Hi,
You mean you want to use a microcontroller to measure the current and voltage and calculate the power? You can measure samples of the instantaneous current and voltage and do the math, or you can measure just the time delay and assume a partial sine wave and do the math for that instead (a triac partial sine wave is very predictable). Either way you end up with the average power which you can compare to anything you want.
