It’s in the first post and in the instructions on the repository:
For VSN300, the base address should be 0. Regarding the slave id, you should be able to check on the inverter if it has an LCD display. I don’t know if the slave id/unit id is also available on the VSN300 webserver. Did you check there also?
If you can confirm these values are correct, then the problem might be that the response to the statusvendor is not one of these below, and I need to add it, but I need to see the value first. Did you do a fw upgrade? If so, what is the date of the fw, if available?
Download qModMaster, so you can check if you can communicate with the inverter through the VSN300, then when it’s working, we’ll read some values: QModMaster - Browse Files at SourceForge.net
