I have a large HWQS home I am programming (9 PNL-8, 40+ shades, 70 keypads)
The home has a exhaust fan recovery system. All bath exhaust fans are fed back to one location where a main exhaust fan puts the air back in circulation throughout the home. So, when turning on an exhaust fan in a bathroom I need to turn on the main exhaust fan. That's easy enough. When turning off a bath exhaust fan I must first check if any other exhaust fans are on and only turn the main exhaust fan off if no other exhaust fans are on.
I was hoping to share the logic via a scene/sequence but I don't think thats possible (or is it)?
Do I have to build a if then loop for every exhaust fan button?
