Accessor: services/FINDLocation


Obtain a labeled location from a WiFi fingerprint using a FIND server.

Additional documentation for the FIND API is at The basic unit in FIND for a map or a set of users is a group. This accessor will only work if the group is set to the same string as used in training.

The username input provides a consistent label for a user who wishes to be tracked by the FIND server. If you don't care about tracking, the default value is fine.

The wifi-fingerprint input should be a JSON array of the form "wifi-fingerprint":[ { "mac":"AA:AA:AA:AA:AA:AA", "rssi":-45 }, { "mac":"BB:BB:BB:BB:BB:BB", "rssi":-55 } ]

Documentation for setting up a FIND (FRAMEWORK FOR INTERNAL NAVIGATION AND DISCOVERY) server is available at The default parameters for this accessor connect to a server on The developers for the FIND project also manage a publicly available server at
