Illumination system and method for maintaining a common illumination value on a release command sent from a keypad

An illumination device apparatus, comprising:

• communications interface circuitry;
• memory circuitry;
• and
• illumination device control circuitry communicatively coupled to the communications interface circuitry and to the memory circuitry, the illumination device control circuitry to:
• receive, via the communications interface circuitry, a first signal having a first temporal duration, the first signal including data representative of:
• a target output intensity value, the target output intensity value indicative of a change in an output illumination intensity provided by each of a plurality of mesh-networked illumination devices from a current illumination output value to a target illumination output value;
• and
• a mask value greater than or equal to a temporal duration of the greatest communication latency between the mesh-networked illumination devices;
• communicate, via the communications interface circuitry, the received data representative of the target output intensity value and the received data representative of the mask value to at least one other of the plurality of mesh-networked illumination devices;
• and
• cause a change in the output illumination intensity of the illumination device to achieve the target illumination output value over an adjustment period less than or equal to a defined temporal duration plus the mask value.

A non-transitory, machine-readable, storage device that includes instructions that, when executed by illumination device control circuitry disposed in one of a plurality of mesh-networked illumination devices, causes the control circuitry to:

• receive, via communicatively coupled communications interface circuitry, a first signal that includes data representative of:
• a target output intensity value, the target output intensity value indicative of a change in an output illumination intensity provided by each of the plurality of mesh-networked illumination devices from a current illumination output value to a target illumination output value;
• and
• a mask value greater than or equal to a temporal duration of the greatest communication latency between the mesh-networked illumination devices;
• communicate, via the communications interface circuitry, the received data representative of the target output intensity value and the received data representative of the mask value to at least one other of the plurality of mesh-networked illumination devices;
• and
• cause a change in the output illumination intensity to achieve the target illumination output value over an adjustment period less than or equal to a defined temporal duration plus the mask value.
