Those wins sit alongside 2 years of battery life, richer alert options, and wider smart-home integrations. The radios differ too: Aqara Water Leak Sensor T1 has no extra long-range radio, 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 the more affordable option, so it remains the pick when that priority beats 2 years of battery life. If 2 years of battery life is on the list, the Aqara Water Leak Sensor T1 is the water leak sensor to buy; otherwise the Meross Smart Water Leak Sensor is the honest alternative.
