The main thing I have learned after switching to Linux full-time is that weird, proprietary hardware like this is almost never a good idea, for many reasons. It’s very easy to make labels for keys if you really want to, and if you need more functionality, having more buttons instead of layers is always going to be faster to learn and use. Especially if you are trying to use this as a home automation interface, it’s probably a better idea to have either a touch screen or a separate screen and keypad.
Sure, this thing looks nice, but in a couple years (at most) it will be e-waste.
I was able to get my invidious instance back up and running for the last week or so using the instructions in the invidious docs, but this process is a bandaid, and I expect it will be shut down again soon, unfortunately.
