Saw this today.

Obviously a bug somewhere, but where? EM115, Inverter, GivTCP, ...?

I've got most of the skills/tools to help track this sort of thing down, but any clues as to where to start would be useful.

I think I saw something about this in the GivTCP change log.

Is there an update waiting to apply for that addon?

TX200 No, all running the latest: 2.3.3

I'm not sure where this reading originates. It should start at zero at midnight and only monotonically increase through the day.

I get the occasional weird reading, you can just edit them out in dev tools>statistics, give that a try and see if the rest of the graph corrects afterwards. Takes a few minutes after editing for it show any changes

Interesting - didn't know you could do that!

Obviously something wrong, though. TCP/IP won't randomly change the data, so either the Inverter's sending bad data, or it's a bug in GivTCP.

I think it is where the daily reset effectively occurs at the wrong time of the day so you get all the current days data in one lump again.

For example you have consumed 5kwh from midnight to 5pm. This reset then occurs (in HA) so counts all the daily energy at that point in that time slot. Then goes back to normal.
