About device power saving management

Many Kontakt.io devices have power-saving options that conserve power to extend battery life. Power saving can be managed by device movement, a 7-day hourly schedule, a timed broadcasting sequence, or ambient light levels. In power-saving mode, a device uses less energy by broadcasting less often and turning off non-essential hardware sensors.

Movement-based Broadcasting power saving

For devices with an accelerometer, power saving is managed by movement. The device conserves battery power when it isn't moving.

• Normal broadcast (advertising) mode: when the accelerometer detects the device moving.

• Power-saving mode: when the accelerometer detects no movement for a configurable period (60 seconds by default, adjustable from 20 to 3600 seconds).

  In power-saving mode, the device settings are as follows.

  Setting	When in power-saving mode
  Hardware Sensors (thermal camera, IR emitters, LEDs, environmental sensors)	Disabled
  Kontakt.io Telemetry packet	Disabled
  Kontakt.io Location packet	Increased Interval*
  Kontakt.io Secure Profile packet	Increased Interval*
  iBeacon packet, Eddystone packet	Disabled

*The Increased Interval reduces the broadcasting rate. It is the device's current interval multiplied by three, with two limits:

• If the result is less than 2000 ms, the increased interval is set to 2000 ms.
• If the result is greater than 10240 ms (the Bluetooth maximum), the increased interval is set to 10240 ms.

Working Hours power saving

The device follows a broadcast schedule based on hours of operation in a 7-day, hour-by-hour calendar. This lets the device conserve battery power during the non-working hours you specify.

• Normal broadcast (advertising) mode: during the working-hours schedule.

• Power-saving mode: outside the working-hours schedule.

  In power-saving mode, the device settings are as follows.

  Setting	When in power-saving mode
  Hardware Sensors (thermal camera, IR emitters, LEDs, environmental sensors)	Disabled
  Kontakt.io Telemetry packet	Disabled
  Kontakt.io Location packet	Increased Interval*
  Kontakt.io Secure Profile packet	Increased Interval*
  iBeacon packet, Eddystone packet	Disabled

*The Increased Interval reduces the broadcasting rate. It is the device's current interval multiplied by three, with two limits:

• If the result is less than 2000 ms, the increased interval is set to 2000 ms.
• If the result is greater than 10240 ms (the Bluetooth maximum), the increased interval is set to 10240 ms.

Active Broadcasting Windows power saving

The device follows a timed sequence that sets how many seconds it stays "awake" and broadcasting normally. When the awake period ends, the device goes to sleep (power-saving mode) and stops broadcasting for a set number of minutes. The sequence repeats continuously.

• Normal broadcast (advertising) mode: a set number of consecutive "active broadcasting" seconds.

• Power-saving mode: a set number of consecutive "sleep" minutes.

  During sleep, a device with an accelerometer wakes up when the accelerometer detects movement, and a device with a button wakes up when a button is pressed. Either event resets the sequence, and the device starts broadcasting again when the event occurs.

  In power-saving mode, the device settings are as follows.

  Setting	When in power-saving mode
  Hardware Sensors (thermal camera, IR emitters, LEDs, environmental sensors)	Disabled
  Kontakt.io Telemetry packet	Disabled
  Kontakt.io Location packet	Disabled
  Kontakt.io Secure Profile packet	Disabled
  iBeacon packet, Eddystone packet	Disabled

Brightness Level power saving

For devices with a light sensor, power saving is managed by the ambient light level. This lets the device conserve power when the lights are off at night.

• Normal broadcast (advertising) mode: when the ambient light level is at or above the threshold percentage you set.

• Power-saving mode: when the ambient light level drops below that threshold.

  In power-saving mode, the device settings are as follows.

  Setting	When in power-saving mode
  Hardware Sensors (thermal camera, IR emitters, LEDs, environmental sensors)	Disabled
  Kontakt.io Telemetry packet	Disabled
  Kontakt.io Location packet	Increased Interval*
  Kontakt.io Secure Profile packet	Increased Interval*
  iBeacon packet, Eddystone packet	Disabled

*The Increased Interval reduces the broadcasting rate. It is the device's current interval multiplied by three, with two limits:

• If the result is less than 2000 ms, the increased interval is set to 2000 ms.
• If the result is greater than 10240 ms (the Bluetooth maximum), the increased interval is set to 10240 ms.
