Aqara Presence Switch H2 US combines a wall light switch and mmWave presence sensor in one device. It is intended for spaces where lighting should respond to actual occupancy, including situations where a person remains relatively still.
Three hardware variants

Thread, Zigbee and mmWave
The device supports Thread and Zigbee operating modes. The source product record notes that Aqara may expose more advanced presence capabilities through Zigbee, while the Matter feature set can depend on the destination ecosystem.
Vietnam pricing
The AQARA 2026 source currently used by the project does not contain a confidently matched WS-K22D / WS-K03D / WS-K04D entry, and the source review did not find a sufficiently reliable Vietnam retail listing for the exact Presence Switch H2 US family. The website therefore keeps the price as Contact rather than borrowing the price of the standard Light Switch H2 US.
Can H2 US detect a person who is sitting still?
Yes. The integrated mmWave sensor is designed to detect presence more reliably than a conventional PIR motion sensor in low-motion situations.
