Hi,
Just had smart meters and new style IHD installed and have a couple of questions please as have no user instructions.
1. By 6.00am every morning (when I get up) it tells me that I've already used around £1.30 of dual fuel on a total spend per day of around £3.50. Why so high when the central heating/water turns on around 5.30am?
2. What do the green/orange/red lights tell me at the bottom of the IHD, (not the meters)?
Thanks.
Jez
What do the green/orange/red lights on my Chameleon IHD In Home Display (IHD) mean?

Sounds like you’ve got the Chameleon IHD3, the smart meter In-Home Display we previously offered as the accompanying smart meter device:

The colored lights at the bottom of this display indicate whether your current energy use is low (green) medium (amber) or high (red). You can also click on the lightning bolt 'now' button to see your usage in real time.
As you mentioned seeing higher than expected daily usage costs, it’s worth factoring in your daily standing charges which are added to the ‘so far today’ figure at midnight. Also bear in mind some appliances (like fridge/freezers and TVs on standby) use electricity overnight.
For further information on how to use your IHD see the usage guide for your meter/IHD type below:
