Technical specifications for the Aqara MCCGQ11LM identify the use of a Silicon Labs EFR32 series System-on-Chip (SoC), which enables a report latency of approximately 15ms. Performance metrics indicate that these sensors are highly efficient, maintaining operation for up to 2 years on a single CR2032 cell. The hardware utilizes the Zigbee protocol, though standardized testing reveals a tendency for the device to remain static with its initial parent router, which may require manual re-pairing if the network topology changes significantly.
Material analysis confirms an ultra-miniature housing, making it the smallest footprint currently available in the Zigbee category. The mechanical reed switch is a high-tolerance component designed for rapid state changes. Mounting is restricted to adhesive applications, which may limit use on high-vibration surfaces or heavy industrial doors.
Aggregated data suggest that for maximum stability, these units should be paired with a Zigbee 3.0 coordinator that supports high-frequency polling.
Functional capabilities are most reliably accessed via an Aqara Hub, though compatibility with advanced local coordinators (ZHA/Zigbee2MQTT) is confirmed via community logs. The device operates as a Zigbee End Device and does not function as a mesh repeater.
The Aqara Zigbee Wireless Door and Window Sensors provide a low-latency alternative for users prioritizing a minimalist aesthetic over broad routing flexibility.
Within the contact sensors classification, this unit is recognized for its high-efficiency silicon and compact form factor.
