Fire alarm that saves light state

#1

So real quick, I’m making a piston where when a fire alarm goes off it turns on all my lights, set what lights it can to a given color, and it will blast an alarm through my Google Home speakers.

I’m having a problem finding a way for the system to save the current state of the lights so it can be reverted after the alarm goes off. Does anyone know how to do this?

It might help us to know what brand of lights you are using.

NM I found the answer.

It was a mix of hue lights and I think some others. Plus some that plug into a smart plug
