Device Status

ChirpStack Network server supports periodically requesting the Device Status, using the DevStatusReq mac-command specified by the LoRaWAN® protocol. A device will respond to this request by sending its battery status (if available) and its demodulation signal-to-noise ratio in dB for the last successfully received request.

When the Device Status is available, it will be exposed to the application-server on each received uplink payload.

Device Status battery

  • 0 - The end-device is connected to an external power source
  • 1..254 - The battery level, 1 being at minimum and 254 being at maximum
  • 255 - The end-device was not able to measure the battery level

Device Status margin

The margin (Margin) is the demodulation signal-to-noise ratio in dB rounded to the nearest integer value for the last successfully received DevStatusReq command.
