I am using booklore for the same reason as you and it works very well. The only feature I’m missing is highlighting, but I can live without it.

However, the image quality of those displays is usually worse compared to home displays. This is from a technical who works with these products.

I don’t remember if it was next or owncloud, but one of them was making a rewrite in go. I’m I’m no rush to jump into it, but keep a eye on it.
