About Powercalc
Powercalc is a custom component for Home Assistant that estimates the power consumption of lights, fans, smart speakers and other devices without a built-in power meter, using virtual sensors. Light usage is calculated with different strategies based on brightness, hue/saturation and color temperature, while other devices use a generic calculation based on their relevant attributes.
On top of power and energy sensors, Powercalc also creates cost sensors to track spending, utility meters to break usage down by day, week or month, and group sensors to combine devices, rooms or your whole home into a single total.
