Here is an example of what I started doing with dewpoint:

This is outside, but I have also made sensors for dewpoint calculations inside the house.
I found that dewpoint is a better judge of what is ‘humid’.
There is also the ‘Feels Like’ method which is effectively similar.
As you can see below, that with 80% Relative Humidity outside that with the dew point at 41F it still feels dry outside.
I initially started with the full dewpoint equation but HA didn’t like to do all the math with the logarithms too well, so I went with the simplified equation which is good enough.
