I currently use an X10 Appliance module (Smarthome #2021). There is also a Leviton wire-in version (Smarthome #2242I). Is your unit similar to either of these devices or is it more on the line of an EZIOx?
If it is like either the 2021 or 2242I, would the plug format be the same? If so, it would be perfect replacement for me, even though I only need a 20A device.
