In some implementations, the computing system determines (1306) that the particular room is occupied based on the detected motion. In some implementations, the computing system utilizes a data processing module to make the determination (e.g., data processing module 9322 and/or radar processing module 9324). In some implementations, the computing system categorizes (e.g., using radar processing module 9324) the detected motion to determine if the motion is associated with a living entity (e.g., a person walking) or a non-living object (e.g., a fan spinning). In some implementations, the computing system determines that the particular room is occupied in accordance with a determination that the detected motion comprises motion of a living entity. In some implementations, the computing system transmits the radar data to a server system (e.g., server system 508,
