🚿 Bathroom Humidity Exhaust Fan

[Blacky]

Hi Matthew, glad you like it

@mattdm

I don’t think the falling derivative is really the right trigger for turning the fan off.

I have been using this automation for some time now and has never missed a beat.

@mattdm

It would also be nice to have a direct humidity-limit trigger — if it’s over 80%

You could do this but I have found that if the humidity is over 80% it is just natural humidity (everywhere even outside) and or having a shower.

@mattdm

I guess I could do that by having a separate automation with that trigger and which disables this automation? But that seems clunky

It can be a bit clunky even if you have it in the one automation as you could have 2 triggers fighting one another. You would need to have your conditions set correctly. If your looking for a seperate automation to do this then try my Temperature Control Exhaust Fan. Even though is says temperature it will work with humidity.
