A guide for setting up Syncthing on a reMarkable.

0. Install syncthing on the host machine and get the computer's id. You must also have Toltec or Entware installed on the reMarkable.

1. Install syncthing on the reMarkable and start up the configuration GUI.

opkg install syncthing
syncthing -gui-address "https://0.0.0.0:8888" -no-restart

2. Browse to the reMarkable Syncthing interface at https://10.11.99.1:8888

3. Add folders to sync. I chose /home/root/books for syncing documents to Plato. /usr/share/remarkable/ and /home/root/.local/share/remarkable/xochitl/ may also be of interest.

4. Add a remote device (your computer). Syncthing may automatically detect your computer's id. Under the Sharing tab, enable Auto Accept and check the folder you previously created.

5. Browse to https://localhost:8080 and wait for a prompt to connect to the reMarkable and accept. This took about 30s to appear.

6. Wait for another prompt to receive the shared folder and accept. Verify that folder syncing works.

7. Copy syncthing.service to /etc/systemd/system/ then start and enable the service

wget https://raw.githubusercontent.com/Evidlo/remarkable_syncthing/master/syncthing.service -O /etc/systemd/system/syncthing.service
systemctl daemon-reload
systemctl start syncthing
systemctl enable syncthing

• At least one of the devices must be publically accessible on TCP 22000. Alternatively, if at least one of the devices can access the other on local intranet, you can add another discovery method via [Remote Device] > Edit > Advanced > Addresses.. eg: tcp://192.168.1.123:22000

• WiFi needs to be on an connected for this to work, so xochitl should be running.
