Hi,
Working with Grok, I have developed an application that interrogates the Emporia database via PyEmVue Python script and custom written C application. The C application also interrogates SBFspot output files for solar power data. The C application takes the Emporia data, the SBFspot data, and formats the data for sending to PVOutput. This supports both my Emporia VUE 3 hardware and my very old SMA Sunny Boy 4000US inverter. This application runs on a Raspberry PI 4 or 5.
If there is any interest, I will post the application(s) here with some basic installation instructions.
