New Smart Meter: TOU1 (Time Of Use) clocking consumption but not using TOU2

Hi All. 
We had our first ever smart meter fitted some weeks ago now which had to be replaced by an emergency engineer a day later as our storage heaters and hot water would not come on. (Economy 7)

The new meter seems to be communicating with OVO to some degree but is only using TOU1 and is not using TOU2 at all which displays 00000 kWh. We have agreed a peak/off peak plan with OVO but the IHD is displaying a single tariff of 30.86p per kWh which is not our agreed plan. Any advice would be greatly appreciated.

If you think your smart meter requires an ECAUL and ALCS configuration please contact the Support Team.
 

Ok, that works for me. It would appear that ECAUL hasn’t been set up in that case. I’d recommend getting Support to check for and apply both ECAUL and ALCS configs to fix this.

There’s also ways to fix the bills so that your usage gets rebalanced and charged correctly.

It probably just needs the ECAUL settings and a tariff update applied. OVO Support can do that if you let them know.

    Thanks Blastoise for the info. I’ll give them a try. It’s not been a very good experience so far with changing to a smart meter. Thanks again for your help.

    Hi Blastoise. 
    Will OVO eventually get around to resetting the ECAUL and tariff settings automatically without my intervention do you think? 
    Thanks again.

    If it doesn’t get done within say… A week or two… Stop by the forum again. There might be other options that can be explored.

    But please try to resolve it with OVO Support yourself first.

      @Simonlee feel free to post some photos of the meter, including one showing the underneath with the cables going into the meter. We can at least check that you have a 5 port smart meter with the 5th port in use. If you do, it should rule out a physical set up issue, and we can turn our attention to how the smart meter is set up on OVO’s systems. You can refer to this forum thread with our web chat team if need be so it’s handy to have pictures and advice here if and when contact to our Support team happens. 

       

      It’s worth getting this sorted without delay, we should be making sure the meter’s off peak register is clocking your usage when it should be.

        Yup! That’s a five terminal meter! I need to see the meter display next. :)

        It appears to be an Aclara SGM1300 Series or Aclara SGM1400 Series. The most likely one is probably Aclara SGM1412-B or Aclara SGM1416-B.

            Thanks again for the help. I’ve spoken to OVO just now and they have assured me that someone from the meter team will be phoning me back. 🤞🏻🤞🏻
