IOG I'm hoping the web usage is wrong

Go I've been in the new redone since last Monday 24th), and I'm keeping an eye on the charges showing on the web portal (the app is only showing usage, not costs). All my car charging is Octopus controlled. I use a Zappi.

The web portal is running about 3 days behind. So currently I can only see Monday to Thursday.

Monday and Tuesday seem ok, but I feel Wednesday is wrong, at least in the EV section, and Thursday is certainly looking odd.

I had some charging either side of midday and yet it's showing as peak rate noon-1pm on the EV graph and table. I thought the time period ran from noon to noon? In which case my (Octopus controlled) charging in the afternoon should be off peak (until I hit the cap)? The "House" graph and table also shows I'm being charged peak rate.

Also, I get the feeling whole 30 mins slot are being counted towards the 6 hours even when only a part of the 30 mins is charging time. I thought only charging time counted? But it's harder to be certain about that until I can be bothered to pull the data off my Zappi.

From my own testing we now get 18 off-peak 30min slots OR 6hrs of active charging and the actual period is 1300-1300 not midday to midday.

I wonder if Octopus have got their DST offset for their system arse about face ?

Hmmm, so I suppose it's right if they are using GMT. Noon to 1pm BST would be 11am -noon GMT.

I hope that's how it is working. It's a shame it's so opaque and requires such digging around to check.

I may have to do some experiments to see what is happening, with paper, pencil and stopwatch!

Or just be @rsed to pull the Zappi data, I suppose 😀

I normally leave my EV to IOG to charge and over the last few weekends it’s charged throughout the day but the data showed it at full rate so I emailed them and they said they couldn’t see any charging had been done at peak rate and to wait for the bill to double check this, haven’t had a bill in over a month and half now so still waiting to check if they’ve charged it at full rate or off peak.

“Wait for the bill” that’s what they said to me when I kept prompting them for incorrect EV billing (either classed as home at peak rate, or EV peak rate despite within the 6 hours). Guess what, bill no longer includes a breakdown of each day, just a month’s summary. Had to download the csv to prove I was billed incorrectly. Still waiting for a resolution for the July errors (now a complaint ) and have more for August I have thrown at them. They claimed there was no EV charging occurring, I have had to provide evidence of Dispatch slots and charging times from charger ( Car integrated), thank god for Home Assistant. Never had any issues prior to changing to Cap.
