Meter data unreliable after firmware update

[moedi21]

Describe the bug

Recently, my inverter (Home Hub 3 phase, SE8K-RWB48BFN4) has been upgraded to firmware 4.19.36. Since then, the readings of the imported/exported energy counter in the connected backup interface (SE-RGMTR-1D-240C-A) are missing for most part of the day. Also, the energy counters are partly downcounting.
After the update, I saw also a jump in the values, from about 290 kWh to 1311 kWh.

From the log, repeated frequently:
2023-11-27 06:57:54.380 WARNING (MainThread) [homeassistant.components.utility_meter.sensor] Total Import received an invalid new state from sensor.solaredgemodbus_m1_imported_kwh : unknown

Additional issue in the log:
2023-11-27 11:37:01.506 WARNING (MainThread) [homeassistant.components.sensor.recorder] Entity sensor.solaredgemodbus_m1_exported_kwh from integration solaredge_modbus_multi has state class total_increasing, but its state is not strictly increasing.

Expected behavior

Expected: Energy counters should be available without interruption, and also strictly upcounting

Read the Instructions

• I have read https://github.com/WillCodeForCats/solaredge-modbus-multi/wiki
• My configuration follows https://github.com/WillCodeForCats/solaredge-modbus-multi/wiki/Configuration
• This issue is not about a template error (template errors should not be reported as an issue, read https://github.com/WillCodeForCats/solaredge-modbus-multi/wiki/Template-Design-Notes)

Additional Context

I have tried in parallel to read the data with pure Python and the 'solaredge_modbus' package available in pip. There I get continous readings, but also partly downcounting:

{'import_energy_active': 1017522}
{'import_energy_active': 1017526}
{'import_energy_active': 1017531}
{'import_energy_active': 1017531}
{'import_energy_active': 1017531}
{'import_energy_active': 1017454}
{'import_energy_active': 1017457}
{'import_energy_active': 1017462}
{'import_energy_active': 1017462}
{'import_energy_active': 1017470}

{'import_energy_active': 1017473}

Contact solaredge support, it shouldn't go backwards.

[WillCodeForCats]

I'm closing this because it's not an integration bug: if the change that caused the problem was the inverter firmware being updated, then the bug is in the inverter firmware not the integration

Contact solaredge and ask them to downgrade your firmware to an older version that doesn't have this problem.

[moedi21]

Partly agree - the downcounting is probably caused by the firmware update. I have raised a ticket with SolarEdge support.
However, I also do not get continous readings from your integration, whereas I can get them using solaredge_modbus Python module. Not sure, why.

Anyways - thank you for your great work!

[WillCodeForCats]

The integration rejects values that are less than the reading before it because Home Assistant expects total increasing.

[WillCodeForCats]

I will add debug log entries for the error conditions as part of my sensor entity check refactoring that I'm already working on. You can see them anyway if you turn on debug logging, but I can also have it log why it failed a check.

[moedi21]

Thank you for the explanation, makes sense.

Just chiming in that this happened to me too last night. Though, according to the history, the issue started before the version was upgraded. My meter is the same inline meter in a home backup interface (SE-RGMTR-1D-240C-A)

Nonetheless, the values don't seem accurate at all anymore. I have a P1 device hooked directly to my meter so it's easy to compare and it almost looks like Solaredge has messed up and are displaying some completely different register values in the meter offsets relating to Wh values. The instant power register values are correct.

@moedi21 if you are able, can you give an update if/when you get some response? I'm going to approach our representative if this issue can be seen in the mobile app as well.

We already have an outstanding issue open about the inline meter reporting two times the power and energy readings compared to reality. This issue, however, magically fixed itself.

[WillCodeForCats]

Reopening for visibility.

[WillCodeForCats]

The integration rejects values that are less than the reading before it because Home Assistant expects total increasing.

PR #482 will add logging for this condition.

I have the same issue on a SE10K-RWS48BEN4 inverter after the upgrade to

All meter data for imported and exported kWh are not correct. Also the data shown on the Meter (SE-RGMTR-1D-240C-A) is not correct. It is approx 25% less than what is accumulated on the officia grid meter from the energy company.

However the integral of the imported Power results in the correct Energy.

In this picture you see, that at the time the version changed the meter data got unreliable and reseted to 0

Chiming in with an "unnafected" datapoint for those talking with SE - upgraded inverter to 4.19.36 a few days ago and my import and export are continuous lines in HA.
