I wondered if anyone knew how much battery power the Juice Plotter application actually used as it is monitoring the battery? I'm reminded of a rather embarassing situation when I recently acquired an energy monitor for my house. I went round switching everything off, and couldn't understand why electricity was still being used. A few hours later, I realised that the energy monitor itself was using the power to do the monitoring. I just wondered if I would be better off getting rid of it altogether? Any thoughts would be appreciated.
