Had a leak under the sink in our kitchen. I don’t want to imagine what this would have meant on a larger scale, compared the 20€ I spent on the sensor and the 10mins it costed me to install it.

I'm curious. Like what?
A door opening contact sensor.
You can buy these at around the same price or less, so no point in doing that
Aqara have good door and window sensors too
Seeing how much liquid you can pee?
Edited my post to include a link - someone used it for a bed occupancy sensor: https://www.homeautomationguy.io/blog/making-my-own-bed-sensor
Some days I don't wet the bed, how will it recognize my presence without a steady stream of moisture?
