Internet friends, do any of you have a Fronius Gen24 series solar inverter on the same network as a Linux computer? If so, could I trouble you to please run the following two commands and send me back the output? avahi-browse -rv _Fronius-SE-Inverter._tcp avahi-browse -rv _Fronius-SE-SmartMeter._tcp (If you've not got the "Smart Meter" addon then the second command might not do anything, not to worry if so.) Is all in the aid of reverse engineering for interoperability. If what I'm trying to do works then it'll be open sourced. 💪 Boosts for reach appreciated!

@projectgus@aus.social does it help if it's a Fronius Primo inverter, or you only need for Gen24 ?

@projectgus@aus.social I have a Gen24 and just installed avahi on a Linux VM. I don’t see anything back from either of those commands and there’s nothing vaguely Fronius looking in “avahi-browse -a” either?

@projectgus@aus.social I've got a Gen24, but not a Linux computer at the moment, just macOS. Let me know if I can still help somehow.

@projectgus@aus.social are you trying direct access over tcp instead of going through tcp + modbus ?
