hi @grinly no worries : )
I agree, I think MMM-JsonTable doesn’t like the structure of the json message you’re getting back - it’s expecting to see information laid out in an array and isn’t set up to parse a different message structure.
Your investigations into Node-RED sound interesting - it’s not something I’ve tried but just from a quick look you might well be able to get it to act as an intermediary between your inverter and MagicMirror. If you’ve managed to get Node-RED to call the inverter endpoint for the energy data then that’s a good start. You’re right, if you go this route I think you’ll still have to clean up/reformat the message for consumption by MMM-JsonTable. But the Node-RED documentation might help - it does look like there are ways to get data back to the module too - you could perhaps get MMM-JsonTable to call a Node-RED endpoint instead of the inverter directly, and Node-RED could serve “cleaned-up” json back to MM?

Another option might be to see if there’s an alternative MagicMirror module that can handle (or be configured to handle) a wider range of json (or XML) messages? Though you might have to get hands-on with a module to adjust it exactly the way you wanted. If your json message always follows the same format it shouldn’t be too hard to extract the values you’re interested in - I think there are some fairly straightforward modules that would give you an outline of how to request and parse json (e.g. MMM-stocks maybe?). If you wanted the output shown in a table you could take a look inside MMM-JsonTable and see how it’s done there too. Just scrolling the 3rd-party modules list there’s also MMM-Tabulator? I’ve not used this one either but it mentions displaying data from XML or json sources, so it might be worth a try.
