I would try working with the delay, rather than defeating it. There should be a simple way to send the appliance module an 'off' command 5 or 10 minutes after the system (or a particular unit) is shut down.

Maybe a simple 'if..., delay, then...' macro of some sort. Of course, an 'on' command must be sent for power up.
