 An integration sensor is quite useful in energy billing scenarios since energy is generally billed in kWh and many sensors provide power in W (Watts).
 
-If you have a sensor that provides you with power readings in Watts (uses W as `unit_of_measurement`), then you can use the `integration` sensor to track how much energy is being spent. Take the next manual YAML configuration as an example:
