ralfogit / libspeedwire Goto Github PK

In an effort to make sense of the SMA Sunny Home Manager 2.0's data stream towards the SMA EV Charger (and trying to convince it to modulate its output accordingly) I did some data logging and spelunking in https://github.com/danieltwagner/speedwire-parse

Now that that's complete I realize that it's largely overlapping with what you already determined for the energy meter, though there are some additional messages and I haven't determined any addressing, as seems to be referenced in your repo. I do see a sender ID (maybe susy id?) and serial number but nothing to determine the recipient... unless I'm missing something.

Anyhow, long story short, would you accept a PR that adds some relevant constants? I haven't yet looked closely at what would be required but figure it can't be too bad based on what I'm seeing here

Hi there,
i adapted once your libspeedwire for integration with SBFspot.
Just our of curiosity:
how do all these protocols relate together?
Is speedwire used by both: energy meter AND inverter?
Is production data of an inverter also multicasted (like the energy meter does)?

Thanks a lot already! :)
