Introduction
We’re very pleased to introduce your npower home energy monitor, a handy little gadget to
help you keep an eye on how much electricity you use and what it costs.
It’s part of our smartpower range, the name we’re giving to our programme to help all our customers
get the most out of the transition to smart metering over the coming years.
Your npower home energy monitor can:
• allowyoutoseealmostinstantlytheeffectofturninganapplianceorlightonandoff
• giveyouarealtimeguidetoyourelectricityconsumptioncosts
• helpyoucompareyourusagefromonedaytothenext
How does it work?
Your npower home energy monitor has a sensor which is fitted around the output cable connecting your
meter to your fuse box or consumer unit. The sensor measures the amount of electrical current passing
through the cable and the transmitter sends this information wirelessly to your display unit in near real time,
providing you with an indication of your energy consumption.
You can install and set up your npower home energy monitor yourself - just read this booklet carefully before
you start.
Please note the npower home energy monitor only acts as a guide. It does not communicate directly with
your meter and cannot be used to provide meter readings to your supplier.

Installing your npower home energy monitor
Locate your meter
First you need to locate your electricity meter. You
can normally find it on an outside wall, in the garage,
basement or utility room, or in an outside meter cabinet.
Modern office blocks, apartments and flats may have
meters in communal areas with safety panels to protect
the wires entering the meter. In this situation it is
recommended that you contact a qualified electrician who
may charge for the service.
Single tariff meter (not Economy 7)
If you have a single tariff meter you should find four cables
exiting the meter. Ensure there is enough accessible cable
coming from the bottom of your electricity meter. The
feed cable (Cable 4) is the live cable exiting from the meter
to the fuse box or main switch. Clip the sensor to Cable 4
(Cable 4 will always be on the right hand end of the meter,
see Diagram 1).
Some installations will have Cable 1 and Cable 2 covered,
or partially covered to prevent any tampering with the
supply (see Diagram 2). Clip the sensor to Cable 4 (far
right cable).

8
Dual Tariff Meter (e.g. Economy 7)
Dual tariff meters (Diagram 3) will often have
an auxiliary cable running between Cable 3
and Cable 4. Auxiliary cables will be smaller in
diameter than the feed cables, and will run into
an adjoining metering device. You should find
five cables exiting the meter. The feed cable
(Cable 4) is the live cable exiting from the meter
to the fuse box or main switch. Connect the
sensor to Cable 4 (Cable 4 will always be on
the right hand end of the meter, see Diagram 3).
The transmitter comes with an adhesive Velcro
pad which you can use to fix the transmitter
casing to the wall next to the meter. UNDER
NO CIRCUMSTANCES should you drill fixing
holes or hammer nails into the wall in the
vicinity of the meter, the cables or any other
electrical equipment.

Frequently asked questions
Q If I remove the batteries will I lose the information?
A The display unit has an internal memory, so information stored on the display will not be lost if you
need to change or remove the batteries.
Q How do I reset the display (clear the data and start again)?
A When it is in the ‘Energy Now’ screen, push and hold the button’s History and Mode for two seconds
until CLR appears on the screen. This will turn the display to its original setup (from factory) and should
not affect neither time or date. Attention! You will lose all the information stored in the memory of
the display.
Q Why does the display show a different reading to my electricity bill?
A The npower home energy monitor is a good indicator of your approximate electricity consumption,
but it’s only intended as a guide. The sensor doesn’t communicate with your meter directly and won’t
send your readings to your supplier. If your supplier asks for a reading or if you’re checking your bills,
always look at the readings on your meter (NOT your npower home energy monitor).
Q Where do I find my tariff information?
A You can find tariff information on your electricity bill or statement.
Q My tariff has a standing charge. How should I calculate my tariff?
A Don’t include your standing charge in the calculation of the tariff. Your bill will include a unit rate
shown in pence per kWh. Just remember when you’re looking at your energy costs that you’ll also be
paying the standing charge each day, no matter how much electricity you use.
Q I have a tariff with two different unit rates, a higher rate for the first units I use and a lower rate
for the rest. How do I calculate my average electricity unit rate to enter a tariff?
A Take the total price paid for your first units of electricity, plus the total price paid for the rest of your
units, and divide by the total units. For example, 200 units at £0.20 and 50 units at £0.10 would work
out as follows:
(200 x £0.20) + (50 x £0.10) = (£40 + £5) or £45 for 250 units = £0.18 per unit
Q What shall I do if my monitor stops working?
A Check transmission symbol, check batteries in both transmitter and monitor. If still not working call
technical support 0845 0609950† or visit npower.com/smartpower. See page 3 for details.
Q I have three dashes (- - -) showing on the display. What does this mean?
A Move the display closer to the transmitter and press the link button. If the dashes remain on the display this
would indicate the transmitter and receiver are not communicating. Please contact our customer service
number on page 3 to help locate the problem.
Q Backlight appears to work sometimes, and not other times. Is my display broken?
A No. The backlight is on a timer to save battery life. The backlight is activated at darker periods of the day
(from 6pm to 6am), when any of the buttons are pressed.
