I check my meter readings and usage figures on a daily basis. Since 6th April that data has not been updated online (browser) or through the app. Something is being accumulated and increased daily against the 6th instead of spreading over subsequent days as it should. Half hourly data is, of course, missing.
Here is a picture from my IHD for the 6th. Note that WAN and HAN are connected and daily data is displayed for every day on the IHD. So for the 6th my total energy usage is a plausible 29.30 kWh.

Now if we look at my online data it is a shambles. I have not changed plan/tariff since fixing last September, but something has gone very wrong. I assume it's just me as I've looked for other reports and found none, but online message chat-bot refuses to open and phones are closed so I'm stuck with posting here.

If someone could feed the hamster and get things moving again I'd be delighted.
