ChirpStack 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 through the configured integrations.
- Margin: the demodulation signal-to-noise ratio in dB rounded to the nearest integer value for the last successfully received DevStatusReq command.
- External power source: if the device was powered by an external power-source.
- Battery level unavailable: if this is set to true, no battery level is available.
- Battery level: battery level as percentage.
