Instead of doing it all in RM, I am doing most of the work in the new RL app (formerly was doing it in the ML app). I have two identical setups, except the Master Bath has a slightly more complex RM to fade the light in at certain times. I honestly could do this all in RL if I setup my modes better, its on the to-do list.
Using this to control the fan based on humidity: [APP] Smarter Humidity Fan *FORK for Testing*
Here is my RL app:
Light comes on at 10% (RM adjusts it further)
Light can turn on via switch or Motion.
If the light is already on, do not activate (in case switch was turned on and level adjusted BEFORE motion is triggered).
For turning off, Motion inactive for 8 minutes, OR when the fan turns off, + 2 minutes delay (shown at bottom).
Do not turn off if Fan is on (someone in shower), or motion active (someone in bathroom).
This combo allows the motion to turn off, unless the fan is on, if the motion goes inactive and the fan is still on, and the fan later turns off, then the light will turn off in 2 minutes.
Here is the RM to adjust the level
