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

...

Configuration details

Konfiguration (/etc/evcc.yaml):

# open evcc at http://evcc.local:7070
network:
  schema: http
  host: evcc.local # .local suffix announces the hostname on MDNS
  port: 7070

# mqtt message broker
mqtt:
  broker: 172.27.1.10:1884
  topic: evcc # root topic for publishing, set empty to disable publishing
  # clientid: foo

# unique installation id

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.
