Winner

Kidde WiFi Water Leak & Freeze Detector

$18.43

Buy on Amazon USA

Kidde wins on price, integrations, sensors, and alerts, sitting on a floor with 2x AA cells, freeze warnings, and Alexa plus Google Home. The Eve Water Guard still wins on owner reviews, weather resistance, Bluetooth plus Thread, and an alert light, stretching a sensing cable along a whole appliance run with a 100 dB siren, but it needs wall power and lives in Apple Home rather than Alexa. Choose the Kidde WiFi Water Leak & Freeze Detector for cheap, portable freeze-and-leak pucks; pick the Eve Water Guard when a HomeKit kitchen or laundry run is next to an outlet and you want cable coverage instead of several pucks.
