Remarkable Output Device

wedgen · 11-03-2017, 09:16 PM

I just got the remarkable and wanted to start exporting books to it. How can I create a custom output device that supports the resolution of the remarkable?

There is no need, just choose the Tablet output profile.

Is there a way to connect and manage the Remarkable directly from Calibre? Thanks.

That only affects resizing of images; it doesn't help with the Remarkable being seen as a device.

When I use Tablet output, the images are all screwed up and cause the reader to do really weird things. Anyone had luck converting kindle books to epub? Many of them convert fine others no so much, and usually its due to the images.

Old thread, I know, but makes sense to expand on it...

The reMarkable does not connect as USB disk (or MTP) device. Here is what I know so far:

Remarkable company supports only transfer of books via their cloud app. You "import" files from your desktop, it sends it to the cloud, optimizes it to the device spec (?) and pushes it to your device.
The only alternative to the cloud is SSH. When the device gets connected to a computer via the USB cable, the reMarkable becomes a USB network device, which accepts SSH connections (by root only). Now data can be transfered via SCP/SFTP.

However, you can not simply drag and drop to the filesystem, since they use a more "database" like approach (all books get additional metadata files and all ends up in a single, mostly flat, directory structure). Here is how two ePub files end up on the filesystem (note also, that the filenames get replaced with UUIDs):

The thumbnail files seem to contain thumbnails for those pages, which have already been opened.

Remarkable states support for PDF and ePub, but ePub support is not real. What happens, instead, is, that the ePub gets converted to PDF and then the ePub and the PDF get pushed to your device. The reader can not display the ePub, but only the PDF. ePub conversion is slow on the device.

An output device for Calibre would need to implement

SFTP transfer with the device
handling of the filesystem layout and creation of the metadata and thumbnail files
keep a mapping between the device's "library" and Calibre's
as bonus: do the conversion of ePub into PDF with Calibe before transfer

That's all I know for now. There is a whole bunch of utilities, that try to make life easier at github.com/reHackable/awesome-reMarkable, but no Calibre device, so far.

Tried myself at it: I created (more like POC-ed) a driver that sees remarkable's cloud as a device and push/pull books from it.
I used https://github.com/subutux/rmapy as a base to interact with the cloud, and tried to fill all the gaps I could find. But I think calibre don't really expect to interact with devices through the cloud.

Anyway it's full of missing features (the API does not provide authors, file size etc without having to download the file), full of `print` statements and probably full of bugs, but might be enough for simple tasks such as uploading/downloading books.
You'll just need to install a plugin from a zip file and register it through the driver's configuration. (name is Remarkable 2 Cloud Interface, even though I suspect it will work with first gen too)

Here goes the link with the source code and the zip file for the driver:

Hope it will help!

Drag and drop to the Browser Window seems to be the only way to get files on the Remarkable on Linux:

Create directories/folders on the Remarkable GUI, before or during connection.

1) Connect a USB cable.
2) Enable USB Web in Storage Menu
3) Open 10.11.99.1 on your Browser (Waterfox works)
4) Drag and Drop a PDF from File Manager to the Browser window.

Handwriting conversion only via Cloud & subscription, so rubbish compared to Sage or Elipsa.

So I created a folder/directory on Laptop for Calibre to send files to as if a device.
