2017 North point mystery switch question.

[Redneck51]

Hi Everyone:
Inside my 17 North Point 2 ft. straight in front of the entry door on the right wall. Right next to my touch screen I have a big black rocker switch. I assumed it was the main lighting switch because I can only turn them on/off either behind the control panel door or down low beside the door (both inconvenient).
I always thought the big black wall switch was the 3rd leg of a 3 way and it just didn't work.
But upon taking it apart and ohming the rocker it appears to be working.
Question: What does this switch operate? Manual says nothing. And nothing seems to function with it.
Thanks for your time.

do you have a ceiling fan...house type big rocker switches are usually for a fan.

Turn it on and pull the chain on the fan to turn it on there also.

I was confused about a similar switch in my bathroom. It was a second switch for the fan.
