A Linux compatible application for controlling the Elgato Key Lights

Keylight Controller

This is a desktop application to control Elgato Keylights.

Why?

As you may very well be aware, there are already desktop applications for Elgato Keylights, however like most Elgato/Corsair software there are not Linux alternatives, and since I daily drive linux, not having a way to control the lights via my desktop can be quite annoying. So I created this to solve my inconvience.

Installation/Run

At this time the application is distrubuted via an AppImage for maximum distro compatiblity so make sure you have AppImage installed/configured before hand (Most distros have AppImage installed by default). I am working on adding distro specific releases (deb/rpm) in the future.

To download head here and download the Keylight_Controller-x86_64.AppImage file.

keylight-control's Issues

The application isn't showing control anymore

Keylight Control worked very fine for 30 minutes after install . The i created a launcher entry for the AppImage and started it maybe a few times and had more than one instance running.
Now (even after system reboot) the application window stays empty, see screenshot.
At the same time i can still control the light via iOS app.

When starting from CMD i get following error

'/home/user/Apps/Keylight_Controller-x86_64.AppImage'

This is the launcher code, but this should't be the problem

AppImage doesn't work with newer nodejs versions

• Ubuntu 22.04.1LTS
• installing node(js) 14.x
• trying to start Keylight_Controller-x86_64.AppImage simply opens a terminal with the nodejs prompt and warnings.

Light Strip Support

Add support for the newly released RGB Light Strip.

Everything seems OK but controls do not work - tool is using wrong ip

Hello

I've tried the appimage and everything seems to be there:

• The window appears, the icon is in the tray
• It shows the correct light (Elgato Key Light Air #392C)
• The Brightness & Temperature as well as Off/On button is there

But pressing / using any of the controls simply does nothing

The light is seen with avahi

Server version: avahi 0.7; Host name: Ganymede.local
E Ifce Prot Name                                          Type                 Domain
+ enp8s0 IPv4 Elgato Key Light Air 392C                     _elg._tcp            local

I've tested with the keylightctl CLI tool and that one works, so communication between the computer and the light is happening
(it can control the light without issue)

I've whipped out Wireshark and I found that for some reason, your app is using the wrong IP (it's trying the IP of a WIFI Access Point I have) while keylightctl is using the correct IP.

It's not connecting, just shows the window with nothing in it.

I have an elgato key light and even after resetting it still won't show up, I can connect to the wifi network but that still doesn't make any difference. I'm on pop-os 20.10 with an Nvidia 1050 ti on 510.54 drivers, It's probably just some stupid setting on my end but if you don't mind any help would be greatly appreciated.

Buffer() is deprecated

Thanks for a nice piece of software!

Would it be possible to fix this issue? Or am I doing something wrong? No GUI appears when running the code.

Thank you ❤️

This worked first time, absolutely no hassle. Thank you for publishing this tool ❤️

Command Line Support

Is your feature request related to a problem? Please describe.
I'm wanting to link this up to a StreamDeck - is there a way to interact with the app without hacking it for command line usage?

Describe the solution you'd like
A simple CLI client, or even a client we could hook into.

Describe alternatives you've considered
None at this stage.

Manual IP/Hostname Registration

Add support for manual adding of key lights for scenarios where Bonjour is not working/unable to find the keylight.
