Both watch water and freeze risk. The Aeotec Water Leak Sensor stays cheaper and better reviewed as a SmartThings and Home Assistant Zigbee disc, but it is only IP20 with a 1-year battery and no local alarm. Pick the Moen Smart Leak Detector for a waterproof Wi-Fi puck that beeps; pick the Aeotec Water Leak Sensor for a cheap leak-and-freeze Zigbee node in SmartThings.
