Power Configuration

The power config options are: Power Saving, Shutdown after losing power, ADC Multiplier Override Wait Bluetooth Interval, Mesh Super Deep Sleep Timeout, Super Deep Sleep Interval, Light Sleep Interval and Minimum Wake Interval. Power config uses an admin message sending a Config.Power protobuf.

Power settings are advanced configuration, most users should choose a role under Device Config to manage power for their device and should never need to touch any of these settings.

Power Config Valuesโ€‹

Power Savingโ€‹

If set, we are powered from a low-current source (i.e. solar), so even if it looks like we have power flowing in we should try to minimize power consumption as much as possible.

Shutdown after losing powerโ€‹

Automatically shut down a device after a defined time period if power is lost.

ADC Multiplier Override Fixes issues on Heltec v2โ€‹

Ratio of voltage divider for battery pin e.g. 3.20 (R1=100k, R2=220k)

Overrides the ADC_MULTIPLIER defined in the firmware device variant file for battery voltage calculation.

Should be set to floating point value between 2 and 4

Wait Bluetooth Intervalโ€‹

How long wait before turning off BLE in no Bluetooth states

0 for default of 1 minute

Mesh Super Deep Sleep Timeoutโ€‹

While in Light Sleep if this value is exceeded we will lower into super deep sleep

or Super Deep Sleep Interval (default 1 year) or a button press

0 for default of two hours, MAXUINT for disabled

Super Deep Sleep Intervalโ€‹

While in Light Sleep if Mesh Super Deep Sleep Timeout Seconds is exceeded we will lower into super deep sleep or this value (default 1 year) or a button press

0 for default of one year

Light Sleep Interval ESP32 Only Settingโ€‹

In light sleep the CPU is suspended, LoRa radio is on, BLE is off an GPS is on

0 for default of five minutes

Minimum Wake Intervalโ€‹

While in light sleep when we receive packets on the LoRa radio we will wake and handle them and stay awake in no Bluetooth mode for this interval

0 for default of 10 seconds

Power Config Client Availabilityโ€‹


All Power config options are available in the python CLI.

SettingAcceptable ValuesDefault
power.is_power_savingtrue, falsefalse
power.on_battery_shutdown_after_secsinteger (seconds)Default of 0 is off
power.adc_multiplier_override2-4 (floating point value)Default of 0 uses firmware values
power.wait_bluetooth_secsinteger (seconds)Default of 0 is 1 minute
power.mesh_sds_timeout_secsinteger (seconds)Default of 0 is 2 hours
power.sds_secsinteger (seconds)Default of 0 is 1 year
power.ls_secsinteger (seconds)Default of 0 is 1 hour
power.min_wake_secsinteger (seconds)Default of 0 is 10 seconds

Because the device will reboot after each command is sent via CLI, it is recommended when setting multiple values in a config section that commands be chained together as one.
