Some Notes

Color

The Wiz bulbs strongly distinguish between RGB color modes and Kelvin color modes, the latter being significantly brighter. Unfortunately, HomeKit is not very good at handling both at the same time, yielding weird errors if you try to add both characteristics.

Luckily, even if we only enable the color mode, we still get a nice temperature picker. Problem is, the color temperature is given in standard HSV. As such, this app will try to guess which one to best use given a color, and you will notice some significant brightness variance switching between a "temp" hue and a "color" hue.

In particular, since the Wiz bulbs only support up to 6500K, this means that only the top-ish half of the temperature picker is actually bright

Mostly built for my own personal use - so no active development. Feel free to fork and contribute.

How bulbs are discovered

Make a UDP broadcast to port 38899 with the following content:

{"method":"registration","params":{"phoneMac":"<my_mac_address>","register":false,"phoneIp":"<my_ip_address>"}}

You will get a response on port 38900 with the following content:

{"method":"registration","env":"pro","result":{"mac":"<light_address>","success":true}}
