The implementation of the Solinteg Inverter Modbus Protocol is based on Register Table version 00.03 (2023-06-26) - see file in repository.
Most Thing, Item and Sitemap definitions are automatically generated based on a NodeJS script and an Excel file as the basis.
Some definitions are added (automatically) from manually maintained files.
The resulting files are stored in the folder structure below openhab, so in most cases copying the various files to the corresponding folders of your openHAB installation should do the trick.
It's also necessary to install the Modbus binding (https://www.openhab.org/addons/bindings/modbus/). You can do so by adding modbus to the
services/addons.cfg file in the line binding = .
In order to run the script you need to install NodeJS as well as the relevant depdencies:
npm install exceljs
