Before connecting to Apple HomeKit or enabling skills in Google Home and Alexa, please pair Zigbee water leak sensor with an Aqara Hub. [Proximity] To ensure a stable connection, keep the Aqara Water Leak Sensor within 400 inches (approximately 10 meters) of the Aqara Zigbee Hub, and place the hub within the same range of your Wi-Fi router. Ensure both are connected to the same local area network (LAN). [Drip and Leak Detection] Equipped with highly sensitive probes that detect water levels as low as 0.5 mm (approximately 0.02 inch), this water leak detector instantly sends alerts to your phone and triggers the local alarm on the Aqara Hub whenever a leak is detected.
