Hi Benjamin, I’m afraid I don’t think this is going to work directly as none of the push formats suits the input formats of emoncms.
(the English version starts at page 31 for anyone else looking at the pdf)
you can see examples of the emoncms input formats used here Emoncms - site api
is there any way to query, request, pull or poll data from the inverter? Then yopu could use nodered or a custom script to read the inverter, parse the data and post it t emoncms that way. Or I guess you could still use the push service to push a text file via FTP and the read that, parse and post to emoncms I guess.
Have you searched this forum for “Fronius” ? I’m pretty sure some users have indeed interfaced with some Fronius inverters and posted about it. eg Monitor Fronius Primo 5
