Why has my new dual smart meter stopped recording night rate after power outage?

Hello, we’ve recently (late Feb) had a dual tariff polyphase smart meter installed in response the RTS shutdown.  We have two phases as we have underfloor heating, so it has been a long protracted affair in getting our old legacy meters replaced with an Economy 7 polyphase compatible smart meter.

 

This was done back in February, credit where credit’s due, the three phase trained OVO engineer was brilliant. The meter signals the off peak period to our underfloor heating controller, this has worked correctly since the switch.

 

Just to be on the safe side, we took daily readings from our old meters just before the switch and daily afterwards so have a good idea on our daily consumption and to check for constancy old/new.

 

We have the Kaifa MA329B

 

We’ve been away for a few days and returned home last night and realised our new smart meter has stopped recording usage on the T2 tariff register. Virtually all usage since we were away is on T1 only. This points to something being amiss.

 

Points to note/events since we were away:

 

1. We had a planned power cut of 9 hours notified in advance by our DNO.

2. We had a second unplanned outage of c2 hours two days later

3. The IHD had a new message “Elec meter initialised” when we turned it on

4. We have new charge rates since 1 Apr (like others on a variable rate tariff). The IHD correctly reports the new E7 day tariff.

5. We did not get the 1 hour new tariff countdown on the IHD from 2300 last night. After 2400 the meter was still registering T1, it should have switched to T2.

6. Our underfloor heating failed to trigger on.

7. Our OVO account still correctly lists us being on Economy 7.

 

This seems to point to a faulty meter or config as a result of the power outages perhaps??

 

Additionally our smart meter has only sent one pair of readings since installation, on 21 March which was the end of our last billing period, our account is listed as every 30 min for readings and settlement. This doesn’t sound right either.

 

Any advice, knowledge or input would be really appreciated.

 

Many thanks!

Good news!  The remote reset does appear to have done the trick.  We got the tariff change countdown last night 1 hour ahead of the off peak cycle and the overnight usage was registered against the T2 tariff.

 

As ​@Nukecad . suggested, the cycle remains on UTC so started just after 0100 BST, with the countdown 1 hour earlier.

 

Our underfloor heating was also correctly triggered during the off peak cycle, thankfully.

 

Also, we’re now seeing the daily 1/2 hour usage in the OVO app too, which is a real bonus.

 

Hopefully we won’t see the same happen when we next have a power outage.

 

Thanks everyone for your help on this.

Hey ​@power_user 

 

Sorry to hear this.

 

We don’t have access to accounts here at the Forum and it sounds like the Support Team could do with checking the meter data.

 

Please do get in touch with them so they can take a look for you, it sound like the power cut has caused some kind of issue but sadly we can’t be sure of what without the same information the Support Team have access to.

 

Let us know how you get on here, it may be helpful to others in the community to know how you get on.

Ok many thanks for the advice ​@Abby_OVO and ​@Emmanuelle_OVO 

 

I’ve spoken to the support team, they confirmed the meter was set to only send readings monthly, this has been reset to 1/2 hourly and have performed a reset on the meter. This should hopefully fix the off peak cycle within the next 24 hours.

 

Told to check back again after this. Fingers crossed.

 

Will let you know how we get on.

I’m not sure if this will apply to you but something to watch for is that if your meter was switching to T2 at 24:00 it may (or may not) now be switching at 01:00 instead.

That because last weekend the clocks went forward to BST  - but not all dual rate meters adjust for that change.
They still change from T1 to T2 at 24:00 UTC - which is 01:00 BST.

So if your E7 T2 was 12:00 to 07:00 UTC in winter you may now find that it’s 01:00 to 08:00 BST.

(BST) Summertiiime, and the weather's still freezing.

Thank you ​@Nukecad .  Yes we were aware that the BST switch may push it an hour later so we waited up until 0100 (ish) just to be certain. As we hadn’t been at home since the clock switch we weren’t absolutely certain what the summer hours were.

Hopefully we’ll see the countdown from 2400 tonight.

thank you
