Wake-up behavior while on battery

Normal mode

Standard configuration

  • 12 hours upload interval, until the battery level is 35%.

  • 24 hours upload interval until the battery is 10%.

  • 48 hours upload interval for 10 times. Following that the device shuts down all cellular communication to preserve battery and stores measured data in memory until the device is connected to power again

Low power configuration (Dulas)

  • 24 hours upload interval, until the battery level is 35%.

  • 46 hours upload interval until the battery is 10%.

  • 98 hours upload interval for 10 times. Following that the device shuts down all cellular communication to preserve battery and stores measured data in memory until the device is connected to power again

During excursions

If a logger on battery crosses a boundary, it will start to wake up every 10 minutes for 1 hour, then every 1 hour for 5 hours and after that it will go into its normal wake-up routine.

Button functionality

To prevent users to be able to drain the battery too fast, the button press can only trigger a data upload a maximum of once every 1 hour. I.e. if the button is pressed the next possible button triggered upload can happen in no less than 1 hour.

The button press cannot trigger a wake-up once the battery goes below 3.7V which is around 25% in the UI
