Performance metrics for the Aqara SJCGQ11LM indicate a high-precision Zigbee end-device architecture. The unit utilizes a "sleep-and-wake" duty cycle to maximize the efficiency of its CR2032 coin cell, with a projected battery life of approximately 24 months. Technical documentation confirms an IP67 rating, certifying the chassis for submersion in up to 1 meter of water for a 30-minute duration.
Material science analysis reveals the use of gold-plated probes on the base of the unit to ensure consistent circuit completion upon water contact. When triggered, the device transmits an ias_zone status change via Zigbee 3.0 protocols. Technical specifications show a latency of less than 200ms between initial contact and signal transmission to the local coordinator.
Network integration protocols include:
- Local Execution: Operates without internet connectivity when paired with a local Zigbee coordinator.
- Aggressive Polling: Utilizes proprietary Zigbee implementation details for status monitoring.
- Zigbee Mesh Dependency: Requires proximity to powered repeaters for optimal signal gain.
Aggregated data indicates that battery voltage reporting may be sensitive to cold environments, potentially resulting in premature low-battery alerts in uninsulated locations. Reliability is contingent upon the strength of the local Zigbee mesh, as the compact internal antenna has limited range without neighboring router devices.
For properties where Zigbee signal penetration is insufficient, the YoLink LoRa-based system offers a significantly higher communication range. YoLink Water Leak Detector Kit with Hub and Sensors
