“These water leak sensors are impressive but time will tell. It's not obvious, but the "cable" like attachment greatly extends the scope of a sensor. They are very sensitive to water, only a small splash on the "cable" is instantly detected as a leak. It took about half an hour to dry out. When nearly dry you may get some flip-flopping between wet and dry for a while but this doesn't appear to happen once fully dry.”
“Simple to setup and easily paired straight to Home Assistant via ZHA integration. The extension sensor cable looks useful and it’s installed under a kitchen counter to monitor a dishwasher and sink, just in case!”
