A simple Python API for controlling LED bulbs compatible with the Zengge protocol. This covers a wide range of bulbs, including the Flux Bluetooth bulbs.

This will connect and set the bulb to full red, no green and no blue.

import zengge

bulb = zengge.zengge("00:21:4d:00:00:01")
bulb.connect()
bulb.set_rgb(0xff, 0x00, 0x00)

This will set the intensity of the warm white LEDs to 50%

bulb.set_white(0x80)

This will turn on the white LEDs at the same time as the colour LEDs (note that this may result in a small quantity of flickering during colour changes)

bulb.set_rgbw(0xff, 0x80, 0x10, 0xff)

This will turn the bulb on

bulb.on()

This will turn the bulb off

bulb.off()

Get a list of the current red, green and blue values

(red, green, blue) = bulb.get_colour()

Get the current white intensity

white = bulb.get_white()

Get aboolean describing whether the bulb is on or off

on = bulb.get_on()

Note that this has been written against a specific bulb, and may misbehave on some other bulbs that speak a similar protocol. Please get in touch if you have a bulb that partially works with this code.

The set_rgbw() mode appears to bypass a great deal of the bulb's normal functionality - for instance, turning the bulb off and then on will not restore the state programmed by set_rgbw(). Further, calling set_rgbw() while the bulb is still fading up from an on() command will not have the desired effect.
