Standards relevant to the development and supply of smart meters.

keylevel

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".

  • The IHD is only a toy to keep the customer amused.  It plays no part in the billing process.  If it ever goes wrong, then many electricity suppliers will deny any responsibility after the initial 12 month warranty.

    Yeah, that's what I was thinking.

    However, it also appears as if the metering side is not correct, as my account with the supplier shows that there are no electricity readings as of the 17th September, even though the gas (which is relayed through the electricity meter) is working just fine.

    It has been nothing but a pain since it was installed - this is at least the third time I have had to report that it is not working and submit my own readings. At least the manual readings should be correct...
