Hi Snooz, Thank you for bringing up this topic :) I was thinking that these meters would be great if you could set a limit of how much power you wanted to use, and the meter would warn you, with a sound or flashing light, to let you know if you are exceeding your set limit, then you could go around and turn off a few lights or appliances, that weren't necessary, what are your thoughts on any other uses for these meters?
