Efergy E2 IR Energy Monitor - £20 at Clas Ohlson Manchester

The e2 wireless electricity monitor shows the amount of energy that a household is consuming at the time the display is read. The display can also give the user a reading showing usage in financial terms. You can walk around the home with your monitor device, switching appliances on and off, to see the difference that each one makes. With a few small changes in your consumption behaviour the e2 can help you reduce your energy costs.

Bought one of these in a bit of a beat up box from Clas Ohlson in Manchester the other day and find it really useful. Not sure if this is available in other Clas Ohlson stores, but definitely not available online.

The 'IR' bit refers to the optical reader. In the instructions it says it must be fitted to an IR LED (invisible to the naked eye). I don't have one on my meter but I do have a red blinking LED. I emailed Efergy and they confirmed it can be fitted to a red LED. I've found it works very well. Seems accurate too.

A great price IMO to be able to monitor your energy usage in real time if you don't want to pay for a more expensive one (such as the Geo) or a 'free' one through your energy supplier (which often turns out not to be truly free).

As I mentioned in my original post a 'free' smart meter isn't necessarily free!

There's PLENTY of articles in the news about this.
Had an own electrical "smart" meter before having the power supplier fit a gas and electricity one. Being prudent like many on here can't see the point of these except for the companies, as we end up paying for them and they are saving on meter readers.
And if you do not have an understanding of the energy use of the appliances you have one of these smart meters will not make you smart?
Do smart meters show you instant usage, or do they only update once per day?

They have a delay of up to a minute, depending on the type.
The one in this deal for example is about a 30 second delay. I've connected this to the engage hub so I can monitor away from home and the delay is even less surprisingly.
