Modbus Error: [Input/Output] Unable to decode request #168

Closed gyrex closed 3 months ago

gyrex commented 3 months ago

Hi,

First of all, fantastic project - thanks so much for taking the time to do this! I just helped a mate set up his Sungrow SG10RT to log data to pvoutput using Sungather but there's some strange errors being logged and I'm hoping someone might be able to tell me what these errors mean? Sungather seems to be working OK despite these errors although I did have to set the level: 3 parameter in order to get the total_active_power register to show up.

I'm running this on docker.

OK, I think I fixed it. It appears that the program was unable to successfully detect the inverter's model number (SG10RT) which is why I had to use level: 3.

In config.yaml I changed the following:

model: "SG10RT"

but with level: 3 I was still getting the error messages so I changed it back to level: 2 and now I can see the total_active_power register and I'm not getting the error messages.

I think this indicates that the level 3 error message generation is creating the index out of range errors? Actually, no - I occasionally see these errors on level 2, with the model fixed in the config.
