/[SENSR version]/settings/sensor-ext

• Get an actual configuration settings of the desired sensor.

• If you do not pass any sensor-id, this command returns the full sensor IDs in SENSR. You can filter this list by passing in node-uri to filter out only the sensors beloning to a specified algo node.

• Parameters
  • sensor-id : ID of sensor.
  • node-uri (optional) : ID of algo node.
• Return code
  • 200 OK
  • 400 BAD REQ
