Actual Historical Meter Readings
Hi
I am in dispute with our supplier. We have just been through a heatwave and they claim we used 8X our normal winter gas usage in one month. £960. This is based on meter readings. However their gas usage shows a more realistic £50 usage in 30 minute increments.
I was hoping to use Bright App to download actual meter readings in 30 minute increments to see how and when the meter reading jumped so significantly in a short space of time. I am looking at the download data and it just shows usage, which matches the suppliers usage, but what I need are the meter readings.
Hope this makes sense?
Can anyone help?

Hi,
I have access to our meter readings, but only via MQTT from a Glow CAD.
Unfortunately I don't believe that Hildebrand can access meter readings from the DCC as their access is classed as 'Other user' and doesn't permit this - I had an email exchange with Jane about this a while ago.
The usage data that your supplier gets from the same source as the data that the Bright app is showing - it comes from your smart meter via the DCC, so I am not surprised that it matches.
I'm struggling to understand why there is such a discrepancy between the periodic usage figures (assuming that you have all of them for the whole month) and the cost calculated using the meter readings. The periodic usage figures are calculated on the fly from the measured volume for the period using a default calorific value and the rate stored in the meter; the monthly cost is calculated separately by the supplier billing system from the start and end meter readings (which are in m3), using an 'actual' calorific value and the 'actual' kWh rate. There will always be a difference between the total of the periodic figures and the monthly calculation because of the way they are each calculated - and I don't believe that the periodic figures include the daily standing charge. But the discrepancy that you are seeing seems excessive.
If you can't resolve this I think that you will have to ask for the calibration of your meter to be checked; at the end of the day all suppliers bill on meter readings.
Hope this helps a little.
@stuartb - if the Bright & supplier ½ hourly readings match (as they're both sourced from the meter via the DCC) I think the onus should be on the supplier themselves to do the maths and to compare their meter reading totals with their calculated ½ hourly usage
