Two not particularly related questions:
- I recently had my old smart meter exchanged for a new SMETS2 model. The main fuse was removed before this happened, of course. However, I had had an eye-wateringly expensive electric shower just before the engineer arrived and got to work. Checking my half-hourly usage data afterwards, I saw that the data for the half hour immediately preceding the power cut as well as up to the moment he reconnected it were missing. I take it that the usage data for that half hour just didn’t make it to DCC, so I won’t be billed for it. But OVO are sure to be billed for it by the DNO - so do OVO just absorb the cost? Or can I expect an adjustment at some stage?
- My meter is set up for E7, although currently the peak and offpeak rates are the same. I have been comparing daily meter readings with what I would expect them to be based on the half-hourly usage data, nicely recorded to the nearest whole Wh. Four weeks on, these are the results:

I was pleasantly surprised to see that the totals are the same, at least within any reasonable tolerance. The over-reporting of the peak usage, however, isn’t unremarkable. OK, it’s neither here nor there as regards the consumer’s bottom line, but I wondered if anyone could suggest where it might arise from. My own guess is the difference between the time of reporting Hh usage around midnight and the time the meter readings are submitted. In my case, the daily difference amounts to about 4 minutes consumption, so that could be linked to the random offset of the switching time between peak and offpeak.
Any ideas?
