What's the best way to detect when I'm taking a shower? (lemmy.world)

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.

You could also use the drain pipe if the actual water pipe is harder to reach. It would even work against false positives (I can clearly hear the washing machine letting in water through my water pipes)…
