The goal of ekl is to allow you to control an Elgato Key Light or Key Light Air from R.
Why would you want to do that, you ask? Because you can. No other reason. Though you could use it to flash your Key Light when your machine learning model has finished training! ;)
You can install ekl from GitHub with:
remotes::install_github("sellorm/ekl")All of the functions in ekl take an optional keylight_ip parameter.
Instead of supplying this everytime you use it, your life will be much improved
if you instead set the environment varable EKL_IP. I added mine to my local
.Renviron file.
I found the IP address for my light by running nmap 192.168.0.* in a terminal
with the light powered off and then again with it powered on and comparing the
outputs. Sorry, I can't think of an easier way!
Toggle your Key Light on and off:
ekl::toggle()Get the current state of your Key Light:
ekl::get_state()Set the state of your Key Light:
ekl::set_state("on", brightness=50, temperature=178)Brightness is a simple scale from 1-100, but the colour temperature seems to run from 143-344 for some reason. 5600 Kelvin, which is considered to be "daylight" is about 178.
Maybe at some point in the future I'll work on some conversions so the temperature can be expressed in Kelvin instead of this weird scale.
The other big caveat is that I only have a single light to test this with, so I have no idea what the behaviour might be with more than 1 light. If anyone would like to send me another, please feel free ;)
