I live in an apartment where the shower can take quite a while for hot water to flow through the shower head and the temperature to stabilize. I already have my coffee maker & towel warmer on an X10 home automation system. I am searching for a plumbing attachment that attaches the end of a shower head that has an electrically actuated valve (low voltage DC) to allow water to flow so I can interface it to my home automation system via a DC adapter. This will allow my shower to automatically start in the morning. To those who are lacking electricity knowledge, I am not at all talking about using dangerous voltages near water. So please dont misunder my post. Thanks
