How does sleep mode affect autonomy?
Sleep mode is a device configuration that changes the device into a special state, sleep mode, at a pre-defined time window each day. In sleep mode, the device will still function and remain connected to the internet transmitting health information and receive SRF updates. However, during sleep mode the BNL will be forced OFF regardless of it’s previous setting. It doesn’t matter whether the primary color is red, double-red, NWS, etc. the light will be force-set to OFF during the sleep mode period. Likewise, purple and pier lights are also disabled (OFF) during the sleep period. In other words, all lights within the BNL are turned off for the duration of the configured sleep mode.  When the device wakes from sleep mode based upon it’s configured wake time, the light will revert back to whatever settings the primary, marine, and pier light were set to. If the previous setting before waking was NWS it will set itself to the most recent SRF, not the SRF before it entered sleep mode. In other words, the device will be up-to-date with the most recent SRF even during sleep mode.  Note: The BNL primary, marine, pier lights can be changed in sleep mode but will remain OFF until it wakes. This is useful to set the lights just prior to parking opening hours for the day.
