NEW PICTURE

http://www.electricity-monitor.com/images/owl_micro_which.jpg

sorry, I listed the older model picture by mistake
the one I got was the new one with the buttons on the back, not the front (as above)

Good price! I thought I'd done quite well when I bought one a while ago from Tesco instore at £14.99.

It really is quite sensitive to the varying current draw and helps focus your mind on just how much energy appliances are using.

Bear in mind that it is not wholey accurate and is mean't as a guide only - says so on their website. Still, it's a 'fun' product :)

Nice, but the wireless range is poor and it eats batteries like crazy.
#4
these are great, had ours for 8 months now and we've managed to halve our electricity bills after becoming a bit obsessive about switching off things at the plug when not in use :) great product. :) never had problem with batteries, not sure if that's just that we've been lucky or if its an inherent fault otherwise.
#5
as it is stating £20 id doubt ill find it for £10 in store round our way.

lol you needed a device to tell you to turn things off at the wall?

Not exactly - these devices show you exactly how much each is using - some are worth turning off, others not.

A bit of common sense goes a long way!

I got a device similar to this and it saves me nothing. I already knew that anything with a heating element inside burns energy and should be used as little as possible (e.g. if you're making 2 cups of tea only put enough water in the kettle for 2 cups!) and leaving things on when not in use is obviously wasting electricity :|

The good thing about these is they will show people exactly how much they might be using/wasting.

My experience is different. It never fails to receive from the opposite corner of the house, and 7dayshop Good To Go rechargeables in both transmitter and receiver have lasted six months.

The main annoyance with it is the limited resolution - you will see that the reading jumps up and down in large steps only. Don't be deceived by the apparent resolution of one watt.
#11
Showing £20 online and a different model. The one above is the older version so may still be available instore.
#12
We got one of these free with an electricity company (British Gas possibly). It actually had the opposite effect on our house - when we saw how little the PC/TV/Sky box was costing per day, we stopped turning them off as much :)
#13
Does this measure individual appliances or just the total household consumption?
#14
Only the whole household consumption. Even if it could measure an individual appliance, you would get a more accurate result from a plug-in meter.

As pibpob said, it measures the whole house. You clip the 'transmitter' onto one of the 4 main lines coming from your leccy box, and it reads the current using magic.
#16
S'not magic it's induction...

http://en.wikipedia.org/wiki/Electromagnetic_induction

The flow of the current produces a magnetic field - more flow = stronger field, which can be measured.

Physics lesson over

I've had one for a couple of years and the range is fine. I use rechargeable batteries, and they last about three months between charges.

This is a good product, but the more up to date model tells you useful stuff like how much lecky you've used in the past 24 hours.
#18
Don't forget you can get the owl wireless USB dongle that will link to the transmitter so your PC can record your usage on graphs and export excel data.. Can only find them on ebay, but they are great.

free from npower and also you get £90 cashback if you join their dual fuel
#20
Don't change supplier because of bribes - use the comparison sites and change if your bills will be cheaper, because that will dwarf any introductory payments.
#21
Had one for about a year, first change of batteries this month. Mine cost £30 from comet, so this is a good price.
#22
to answer a few questions

this is the new model not the old one, I've just updated the picture to the correct one, sorry :)
(I just cut-n-pasted someone else's thread tbh)

the link goes to Tesco because I got the wrong store when I posted it, then I rewrote the title, ooops
it does actually come from Asda

batteries - it comes with AAA's so I guess they don't expect it to use much power, although you can change the poll rate from 6 secs to 60 secs to reduce power usage if you like.
I'm going to rig mine to some rechargeable D cells so it should last a year

The radio range is fine, it goes through two brick walls and right to the end of the house, which is better than my Wi-Fi does,
its the same frequency that door bells use (433Mhz)


The display shows the current power or cost and then the overall total at the bottom,
they quote the accuracy as being 10%

I was surprised how much my computer and TV used and will think twice about boiling the kettle!

Picked one up from Perry Barr Asda yesterday, were two left on the shelf after I grabbed one! Clipped it on and worked fine, realised just how much juice the tumble dryer takes though! scary!
#24
I was looking to buy one of these...I have a prepayment key meter though ..If this tells you what the whole house is using then how do you work out each appliance like tumble dryer for instance ??
#25
Switch everything else off first. A tumble dryer eats huge amounts of energy, so if there's any way you can use a good old fashioned washing line, then I strongly recommend you do.
#26
I bought one in dagenham store today (plenty left for a tenner)... it's not all that compared to the one bought on maplin for £29
