Add 5 years of battery life, richer alert options, and a 2-year warranty and the gap is structural, not a sale price. The radios differ too: YoLink Water Leak Sensor 1 uses LoRa (YoLink hub required), and Meross Smart Water Leak Sensor uses Sub-1G (Smart Wi-Fi Hub required). Meross Smart Water Leak Sensor keeps an on-device alarm and wider smart-home integrations, so it remains the pick when that priority beats IP68 weather resistance. Shop the YoLink Water Leak Sensor 1 unless an on-device alarm is the only thing you came for, in which case the Meross Smart Water Leak Sensor is enough.
