sorry I didn’t want to clutter the page here if it was not your problem. That error is because the response is providing two responses, 1 for inverter and 1 for battery.
I modified a lot of the flow, and made it user friendly. Feel free to import to your NodeRed, and follow the instructions. You need to modify 2 nodes only, and then click “Create Sensors”.
