The Custom Rule facility can be used to adjust 'raw' power values.
This can be used to remove solar generation at night.
e.g. if(power > 0 && hour < 4) power = 0;
The above resets power to zero when it's value is greater than 0 before 4:00 AM
Use the 'Test Rule' link to test your rule before saving the configuration.
