To Bruce's point...the extra math and variable storage requirements are why the community app was created for humidity sensors and bathroom fans. This app has been absolutely solid and I'm sure if you drop a request, the dev would be able to add a contact sensor to disable the humidity check.
Although I did not read this whole thread to see what @hpgurgel is trying to exactly, consider it requested. There is already a "Disable smart mode with switch", I am sure I could either add contact sensors to the same menu, or add a second menu for a contact sensor.
I am getting pressured to release my app officially so I guess I need to get on it. Seems like I am done with my drivers for time being so I should have some time.
