keylightctl

keylightctl

Controls Elgato Key Light Air devices from the terminal: get status, turn lights on and off, and set brightness and temperature, either with subcommands or in a full-screen interactive TUI.

Lights are read from ~/.config/keylightctl/config.json (respects $XDG_CONFIG_HOME; override with -config):

{
  "lights": [
    { "name": "Left",  "ip": "192.168.2.164:9123" },
    { "name": "Right", "ip": "192.168.2.165:9123" }
  ]
}

keylightctl status           # show each light's status
keylightctl on               # turn on (-b brightness, -t temperature, -l light)
keylightctl off              # turn off (-l light)
keylightctl -version         # print version

Run keylightctl with no arguments for the interactive TUI:

Build and install with make:

make build        # ./bin/keylightctl
make install      # to ~/.local/bin (override with BINDIR=)
make uninstall    # remove from BINDIR
