SofarSolar Values incorrect, but correct values via Modbus proxy

[Studhey]

Describe the bug

Hello,

I have since today a strange behaivour. I´m using the modbus Proxy to connect ioBroker modbus adapter to read some values. These values do all look fine. But in evcc all (SOC and amps look ok) values seems to be random (see log) The values from the wallbox seem ok.

I deleted the MQTT values and I first thought it might be that the configuration was not fully applied to use Modbus, I change to that yesterday.
However I restarted evcc, deleted the container and also "evcc migrate --reset".

Steps to reproduce

...

What type of operating system or environment does evcc run on?

Docker container

External automation

• I have made sure that no external automation like HomeAssistant or Node-RED is active or accessing any of the mentioned devices when this issue occurs.

Nightly build

• I have verified that the issue is reproducible with the latest nightly build

Version

0.133.0

I have tested it deactivating the modbus proxy, but no sucess.

I changed my configuration to take all values from ioBroker, even ioBroker gets them through the evcc modbus proxy, it does work for now.
