Also similar - our Tesla Solar stopped producing (again). 3 week wait for service tech. In the meantime I had Claude probe the inverter, find endpoints for retrieving status, re-setting AFCI and Modbus TCP (for HA monitoring), etc. Claude was able to obtain installer mode access through a review the javascript bundle. I had Claude turn all this into an iOS app, which I used to gather data to diagnose the issue over the next week. Had Claude summarize the findings into a PDF that I provided to the Tesla Solar service rep, which in the words of said rep was very helpful.
