  • OK, assuming your switch is also smart

    Option 1: long-press/double function turns on both light and fan, that triggers an “I am going to shower” 5 minute delay where a humidity sensor senses when it is over and keeps the fan on until humidity is stabilized with the rest of the house.

    Option 2: get a smart flow meter instead of a smart valve. Then you have useful statistics for shower water usage in addition to an instantaneous status. This has the side effect of the mood lighting turning on “late”

    Option 3: get one or make an esphome + LD2410S on battery or plugged in close by, nobody goes in the shower for more than like 10 seconds without showering

    Option 4: Time of Flight sensor outside of the shower pointing in to tell when the door/curtain is closed. If the ToF sensor is (for example) between 1.1m and 1.2m, the door/curtain is closed


  • Spinning up and down hard drives repeatedly drastically reduces their lifespan though. Once a day or so, fine, but if you set a 30 minute idle time or something and it spins them down a dozen times per day, you are putting acceleration forces on the drive many more times than intended.

    If you have to buy a new HDD twice as often because you spin it down, any financial or environmental savings is instantly negated and in the end it is much, much worse in both respects.
