Hi there,
i made a json service to integrate my old pv inverters into venus os. It uses the solarlog500 Logger.
I also have a modbus version online, but with the json variant I can get the power readings of each pv inverter and then map them on the correct phases. The modbus version supports only a single power reading for all inverters together.

have fun.
