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 would go for a simple humidity sensor. You just need to do a bit of data collection first to get a baseline of "what taking a shower usually looks like" and then based on that create the automation.

The only problem with that is that depending on how accurate you want it to be, you may have to wait a while to take a few measurements until it triggers the automation.

For something like mood lights I would just use a ZigBee switch if I'm being honest though.
