How to Install

SSH into your reMarkable as root, then run:

wget -O install.sh https://raw.githubusercontent.com/paviro/Syncthing-for-reMarkable/main/install.sh
sh install.sh

The script checks whether Vellum is already installed. If Vellum is missing, it downloads and runs the Vellum bootstrap script, then installs AppLoad with Vellum, starts XOVI/AppLoad, downloads the latest Syncthing for reMarkable release, and installs it to:

/home/root/xovi/exthome/appload/syncthing

The script prompts before making changes. If an older Syncthing app install exists, the script treats the run as an app update: it preserves the installed Syncthing binary and local config.json when present, then replaces the old app files.

Manual Installation

Use these steps if you prefer not to use the install script. First install the AppLoad/XOVI prerequisites, then install Syncthing for reMarkable manually.

Install prerequisites with Vellum

The recommended way to install the AppLoad/XOVI prerequisites is Vellum, the community package manager for reMarkable tablets. Vellum handles package dependencies and device/OS compatibility checks for the packages it installs.

  1. Set up SSH access

    Set up SSH access to your reMarkable if you have not already done so.

  2. Install Vellum

    Follow the Vellum installation instructions on your reMarkable.

  3. Install AppLoad

    Use Vellum to install AppLoad:

    vellum update
vellum add appload

    Read the command output carefully. Vellum may print additional steps depending on your device and OS version.

  4. Rebuild the XOVI hash table

    Rebuild the hash table after installing or updating AppLoad/XOVI packages:

    xovi/rebuild_hashtable

  5. Start XOVI/AppLoad

    Start XOVI after installing AppLoad, and after each reboot if you have not configured an automatic start method:

    xovi/start

Install prerequisites without Vellum

If you cannot use Vellum, you can install the prerequisites manually:

  1. Install XOVI manually

    Install XOVI from https://github.com/asivery/rm-xovi-extensions by using the included installation script.

  2. Install required extensions manually

    Install qt-resource-rebuilder (from the XOVI repo) and rm-appload:

    # Copy the required extensions to the XOVI extensions directory
cp qt-resource-rebuilder.so /home/root/xovi/extensions.d/
cp appload.so /home/root/xovi/extensions.d/

  3. Rebuild the hash table

    xovi/rebuild_hashtable

  4. Start XOVI

    Run XOVI (you must do this every time you reboot your device):

    xovi/start

Install Syncthing for reMarkable

  1. Download Syncthing for reMarkable

    Download the latest release of Syncthing for reMarkable and pick the archive that matches your device:

    • reMarkable Paper Pro / Paper Pro Move → syncthing-rm-appload-aarch64.zip
    • reMarkable 2 → syncthing-rm-appload-armv7.zip (32-bit build, currently untested)

  2. Extract and Copy Files

    Extract the archive and copy the syncthing folder to /home/root/xovi/exthome/appload/ so that it remains as:

    /home/root/xovi/exthome/appload/syncthing

    Note: Most users can ignore the config.sample.json file when using the auto-installer - it's not needed! The auto-installer handles everything automatically. This configuration file is only for advanced users who want to manually manage their Syncthing installation.

  3. Launch Syncthing

    • Open the sidebar on your reMarkable
    • Touch "AppLoad"
    • Launch Syncthing from the AppLoad menu

  4. Closing the App

    To close the app, swipe down from the center top of the screen to display the AppLoad window controls and tap the X button.

Accessing the Syncthing Web Interface

To access Syncthing over your local network (or USB):

  1. Open the Syncthing app on your reMarkable

  2. Tap the Settings button

  3. Enable Network Access

  4. Access the web interface using your device's IP address:

    http://<device-ip>:8384

    Replace <device-ip> with your reMarkable's IP address on your local network.

    or via the USB IP address:

    http://10.11.99.1:8384

⚠️ Security Note: When enabling network access, it's strongly recommended to:

  • Set a password in the Syncthing web interface (Settings → GUI → GUI Authentication)
  • Enable HTTPS in the Syncthing web interface (Settings → GUI → Use HTTPS for GUI)

This ensures your Syncthing instance is protected when accessible over the network.
