Hi there and thanks for the post. I have been using both syncthing and nextcloud (similar to owncloud) for different use cases. Nextcloud is running on a RaspberryPi3 (RP3) as a server for uploading and syncing
– photos from phone, PC, Laptop
– documents,
– contacts, calendar etc.
What I have always wanted to achieve is the following:
I want a nextcloud instance running 24/7 as I have done already for the above reasons. But also I want syncthing running on the RP3 and also all computers and phone. Therefore when for example I have a large video on the phone, it will start syncing on the RP3 that is on. When I turn on the first PC it will be “downloading” pieces of the video both from phone and from RP3, . If I turn on also a Laptop then syncing will be completed even faster cause the upload – download process is being handled from several servers (all devices turned on) and not just RP3. This is also very useful if the upload speed of connections are slow. imagine having these seperate devices in several locations.

My question is, have you achieved a setup to your devices as the one I describe above? If yes, could you please upload a short tutorial of how you managed to make owncloud and syncthing work with each other?
