Minoston Countdown Timer Switch, WiFi Timer Switch for Bathroom Fans and Lights, 10-20-30-60 min/2-4 Hour, Neutral Wire Needed, 15A, 1/2HP/120VAC, ETL Listed, White (MT10W)

I do use this one https://a.co/d/0e4TWwmF The integration with HA is really bare and I can only turn on and off. But it does sabe the last timer you used. So I have a separate switchbot humidity sensor and I created an automation that if the bathroom reaches 60% humidity (random number, no specific reason why I picked this number) it turns on. After the timer reaches the end it turns off by itself. And if it still above 60% it will run again.
