It’s a tolino vision 2. Technically, it runs android 4 under the hood, but I would need to tinker with it via adb to run something else, and the small storage space available makes this not so appealing. I’d prefer to leave the complexity to the server and do the reading inside the browser in the ereader.

That’s an interesting setup, but my ereader probably doesn’t support the tinkering needed to install syncthing on it (it’s a refurbrished tolino vision 2) and the available memory is too low.

I will check them both, thank you. I don’t think my device supports koreader, but maybe I can read directly from the browser.
