Aqara's IEEE registrant is "Lumi United Technology Co., Ltd," which holds 2 MA-L blocks — 18:C2:3C and 54:EF:44 — based in Shenzhen (Nanshan District), China. These OUIs appear on smart-home hubs and gateways, sensors (motion/contact/temperature), smart switches, cameras, smart locks, and Zigbee/Thread/Matter devices. Lumi United was founded in 2009, the Aqara brand was established in 2016, and it has Xiaomi-ecosystem ties. The key analyst point is the Zigbee-hub-vs-IP-device angle: many Aqara devices are Zigbee (not directly IP) and connect via an Aqara hub that carries the network MAC, while Wi-Fi Aqara devices (cameras, hubs) may surface under Lumi's OUI or a Wi-Fi chipset vendor's OUI. For triage, a Lumi OUI (18:C2:3C or 54:EF:44) is almost always an Aqara hub/gateway or a Wi-Fi device; the Zigbee sensors behind it won't show their own IP MAC, so inventory the hub, not each sensor.
