Leak sensor prevented me from some pain!
(feddit.org)
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.
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?
