sunset
The sunset function determines the Coordinated Universal Time when the sun just sets below the horizon.
sunrise
The sunrise function determines the Coordinated Universal Time when the sun just rises above the horizon.
sundiagram
The sundiagram function creates an illustration of the sun path over the year for a specific geographic location.
suntime
The suntime function calculates the Coordinated Universal Time or local time for a given sun position and geographic location.
huename
The huename functions allows it to rename Philips HUE devices.
hueadd
The hueadd function adds Philips HUE devices to a HUE bridge using their device ID.
huesearch
The huesearch function looks for new Philips HUE devices and adds them to a specified HUE bridge.
hueset
The hueset function allows it to alter the state of Philips HUE devices.
huecon
