Modbus Error and ReadHoldingRegistersResponse != ReadInputRegistersResponse after upgrade to 1.8.0 #56

Closed capsel22 closed 1 year ago

capsel22 commented 1 year ago

Hi,

I'm seeing a lot of errors in Home Assistant Core log in System -> Logs. I haven't seen these errors before. Not sure what to include, apologies. Happy to supply anything given instructions.

I'm using GIV-AC3.0 inverter

As per the "Limitations" section on the README these errors are from the givenergy_modbus library rather than directly from the integration. This is likely to improve with some improvements being made, however a new version is not yet available.

Unfortunately the upgrade to 1.8.0 is almost certainly unrelated. It's more likely to be something to do with system or network load as the modbus connection seems very sensitive to these.
