Fan turns on when it shouldn't!

#1

Hi,
I have a piston that turns my bathroom fan on, only when the light switch is PHYSICALLY turned on, however, the fan goes on even if another piston turns it on.

Line 24 says if the switch is physically turned on…

I have another piston that turns on this bathroom light. How can I stop the fan from kicking on if another piston turns the light on?

WebCoRE is capable of distinguishing physical versus programatic turn ons, but it only works if your Device Handler reports that info. Unfortunately, 98% of device Handlers do not.

Maybe you can build off of this brilliant idea.

Oh, I see!

Thank you.
