So just sync over local wifi basically? I'm pretty sure you can do thing with syncthing if you just disable "global discovery". You can read the local discovery protocol here https://docs.syncthing.net/specs/localdisco-v4.html but afaiu there is no cloud sync involved at that point and just device to device sync.
Perfect, it looks like the thing I want. Hopefully it can do multiple devices in different networks. I'll test it out when I can.
Thank you :)
It's awesome that more people are discovering new useful software through answering here!
No problem! I personally use syncthing to keep my password database synced between my phone, laptop, and desktop. As well as to keep some important files backed up between different devices that way if my hdd or something happens to one of the devices I have backup on the other ones.
Would you be able to trigger it using something like nfc actions, so you'd only have to swipe an nfc tag and it'd start copying automatically? In which case, a few cheap nfc stickers from china, throw them about the house / apt and then carry on with your life.
Probably? I just have it setup to always be running in the background on my devices. So if it detects a file change to my sync folder that gets sent to all other devices currently connected. I use global sync so as long as the device has an internet connection or is on the same local network it should be able to sync.
There is an API to interface with syncthing daemon running on your computer https://docs.syncthing.net/dev/rest.html so if you wrote a program to track the nfc action and interface with that API I think you probably could.
Ah well in that case it wouldn't be needed because as soon as it's in range of the local network would be easier than taking the trouble of using nfc!
