OK guys..
Here is the first draft of the 'Super Smart Fan' 
If configured correctly it should:
- Turn on the fan when it's too humid (turning off when humidity returns to a normal level - based on a baseline sensor)
- Turn on with motion. - Turn off automatically after a pre set time period when motion stops (if humidity is normal)
- Turn off automatically after a pre set time period when manually switched on (if humidity is normal)
You can find the app here:
Have a thrash about and see if this works ok.
I've tested fairly well but using only virtual devices, as always... bug reports and suggestions always welcome
