LCD Energy Savings (backlight off)

[chris1howell]

Add basic energy savings.

Add ability to turn of LCD back light after x minutes of inactivity with the RAPI command $FB 0.

back light will turn back on automatically with any state change.

If you're in there tinkering with storing energy cost anyway, it would be really great to report accumulated cost for the current period, total cost for last period, and day of the month the period starts.

TOU electrical rates that everyone in California is on make this slightly more complicated, which is why I haven't tackled this myself.

While I doubt the energy savings will be much - probably not more than a few cents a month. The bigger issue is a brightly lit screen drawing attention to an outdoor installation at night.

I agree the LED off while not actively charging would be nice to reduce light pollution and drawing attention to the installation.
