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!
