I wasn't even aware of that possibility. What a total X10 noob I am. Sounds like a real option.

Is there a corresponding X10 RF transmitter, so that I could use X10 control over all of it?

Maybe this is how other folks have used X10 with a UPS... Or am I really asking about something very unusual that noone really does?

Thank you for all your comments. More gold stars.
