-You can use a "Riemann sum integral" (called integration) to convert it.

-Restart Home Assistant for the sensors.yaml to be loaded.
-Make sure SunGather is running, wait 5 minutes for initial data to populate.
-Navigate to the Energy platform (Configuration > Energy). Add these sensors to the following areas:
