Fronius Virtual Smart Meter App

Hey community.

I had the following challenge: Next to my Fronius inverter (Symo Gen24) and a Smart Meter TS 65A-3, I also have two smaller Growatt inverters in my installation. While they report data into Home Assistant via OpenInverterGateway (MQTT), the data was not visible in my Fronius environment.
Although Home Assistant has this visibility, I wanted to combine it natively in Fronius, e.g. to have a holistic view of the real "PV Surplus" to charge an electric car.

My addon solves this: GitHub - M4rt1nCh/ha-fronius-virtual-smart-meter: Home Assistant App that simulates a Fronius Smart Meter that is exposed via Modbus TCP · GitHub

It is basically data of 1..n inverters from home assistant entities and expose them via Modbus TCP as a "Fronius Virtual Smart Meter" to the Fronius environment. For me, this integration works like a charm and ensures a holistic view within the Fronius ecosystem.

This is the first app I've created, so I'm welcoming feedback and suggestions. On top of that, I wanted to share this as I think this could be useful to others :slight_smile:

Add-ons no longer exist and building new Apps and using the words and links to the old way in the readme is very confusing for users wanting to try your stuff...

For instance, this don't work:

  1. In Home Assistant go to Settings → Add-ons → Add-on Store.

It would be good to proofread what you repost from other sources to make sure things are right. I hope the code itself doesn't have the same kind of problems.
