I would like to turn on mood lighting automatically when I’m taking a shower, what’s the best way to detect that?

  • I’ve considered humidity sensors, but that will take a while to kick in and not immediately when the shower starts.
  • I’ve also considered a water leak sensor but those are not meant to be trigger every day for a long time like 10-15 minutes. That would kill the battery, right?
  • Smart valves can kind of work, but it feels like overkill because I don’t care about the valve functionality.

I would prefer the solution to be battery powered (don’t want to be messing with too many cables around a shower), but I can’t seem to find one.

    I’m using just humidity and its working great. I put the sensor away from my sink so it isn’t triggered by washing my hands.

    This will only consider you showering if humidity goes 9% above the 1hr average humidity:

    You need a ‘Statistics’ Helper, call it “Average Bathroom Humidity” and base it on whatever humidity sensor you have. Make it “average linear” then set Max Age to 1 hour. (leave other options default)

    Make this Template Binary Sensor called “Showering”:

    {{ (states('sensor.bathroom_sensor_humidity')|float - states('sensor.average_bathroom_humidity')|float) > 9 }}

    Multiple waterproof 4k cameras pointed at the inside of your shower from every angle and image recognition by some AI that detects when a naked person enters.

    Don’t forget to use Wifi and no firewall

    You could use a classic dead man switch: Place several buttons around the whole place - basically everywhere except in the shower. Once you stop pressing any of these buttons for - let’s say - 30 seconds you can assume you’re taking a shower.
