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.

Would a battery powered smart switch be an option?

Hit the switch and let HA do a command series.

That's a fallback option, but I try to automate my home whenever I can and not perform manual tasks. I know my groggy morning self is forgetting to even hit this simple switch.
