E-Max Home Energy Monitor Kit

E-Max is the latest energy monitor from Efergy. Now is easier to keep an eye on your energy use at home than ever with a big 7.9? display, faster performance, battery for room-to-room portability and USB-2.0 port to download your energy consumption data. The E-Max uses intelligent graphics – like a speedometer to show current energy use and a budget bar to help you keep track of costs.

The E-Max will show you when you are on your peak tariff, alerting you to avoid using high energy-consuming appliances, such as washing machines or tumble dryers at this time. You can even set High Usage alert to let you know when you may just have too many things turned on.

You can also easily download your energy data into a CSV formatted file, and use Excel on your computer to read the data stored. The data downloaded include the latest 31 days, 12 months (hourly), and 24 months.
