Control Xiaomi Mi Yeelight (RGB) with shell scripts. Should work under any recent Linux with a bash or zsh - sorry, don't know if that works under Windows/CygWin or Macos - you might need to rewrite the last line in the yeelight.sh script (e.g. by pipeing the output to netcat).

You need to connect the light using the Yeelight app (or using any other appropriate way) to your network. Then enable Developer Mode (or LAN Control Mode in the current version of the app) for the light. This setting may need to be reset after a firmware update. You should also make sure that your DHCP server always assigns the same IP address to the light.
Now edit the yeelight-ips file and enter the IP address of each light you have, separated by a space.
Each of the yeelight-*.sh scripts has a specific function that is hopefully quite easy to guess from it's name. All the scripts call the yeelight.sh script that really does the job. Each script requires several parameters - calling them without any will give you a usage prompt. All scripts require the ID of a light - this is the position of the light you entered in the setup part. The first light has the ID 0.
Switch on (to last used values)
./yeelight-scene.sh 0 OnSwitch on using 4300 Kelvin
./yeelight-scene.sh 0 4300Switch on Rainbow
./yeelight-scene.sh 0 RainbowSwitch on Disco
./yeelight-scene.sh 0 DiscoSwitch on Disco with 120ms
DISCOSPEED=120 ./yeelight-scene.sh 0 DiscoSet brightness to 50%
./yeelight-brightness.sh 0 50Set RGB color to BLUE (using absolut number, decimal and hex triples)
./yeelight-rgb.sh 0 255
./yeelight-rgb.sh 0 0,0,255
./yeelight-rgb.sh 0 x0,0,ffSet hue (hsv) to 32 (yellow) with 80% brightness (of that color - 0 means full white)
./yeelight-hue.sh 0 32 80Set color temperature to 6500 Kelvin
./yeelight-colortemp.sh 0 6500yeelight-redshift.sh is a script that allows your lamp to change color temperature simultaneously with your monitor if you use redshift. Just like redshift, this script eases strain on your eyes if you use your computer at night. To use this script you need to copy ./samples/yeelight-redshift.timer and ./samples/yeelight-redshift.service to /etc/systemd/system/, change scrip location in yeelight-redshift.service. Then run sudo systemctl daemon-reload, sudo systemctlt enable yeelight-redshift.timer, sudo systemctl start yeelight-redshift.timer.
You can also change some values in yeelight-redshift.sh if you need warmer color.
For the script to work you need to have redshift installed.

I am personally using this scripts on a Synology NAS with a running HA-Bridge.
Since the scripts don't require any additional tool or access rights you can just execute them directly from the HA-Bridge.
Make sure the scripts are executable (chmod +x *.sh) and either you are using the full path or put them somewhere inside $PATH, for example /usr/local/bin/.
I have setup different scenes as devices for the same light. There is a bedroom device which can be switched on/off and use the dim feature - this is just a normal setup. And there is also a sleep and a rainbow device that addresses the same light to apply this scenes.
yeelight-disco.sh is a wrapper that only accepts one value - I use ${intensity.percent} from HA-Bridge. There is some math done with that value to fit into the 2-99% range (Strange: I can't tell Alexa to use 1 or 100%) and still have some 'disco-speed'. Adjust to your needs.
