Look into the arr and usenet

You can use openrazer with any frontend

The setup is fairly involved and not super beginner friendly however I finally came across and finished to flash my robot a few weeks ago and i don’t notice any difference vs the stock firmware when using home assistant, beside the fact that its no longer connecting to all these random servers in China. It really is a wonderful project!

Just use valetudo in this case it works great

Same, btw
