PowerCalc

Home Assistant component that estimates power consumption without smart plugs.

Pluginfree

PowerCalc is a Home Assistant integration that estimates the power and energy use of devices such as lights, fans, and media players that cannot measure it themselves, without requiring a smart plug. It creates virtual power, cost, and utility-meter sensors, and can combine devices, rooms, or a whole home into one energy total. It is intended for Home Assistant users who want energy visibility across their home.
