After changing hardware and devices values end up all in the same day

[DJathome]

Forgive me for still being in the 'newbie' state.

After changing a few things in my setup (trying to a a second SMA inverter) the production daily values of the original one ended up all accumulated in one day as if al production was done in that date.
Result is that I see between 20 and 30 MEGAWatthours of production on, in my case, passed 4th of October.

Now to be honest I have some recollection of a similar problem being reasonably simply corrected somewhere here but it seems I am using the wrong keywords to search as after some hours browsing I did not find a post on the subject yet.

As you might see in the attached screenshot all my production from the past years months and days end up on that 4th October.

Attachment are currently not working on the forum.
But you probably can delete that huge spike from the graph and database by clicking on the value with shift button pressed. A popup will be shown to confirm the deletion of that incorrect value.

Ok thanks for a swift reply, does this also restore the values to their dates in the past?

[waltervl]

No, but probably the values are there but you do not see them due to the huge difference. But better check with a csv/excel export that you can do from the graph (check the hamburger menu in the graph)

The "issue" you had is something common, happening when a cumulative counter goes back to zero (is reset) externally. Is probably occurred when you installed your second SMA inverter.
Using "shift click" method, you'll only loose the 4 October production. If you have a way to known/estimate it, it's possible to "force" it in database (at your own risks).
