1. An apparatus to detect multiple wearable meter devices, the apparatus comprising:
interface circuitry to:
obtain primary data from a first meter and a second meter, the primary data including at least one of: (a) acceleration data and (b) short-range wireless communication data; and
obtain secondary data from the first meter and the second meter, the secondary data including at least one of: (a) location data and (b) audio data;
comparator circuitry to:
determine one or more primary factors based on the primary data, the one or more primary factors to include: (a) a correlation coefficient based on the acceleration data, and (b) a difference between connected device sequences based on the short-range wireless communication data;
determine one or more secondary factors based on the secondary data, the one or more secondary factors to include: (a) a distance between the first meter and the second meter based on the location data, and (b) a difference between the audio data; and
model executor circuitry to determine, based on the one or more primary factors and the one or more secondary factors, whether the first meter and the second meter correspond to duplicate wear.
