while I'm trying to tune up the Stage 2 configuration).

Bummer. Time to start looking into I/O options for sensing the W2/Y2 calls directly, I guess.
