I've made some Arduino code which "emulates" a SideKick device. If you can get your hands on a 10$ ESP32 and some WS2812B LEDs you're good to go!
Here's a video of my setup (the small strip in front is controlled using the ESP32):
Now, I've purchased some Philips Hue devices to see if I can make a bridge between the DreamScreen and Hue, so that Hue devices can interact with the DreamScreen the same way a SideKick does, or that you could control DreamScreen as a Hue device. And probably also MQTT support, so you can integrate DreamScreen in your favorite home automation software. Later on I might also look into adding support for Razer Chroma devices...
I've proposed to the creator of DreamScreen to (partially) open source the firmware so the community could help develop features, but he has not gotten back to me.... a bit disappointing as he seems too busy to add often requested features and fixes.
But anyway, that is for later!
The code isn't super user friendly yet, but you can have a peek here:
