A technique for saving power in a tag that is operationally connected to an asset involves using telemetry data to enter an appropriate power state. An asset tracking system according to the technique can make use of context to better track assets to which power-saving tags are operationally connected. Secure tag configuration techniques and asset-agnostic tags are described. Location-agnostic tags are also described.
