We have recently switched from the Centameter to the Efergy meter as it represents a better buy. We use one to monitor our power consumption, it costs less than a Centameter and it logs your consumption by the day, week, month and year so you can log your improvements over time

 Besides providing you with instant information on electricity use the Efergy includes many other display settings to provide the user with the most up to date and in-depth information on energy use.  A summary of all the readings that the Efeergy can display:

• Real time power consumption (kW)
• Accumulative cost ($)
• Hourly rate if usage ($ / Hr)
• Hourly rate of CO2 emitted by use (kg / CO2)
• Time and Date
• Historical record – per day for 7 days, previous 4 weeks and monthly records recorded on a 64KB chip.
• All Historical readings shown in costs ($), kWh (consumption) and CO2 emissions.
