Abstract
Methods and apparatus for multi-purpose metering are disclosed. An example method includes determining whether a portable device is within a vicinity of a household monitoring system based on detecting an identifier via a first radio frequency (RF) signal, when the identifier from the first RF signal is associated with the portable device, determining whether a second acoustic signal includes the identifier associated with the portable device, deactivating a media detection circuit of the portable device when the identifier is detected via both the first RF signal and the second acoustic signal, and activating the media detection circuit of the portable device when the identifier is detected from the first RF signal and the second acoustic signal is absent.
