SolaX - Sudden spike in reported energy data

[jirihelmich]

The problem

Sudden spike in reported energy data, pretty much 100x the real usage. E.g. produced 200 kWh electricity on a relatively cloudy day during 1 hour on a PV with produce capacity of 9.45 kWp. The battery has 17 kWh capacity, yet HA says it stored 190 kWh of energy. The consumption of the house is off the charts as well. Unsure what's going on. Attaching screenshot from energy dashboard SolaX cloud, and relevant data exports. Did not touch anything neither before or after - broke itself, "fixed" itself. The most unfortunate part for me is, that I have no way of fixing the data manually (as far as I know), hence my data is now broken forever, and all daily, monthly, weekly and yearly stats will be affected by this - or is there a way to edit the snapshot somewhere?

The most unfortunate part for me is, that I have no way of fixing the data manually (as far as I know), hence my data is now broken forever

Go to Developer tools -> Statistics, filter on the entity and click the icon on the right (slope with an arrow), this allows you to alter you data.

It is unclear to me if you configured the solax integration today, or if it has been running fine for some period of time.

I'm just going to submit this now while I look more into it since it has already been more than 10 minutes since I started writing it.

Thanks, I will have a look. I have this integration running for approx. 4 months. Jirka

This explains where the number is coming from. Had a similar issue with a group helper sum of energy consumption before: #135404

It looks like you are using a custom Solax Modbus integration, and the issue seems to be in pyModbus 3.8.3, see this issue comment

[jirihelmich]

I don't think I use that integration, not sure how you came to that conclusion?

[KIvosak]

Apologies for the confusion. I'm experiencing the same issue with custom integration, which I mentioned earlier (in HA 2025.2.0). After upgrading to 2025.2.1, it stopped working completely.

Yesterday, I rolled back to 2025.1.4, and so far, everything is working fine.
