Hey folks, just setting up syncthing and obsidian for the first time and came across this post. I understand that this person hasn’t asked very well or nicely, but they have probably made an easily fixable mistake which, if we answer it here, we can help other people like me who need to know. Helping the rude person is a side-effect that I can live with. I found the likely answer on reddit: reveddit
And here’s the answer from user Sindar25:
In your Syncthing app, select the folder you share and edit its options. Under ‘ignore patterns’, add “.obsidian” (without the quotes). Repeat these steps for all devices, especially if the folder is as “send&receive”.
Basically, this will tell Syncthing to ignore folder where Obsidian’s plugins and app related session data is being stored. Generally you don’t want to sync this data across different devices, such as PC and phone. The rest of your notes in your Obsidian vault should be synced normally.
If you need to use some plugins on your phone, install them separately on the phone - will save you from a lot of headaches and file conflicts.
