Review on 🌊 Enhanced Everspring ST812 Flood Detector with Z-Wave Wireless Technology by Chris Fisher

Easy to install, easy to set up with the Samsung SmartHub and works and does as advertised. Sends a triggered alert to my phone via Samsung's SmartThings app, which also sends a text message to my wife. It has been installed for several weeks, there are no false alarms. The sensor has two small metal rods spaced half a centimeter apart - they need to be underwater to work. Seems like a good design to avoid false alarms and only fire when wet.
