#Derive Three-Phase Motor State

Hi all, I would like to derive the state of a three-phase motor from the power curves of the individual phases at the main meter. When the motor is turned on, the consumption on all three phases increases by approximately 850W simultaneously. Can this be achieved using a template sensor?

probably, but you'll have to provide more details about the math you want to perform

I think the math is not that complicated. I need to calculate the difference of current and previous state of three different sensors. If the delta of all three at the same time is between -850 and -870 the template should return on if between +850 .. +870 then off

Maybe "same time" must be specified better ... Let's say within 2 second
