Energenie Ener007 Energy Saving Power Meter Monitor and Reduce Appliance Energy Usage - Energenie

I was on the fence about buying this item due to old reviews stating it was a pretty poor product. On arrival I simply read the manual and got to using the item straight away.Good:+Watts from our appliances seem to be very accurate with a +-deviation of one watt which is nothing to fuss about (When compared against two other power meters that arrived).+Fairly simple to set up in my opinion. Easy to reset measurements and for those with dual systems, you can input two prices.+Unlike what I read beforehand, resetting appliance usage does not clear your price per kWh. Probably an issue with older models perhaps?+Timer function is handy. The amount of time the appliance has been used only goes up when there is an active current. So if you have an appliance that stops and starts, the usage time with only show for time when it was actually using electricity.+Price. For a tenner, one really can't complain.Bad:-Display is pretty naff. Viewing the display from angles is quite difficult. You typically need to be viewing the display in a straight line.Overall I can't fault this item really. A tenner gets you a device which is very handy in seeing what's actually using up your current. Now I can tell my parents to stop worrying about my 30w fan ;)

I had to buy this as a replacement for a very old Energenie power meter that had gone out of calibration and couldn’t be repaired. The new one offers some improvements in available information and seems a bit more stable than the old one ever was. Some of the symbols are not very clear so it is necessary to consult the instructions to work out which readings are being shown.

I was a little unsure when purchasing this as a few reviewers had mentioned that if you wanted to measure different appliances the only way to reset the accumulative power, cost and time was to actually press in the reset button which would also loose the electricity tariff values and then need to be entered again.I don't know if the unit has been improved since those reviews but on my unit as clearly mentioned in the instructions you can reset all of the values individually by pressing a combination of two buttons – this will then reset either the total time, total power or total cost and the tariff values will not be lost.I have checked the energenie on various appliances and also light bulbs of know wattage and it seems pretty much spot on it it's readings.The screen is clear and easy to read but if it is in a dark area you may struggle to read the values so a torch would be useful.Also worth mentioning is that the unit has a battery backup so if the unit is unplugged it won't lose the data, this has a battery saving feature in that when you unplug the unit the display will show for about 30 seconds and then go off but all you need to do is press any button to turn it off again.When it is unplugged from the mains you can read all of the collected data which is stored in the memory but can't of course read live data.The only slight criticism is that when setting the tariff it will only allow you to enter the value to the nearest pence – for example my tariff is 13.3455 pence per kw/h but the nearest that the unit will allow you to enter is £0.13 which isn't a major issue but could add up over a long time.Overall though an excellent unit that I would recommend.

I purchased this recently because I wanted to look at the consumption of a 2kw heater in my new insulated workshop. This seemed to fit the bill. I set it up and priced a kWh to the nearest penny. The batteries were already installed and the LCD was clear and bright.I attached the heater with an extension lead, as advised by other reviewers-which is a good idea. I proposed to keep this monitoring the radiator indefinitely through the winter. I set the thermostat at around 10c, the idea to just have a background heating. (this is within it's operating temp range)This morning I went to the workshop, and found the unit had functioned very well, and was showing that my heater (modern oil-less radiator) was running very economically. I left it on and returned in approx' an hours time, and was dismayed to find the display had dimmed badly to almost invisible. I tried a reset which did not correct the display. I decided to remove and clean the batteries.The screws as mentioned in reviews, are indeed very tight and your average Phillips screwdriver will only burr and not remove them. I have a good selection and found the ideal tool.I cleaned the batteries and reinserted them but no joy. The batteries are only supposed to hold the readings when you remove the unit from the power source, and I presume the LCD powers up independently from them. I note on the Energenie web site they have a newer model at £2 more. I have not given up on this unit, there is no slur on AMAZON they are exemplary, I have already arranged for the unit to be collected tomorrow, without cost to myself and had an instant refund.I have ordered another unit and hope for better luck, most reviewers are pleased with the unit, maybe I was just unlucky, you have to expect the odd dud now and again. If I had ordered from the main supplier, I would have had the inconvenience of posting it back at my expense - so congratulations to Amazons' excellent logistics. If I get a good one I shall be very pleased indeed.I hope to leave another review for this product - hopefully 5 stars *
