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.


If it’s an electric shower, you can do what a salamander pump does and add some detection wires on the shower box’s on-switch. I appreciate you don’t want wires around the shower but it’s a fully direct “is the shower on” detector and the wires are technically in the shower rather than around it.
Electric shower…?
A shower that takes cold water from the mains and heats it with electricity. Common as muck in the UK.
That makes sense. I’m not sure we have those in the US. It does sound a bit like a euphemism for an execution method haha

I wanted an electric diverter but it was way too expensive so sadly I have to stick with manual buttons (it’s thermostatic though so I don’t mind)
