I found some instructions online. There's a little bit of fiddling with hardware to do, low voltage wiring mostly. Basically it involves putting something between the datalogger and inverter which you can use to access the inverter directly. Then you can use plug ins to Home Assistant to monitor and control your inverter without interrupting the normal data flow. I used this method with two Waveshare RS485/Modbus to Ethernet adaptors. There is another method with a dual RS-485/Modbus to wifi module somewhere.Whoosh that went over my old head, I assume that something to do with connecting to the data lines outputting from the solis inverter. Getting the data from there would be so much better than 3rd hand after its been to the cloud & back. Have you documented this somewhere for others to follow?
I don't use HA, but have a Pi that grabs the data for me and displays a simple text mode status display like this
