A microwave motion detection system and lighting applications. Certain types of lighting devices turn on / off and may respond to certain triggers (e.g., motion-activation, dusk-to-dawn, etc.), etc. Such lighting devices may be battery powered and have minimal on-board circuitry. Coordinating these lighting devices together to provide zoned lighting functionality has not been commercially successful. Various aspects of the present disclosure are directed to “smart enough” lighting solutions. Smart enough lighting solutions may include link-based connectivity that enables coordination between peer lighting devices. The decentralized system may enable groups of smart enough lighting devices to communicate salient events (triggering conditions and operational parameters) across a mesh network, without centralized coordination. For example, each of the smart enough lighting devices may use point-to-point communication protocols to directly communicate with its peer devices, relaying information throughout the group.
