Efergy E2 Wireless Energy Saving Monitor

Product Review (submitted on 26 October 2009):

Works as advertised - dead simple installation. Will open your eyes to your power consumption. Especially like its data logging utility that enables you to download hourly consumption to you PC (CSV file format is a nice touch). Just a pity it does not do so at its native sampling rate of 6 seconds, for example to monitor your hot water heater thermostat activity. Would have liked ability to monitor and record more than one sensor input simultaneously but thats probably stretching it at the price.
