The full story
A Renac N3-HV-8.0 hybrid inverter's WiFi dongle accepted TCP connections but never answered Modbus requests. After a lot of time with ChatGPT, Claude and searching, the poster says Claude "did the trick": reading the inverter through Renac's undocumented cloud API with Home Assistant REST sensors.
The credentials come from the browser's network tab after logging into Renac's site. The known catch is that the access token has to be renewed from time to time.
