2 days ago Hi @andig , thank you for your fast response!
The first screenshot shows that the Battery SOC is 73% (which is correct), but the battery discharging is 0.0 w (which is not correct). In the second screenshot, it can be seen that the battery discharging 1.05 kW. In the EVCC logs can be seen that
[site ] DEBUG 2024/10/17 20:17:53 battery power: 0W
I assume that the EVCC sungrow-hybrid template can not properly calculate the charging/discharging power of the battery. Please let me know if additional info is needed.

2 days ago Hi @andig ,
I'm running the EVCC as a HomeAssistant Add-on and I can not run evcc meter command inside of the docker container (it can not find the evcc.yaml config file there).
But from the Log dashboard, I can see that the following value is not correct:
DEBUG 2024/10/18 14:50:21 battery power: 0W
At the moment battery power should be around 1000W.
I'm using EVCC as a Modbus proxy and an entire dashboard is based on the values provided by this proxy. On that dashboard I can see the battery power

I have installed the Evcc on standalone linux server just for debugging and was able to pull the evcc meter logs

1 day ago That doesn't tell me anything. Check the docs for Register 13000 Running State. Afaik our implementation is correct (based on https://forum.iobroker.net/topic/50564/bedeutung-codes-running-states-sungrow-wechselrichter). If new docs say differently we'd need them to double-check.
Closing until new documentation available.

10 hours ago @andig Thank you! Will check the docs and maybe some other open source materials. I see that evcc users have a similar issue: https://github.com/evcc-io/evcc/issues/15915
Describe the bug
Evcc cannot read home battery data while using "sungrow-hybrid" template. The inverter SH15T, communication device Winet-S2, and the Battery SBR128 are updated to the latest firmware.
The inverter is connected via the LAN port on the Winet-S2 dongle.
Still, the invertor data is shown on another dashboard and there the Battery data is shown:

Restart the Evcc
