1. A lighting system, comprising:
a wake-up light source to emit a wake-up light beam;
a plurality of luminaires located in a space, wherein a respective luminaire comprises:
an illumination light source to emit illumination lighting for the space;
a light sensor to detect light;
a wireless transceiver configured for wireless communication;
a memory;
a processor coupled to the light sensor, the wireless transceiver, and the memory; and
wake-up programming in the memory, wherein execution of the wake-up programming by the processor causes the respective luminaire to:
detect a plurality of light measurements above a light threshold, wherein detecting the plurality of light measurements above the light threshold comprises:
measuring, via the light sensor, the plurality of light measurements; and
based on the plurality of light measurements, identifying a sequence of excess light levels;
determine whether the plurality of light measurements are in accordance with a pattern by:
comparing, the sequence of excess light levels with a wake-up sequence; and
determining that the comparison of the sequence of excess light levels satisfies the wake-up sequence by:
transitioning from an idle state to a ready state which is a first ON cycle based on a first flash from the wake-up light beam that satisfies a minimum ON cycle time and a maximum ON cycle time;
once in the ready state, waiting for a minimum timeout and a maximum timeout for a first OFF cycle;
upon the light sensor being flashed again by the wake-up light beam, transitioning to a set state that is a second ON cycle; and
upon the wake-up light beam being turned off in a second OFF cycle, transitioning to a go state, wherein the go state indicates the wake-up light beam flashed twice and off within a set time of the first and second OFF cycles; and
in response to determining the plurality of light measurements are in accordance with the pattern, enter a beaconing mode during the go state.
