How to check if someone is in bath?

I run our master bathroom fan based on this. Have an Aeotec sensor in there and use this AVERAGE sensor to calculate the average humidity in the room:

Average Sensor

UPD: Average Temperature sensor is now deprecated. Use Average sensor instead: https://github.com/Limych/ha-average This sensor allows you to calculate the average temperature for one or more sensors over a specified period. Or just the average current temperature for one or more sensors, if you do not need historical data.

It’s available via HACS as ‘Average Sensor’ [GitHub - Limych/ha-average: Average Sensor for Home Assistant]

Hope it helps!
