Plug-in Electricity Consumption Monitor


Plug-in Electricity Consumption Monitor

Ever wondered how much electricity your TV uses on standby or how much you use each time you set a 60 degrees C wash going? If it plugs into a normal wall socket then this monitor will tell you how much electricity it uses.

Some items will use less than you think and you might decide to let those be, some will use more and you might decide to do something about them.

Be prepared for some surprises!

At HomeEnergySaving, we found our old fridge freezer was costing an amazing £158 per year to run (honest!), the new energy efficient replacement costs only £34 per year. Our Stereo, DVD player and kitchen TV on standby EACH consume as much as a 9w electricity saving bulb.

If you have heard advice to switch to energy saving bulbs, turn your TV off at the plug, do your washing at a lower temperature, unplug your mobile phone charger etc then this device will tell you exactly what savings you can make following this advice.

The perfect companion to this plug-in monitor is The Owl which will tell you how much electricity your whole house is consuming at any point in time.

This Power Monitor can perform many functions, all of which are described below:


Operating Modes

Mode 1 - Wattage Display
Display The power currently being consumed by the connected device is displayed. This value updates frequently as not all devices draw a steady current. Here is where you'll find out how energy efficient your appliances really are both when running and on standby.

In this example, 63.38 watts are currently being drawn.


Mode 2 - Cumulative KWh since reset
Display The 2nd most useful mode. This displays a running total of electricity consumed since the function was last reset.
Use this mode to measure the consumption over a period of time (e.g. 24 hours) of any appliance that doesn't draw a continual steady current like a fridge, freezer, washing machine etc.

In the example shown, the appliance has used 3.85 KWh of electricity since the value was reset.

Shown in the lower image is a display of the Maximum number of watts consumed at any time during this period. This maximum reading is available at the push of a button.

Mode 3 - Time since reset
Display For use with the above cumulative KWh mode. This displays the time that has elapsed since the last reset.
In the example shown, the appliance has been running for 23 Hours and 17 minutes.

Mode 4 - Voltage and Frequency
Display Typical UK values would be about 240V at about 50 Hz but the voltage often varies between 235V and 245V

Mode 5 - Amps Display
Display In this mode the current that is being drawn by the connected appliance is displayed. Also shown is the Power Factor, a definition of which can be found on the Wikipedia

In this example, 0.86 Amps are being drawn with a Power Factor of 1.0 CosPI.

Other Modes Include:
Display

Date/Time

Ability to set one or two prices per KWh with time bands

Readout of total cost of electricity consumed since the timer was reset

These functions are explained in the manual
