Systems, master node-based apparatus, and methods are described for enhanced monitoring for an event candidate within a wireless node network. Such a system may include a low-level ID node and a mid-level master node. The master node receives a first group of signals, and then detects if the ID node is broadcasting with a cycling broadcast RF power profile setting, receives a second plurality of advertising signals from the ID node also broadcast with this setting. The master node then determines a first average of an observed parameter for the first advertising signals within a first window of time commensurate with the cycling period and a second average of the observed parameter for the second advertising signals within a second window of time commensurate with the cycling period. The master node then identifies and reports the event candidate when a comparison of the first average and the second average indicates a threshold observed change relative to the ID node.
