Automation that gets triggered on calculated value

Configuration
1

I have a bathroom fan that comes on if the humidity is above 69%, and turns off when below 56%.

The only problem is if the fan is manually triggered and the humidity is already under 56%. The bottom 40% trigger is there to solve this problem. It works almost all the time, except if it is very dry winter time.

Is there a better approach besides setting a secondary, lower value to trigger?

I know I can calculate the average of other entities, all the humidity sensors in the house, let’s call it h. I would like to set the trigger to say h+5. So, the automation is triggered f the bathroom humidity crosses (average house humidity+5)%.

How would I do this?
