Dynamic fan speed automation in response to a secondary humidity sensor

Configuration
2

Thanks to @Lionel_Glitchy on his post here, I managed to put together some automation that makes sense.

This is still under test and I will report back once I have the final version.

As explained by @Lionel_Glitchy, to use this you’ll need to create some helpers so you don’t have any parameters hard coded.
