Wi-Fi flood sensor, no local siren?

The Shelly Flood answers with the stronger owner reviews and broader smart home integrations. The X-Sense 2-in-1 Wi-Fi Water Leak & Freeze Detector is the louder, better sealed water leak sensor with a 5-year warranty; the Shelly Flood is the one that actually joins Alexa, Google Home, SmartThings and Home Assistant.
