Thanks for the feedback on the safety issue. Would I be correct in assuming there isn't a significant sound issue?

While I could implement a solution similar to what you have suggested, this will cause some issues for the wife and kids.

Consequently, I am still interested in finding a solution that I could automate. For example, is an X10 type solution an option.

I understand the Panamax 5100 and 4300 type units would work but they are in the $130 - $200 plus range. I would love to find something cheaper. However, if anyone has a comment about the 4300 I am interested in their experiences.
