Energy dashboard showing high values after update 5.0 and 5.1

[Anonymouse0104]

The problem

Since the core update 5.0 (and yesterday 5.1) my energy dashboard values are ruined. It has been working for years but for somehow it reads the values wrong. The biggest misread is the PV side, but the grid side is wrong also if I check the sensor changes in de integration (DSMR).

The dashboard:

The input sensors:

Hey there @mletenay, @starkillerog, mind taking a look at this issue as it has been labeled with an integration (goodwe) you are listed as a code owner for? Thanks!

Edit: seems to be aa GoodWE integration fault? The sensor Total PV Generation sets a 0 value every 5 minutes?

Same issue started 2nd of may

[mletenay]

Which inverter model ? And please provide some logs around these 0 values.

[fnurkje]

Model: GW5K-DT GoodWe Firmware: 909.909.09 / None

Just turned on debug logging, let you know results tomorrow

[mletenay]

Hmmm, it seems I might accidentally break the DT inverter code in this commit https://github.com/marcelblijleven/goodwe/commit/f41674ce0a784f77cdbea6a8858765327f18f3c0 Before that, when inverter failed to response properly (weird on its own), the value decoded to None and now it is 0.

I can confirm the same issue. I also have a GW5K-DT on firmware 10.10.0b

Fix for the above mentioned problem is on the way, but what bothers me a bit is it looks exactly like this ticket https://github.com/home-assistant/core/issues/115837 , but that was reported on 2024.4.1 where there was previous version of the goodwe library ...

Same problem here since 2 may, Goodwe GW8K-DT

Same Inverter and software, I will wait untill the fix

Sorry for the troubles caused, but it seems there is a bug/problem with DT inverters that they sometimes report 0xFFFF/-1 as value of the total power/energy registers. And recent fix in underlying library which addressed problems with power values on large inverters changed decoding behavior, which was (unintentionally) working around this (not known) DT problem.

To be honest, I have no idea how to fix your energy dashboard data. If my assumptions are correct, the 0 values should be removed and the rest recalculated ? Not sure how to do it or if it is possible at all ...

This fix is already implemented and is waiting for review. If you cannot or do not want to wait for next HA release, the fix is already present in v0.9.9.18 of HACS version of this integration - https://github.com/mletenay/home-assistant-goodwe-inverter

There are 2 ways to fix the dashboard. Restore the backup you hopefully made before the upgrade from 2024.4.

Another way would be via the development tools, statistics. Then find the correct statistics entry. And there you can adjust incorrect entries. But this is a manual job. It does have a tool to show outliers to find them easy, but you still need to manually calculate the correct value.

Thanks for the quick support and actions!

For anyone reading this ticket. The calculated sum value of the statistics starts massively increasing after a 0 value is reported. In order to fix this you can install the sqlite addon select the records for your goodwe entities metadata_id and export them. Fix them in excel and delete the records in HA and import them again + a restart. Unfortunately I found the developer tools statistics to be lacking when it came to correcting the values of the goodwe entities to a correct value. Maybe a good improvement would be to become more strict with the reset when total increasing is selected. Since the reset values aren't being changed while HA treats the 0 being reported as a reset.
