EDIT: I'm unable to reproduce my own issue by only unplugging and reconnecting the ethernet cable from the PI. There must be another issue in my LAN.

I noticed that it freezes the last reported value from Fronius SmartMeter after being interrupted from LAN, while other services continue reporting on reconnection (e.g. Fronius Inverter).

Reboot always fixes it.

Hi,
I'm having trouble connecting to the meter.
Here is the error msg:

The host ip, is the Fronius Inverter IP?

config.ini
[DEFAULT]
AccessType = OnPremise
SignOfLifeLog = 1

[ONPREMISE]
Host=192.168.1.105
MeterID = 1
intervalMs = 800

#Role = acload

Thanks for the help
