[BUG] warning in logs after update

[cmseasy]

Describe the bug
After update to 0.4.8. my log gives:

Logger: homeassistant.components.sensor.recorder
Bron: components/sensor/recorder.py:327
integratie: Sensor (documentatie, problemen)
Eerst voorgekomen: 11:25:11 (1 gebeurtenissen)
Laatst gelogd: 11:25:11

Entity sensor.envoy_122025007960_lifetime_energy_consumption_l3 from integration enphase_envoy has state class total_increasing, but its state is negative. Triggered by state -1259.672 with last_updated set to 2024-09-29T09:21:30.187820+00:00. Please create a bug report at https://github.com/vincentwolsink/home_assistant_enphase_envoy_installer/issues

Possibly caused by my gateway being in a sub-distributor. The CTs on the sub-distributer main switch also measure the feedback to the main distributor? And state_class is total_increase.

Possible solution: change state_class to total

Account type

Has that sensor value been negatieve for a long time or did it suddenly change?

[cmseasy]

It is negative after installing the CT's on sept. 13. On sept 18 I switched from HA integration Enphase Envoy (dev) to Enphase Envoy (installer)

Is I wrote the 3 phase metered gateway is mounted in a sub distributer. The L3 phase is not connected to anny device and only supplies to the main distributor. The other phases are used: L1: water pomp, L2: heat recovery unit.

The L3 descending metering is correct. I only supply back to the main distributor via phase L3.

Using a sub-divider is not unusual. Unfortunately, the consumption measurement is not the consumption of the grid but the consumption of the sub-distributor. I have no other option here. This is not a problem for monitoring grid consumption, I get this from the P1 meter.
Even YouTuber Ketel Klets has his gateway in a sub-distributor and mentions this in his video: https://www.youtube.com/watch?v=LnfeTiY7X_I starting from 5:45m. He mentions it as an advantage to switching off solar panels at negative prices.

That why I think the state_class "total" is better for these lifetime_energy_consumption sensors

I see. I also checked some Enphase documentation and this indeed seems the way to do it. For my understanding, could you maybe paste your output of https://ENVOY_IP/production.json?details=1?
