The only devices I'd want a sensor for would be a TV and a front projector, both of which seem like they'd be best suited to a current sensor. The VCR that doesn't have a discrete "power on" code, I leave turned on all the time -- the power draw difference, as Dell says, isn't too significant.

So, to recap all the above, it sounds like I won't be able to easily get the T2 and its accessories to only send the power-toggle code to my projector if it's turned off. Bummer.
