Standards relevant to the development and supply of smart meters.

What standards apply to the development of smart meters? If there are any, are there different ones for the backend (data collection) systems, metering and in-home displays?

I am asking as I am concerned with the quality of the software in the one I have in my house. Specifically:

  1. It sometimes "forgets" that I have a gas meter - the IHD will, for an unspecified period, only show electricity-related parameters and settings.
  2. The kWh reading for electricity sometimes "goes backwards" when it updates the display. The reading is updated every 10 seconds, but the display will sometimes show something like 12.3 ... 12.2 ... 12.4 when it updates (all numbers shown over a period of less than a second).
  3. I often have the IHD set to display kWh used rather than cost, as I find kWh more useful. However, the display has now stopped updating the electricity used value (i.e., it is frozen), and will only update if I switch to cost and then back to kWh.

I am hoping that the quality of the software within the metering and backend is better (and, ideally, subject to regulation), and that the IHD is being treated as non-critical "consumer kit".

  • My IHD sometimes behaves oddly too - once reporting that may usage for that day had topped several tens of thousands of pounds! I did check and the corresponding error wasn't reflected on either the meter proper or the subsequent bill. I just put it down to a lack of (or insufficiently robust) error detection/correction for data passing over the wireless link between the meter and IHD. Usually turning the IHD off and on again restores normal operation.

    My smart meter also dropped off the radar with my supplier for a time - as far as I could gather it was some problem with their own back office system rather than anything to do with the meter itself or its communication with the rest of the world. Leastways it seemed to be corrected by customer services sending an e-mail to another department, rather than anything having to be fixed at my end.

  • I am steadfastly refusing to have a smart meter fitted. I am fed up of the endless guff from EON stating that I must have one by law or safety. I pay a 'service charge', so I demand the service I am being billed for, namely, the delivery of my bill by post, and the reading of my meter manually. If they don't wish to do this, they should drop the level of the 'service charge' to reflect the reduced level of 'service' being delivered.

  • I suspect they will be more likely it increase the service charge for those who don't comply!

    Resistance is futile... You will be assimilated...
