Hi, folks!
I wrote script on Python 2.7 to implement ambilight-like functional for Yeelight bulb(color). You can place bulb behind the monitor(or TV, that uses like second monitor) and run the script to make bulb colour adaptive.
How it works:
- Enable music mode
- Make a screenshot of screen (supports multi-screens)
- Do some image processing magic to detect dominant colour
- Change color of bulb to dominant colour on screen
It works with delays, but you can try it ^_^.
To install script use:
pip install yeelight-cinema
Usage:
yeelight-cinema.py --bulb_ip=192.168.1.240 --resolution_l=1920x1080
To use with secondary monitor (places right):
screen to use left screen resolution right screen resolution
yeelight-cinema.py --bulb_ip=192.168.1.240 --target_screen=right --resolution_l=1920x1080 --resolution_r=1920x1080

I hope it will be useful for somebody 
I going to keep working on it to decrease delays in future.
