IHD showing under usage

Hi ​@Tricko ,

Your IHD simply mimics whatever charge is shown on your meter so if that has been updated recently (our has) then that may be the cause. They should of course show the standing charge (which is usually added early each day) but I have seen units that don’t do that.

One other thing with your new supplier … do you have a split tariff at all ? If so, some suppliers (including Octopus) have begun to set your meter and therefore your IHD as well to a cost per kWh which is an average of your annual cost. Not useful for daily usage which is why I have purchased an alternative device from Hildebrand - their Glow IHD is very useful and can integrate with other systems to give very accurate cost readings

Hey ​@Tricko 

Welcome back to the Forum! I’m glad to see BPlightlog has already stopped by with some helpful advice on this. 

BPLightlog previously wrote the following helpful topic on third party data providers, I wonder if that might also be helpful here if you consider getting an alternative device:

Well yesterday we used 6 KWh and IHD said that was 90p. We cleared all settings on IHD and let it come back on only took 5 minutes decent strong signal I suppose. It is still reading very low but with accurate energy use. We had a search through and found a tariff of 12.6p on the IHD and THIS we think is the issue.
It has been reading this SEG payment tariff as our import cost since we signed up for outgoing octopus. We have checked the Smart meter and this also says Active tariff is 12.6 p not our 24+ p. Although our account shows what we are being charged each day. Heck knows how it’s happened.
going to be a long phone call 🙁

You might want to double check your bills as the 12.6p could be an average unit cost for your usage.

As I mentioned earlier, the IHD simply picks up the tariff from the meter and as you’ve already noticed, you will be charged at your actual tariff cost rather than what the meter suggests. 

Our Export rate is definitely the 12.6p and it seems too much of a coincidence for it to have only happened since we started the Outgoing tariff. But will check with Octopus to confirm.many thanks
