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.

@batshit I use a derivative of a humidity sensor, it works well enough and is really simple to set up.

    Would it detect as soon as I start the shower or will it have a minute lag? Like I said, I want the automation to kick in as soon as I start.

    I'm also using a humidity sensor in my custom bathroom setup. It really detects the start of a shower quite fast. 10s to 30s I'd say, depending on the humidity before starting the shower.

    But also I have a very small window-less bathroom, so you mileage may vary.
