A method for detecting a movement path in a monitored environment generates a first movement path record by collecting first node information for each of a first series of nodes including at least one of a sensor ID or a device ID, and a trigger time. The method further determines a first movement path total duration time from a difference between a time of the ending node and a time of the starting node of the first series of nodes. The method further stores the first movement path record and subsequently compares a second movement path record with the first movement path record by comparing the first node information with second node information for each of a second series of nodes of the second movement path record, and the first movement path total duration time with a second movement path total duration time. The method determines a similarity value between the second movement path record and the first movement path record based on the comparison and detects a movement path based on the determined similarity value.

Movement path detection for anomalies and patterns from sensors in a home or other environment

Systems and techniques are provided for presence and directional motion detection. Signals may be received from a sensor positioned in a structure. An indication of directional motion may be generated based on the signals from the sensor. The indication of directional motion may be generated without using signals from additional sensors. A control signal for a device in the structure may be generated in response to the indication of directional motion. The control signal may be sent to the device in the structure to be implemented by the device.
