Certainly. This is what I do:
- Set up Syncthing normally (which you have obviously already done)
- Within the folder that you are synchronizing with Syncthing, create a new folder called
joplinor something - In Joplin (on desktop, mobile, and every device), set the synchronization target to your local filesystem.
- Configuration > Synchronization > Synchronization target > File system
- Point it to your
joplinfolder that you created in step 2
- Configuration > Synchronization > Directory to synchronize with (absolute path) >
/your/path/here/joplin
