Hi, i have a bug, where i changed the entity names, because i used a different device for a month, but now i want to change it back, but i cannot do that, because the old data will be lost...what can i do to prevent that? Also the older data before i changed the device for a month also got lost somehow or not? What should i look for?

I'm still lost, because the old entity i used for 1 month i removed, it only shows up in the energy section, not in the developer tools.

#

It won't be a problem if the data is removed, but the old data from the original entity's must remain, because it's now the same entity again.

What version of HA are you running?

fluid agate Aug 25, 2023, 5:35 PM

#

Home Assistant 2023.8.4, Supervisor 2023.08.1, Operating System 10.5

#

Also the 4th option isn't working here: https://gist.github.com/langestefan/acbf7e42b15b302e9aacc08663039e57#4-my-energy-dashboard-shows-a-weird-spike-of-x-kwh-how-can-i-correct-it

#

I want to correct the data, because it registered the solar panels as consumers and produces negative kWh

We are still working on question 4 because it's a complex issue

#

You can try going to dev tools and statistics and adjust the sum there

#

I'm getting this rn, i included the old entities and the new ones (that i used for a month).

#

I used the old one today and i got negative values, but i can't find it in the statistics.

#

the new one was used for about 15:30, when i changed it back to the old one.

#

Now it's working, but i still want to remove yesterdays huge negative solar production value, how can i do that inside the developer tools?

#

Dev tools-> statistics, adjust sum

#

I cannot find that spike in the statistics it's all 0kWh

#

little crest Aug 26, 2023, 4:20 PM

#

you can add a positive value to compensate the negative one

#

Thanks for the tip! It worked, but i still don't know where did that spike came from. 😦

little crest Aug 26, 2023, 4:33 PM

#

Negative spikes are usually something to do with wrong reset timing

#

It's a bit complicated to explain

fluid agate Aug 26, 2023, 4:45 PM

#

Oh, ok so it's a HA internal software problem, not with the device that is measuring the energy.

little crest Aug 26, 2023, 4:47 PM

#

it's a mixture of both
