KoboSync & Calibre-Web

Is there anyone syncing books on Kobo devices with Calibre-Web?

It did work earlier but now I think, Kobo has blocked it in the latest firmware updates.

I doubt that Kobo would do anything to break the integration. I d suggest validating against the Calibre Web Kobo integration wiki and following the documented problem shooting steps. https://github.com/janeczku/calibre-...bo-Integration

Ok, I'll look into it. So, it works for you? No issues?

It works with Calibre-Web Automated, both: internally and with Tailscale externally. It took a while I got through to it.

Yes, happily using Calibre-Web Automated Next-Gen, link: https://github.com/new-usemame/Calibre-Web-NextGen on a KLC on current firmware using the Kobo Sync API.

Next-gen is the currently maintained fork of Automated, which in turn was a maintenance and feature fork of Calibre-Web (o.g.). I can't recommend it enough, especially as the 'sysadmin' for my family's devices.

I never heard about Nextgen CW before and have tested it shortly. What I've seen is really promising. KoboSync works great.

Only loading the book-covers is a bit slow.

Thank you for sharing.

KoboSync & Calibre-Web

I have a few weeks of experience with NextGen. It’s slightly heavier on the CPU, though it’s only noticeable for me because I use a Raspberry Pi 4 and don’t want to pay the current ram prices.

Concerning KoboSync NextGen is by far the best of all CW-versions I have tested. KoboSync is often a mess, especially if you have to sync more than 1 reader. NextGen doesn't disappoint here. It's reliable and stable as it should be. Really good job!

Currently one has to switch to the CWA-GUI in order to get all available options (e.g. KoboSync-Token). And for the magic bookshelf there is no option to sync with Kobo devices.

I stick with NextGen and looking forward for further improvements.

It's entirely off-topic, but the other quality-of-life service I add into the mix is Rakuyomi for Manga because its streaming, no downloads/conversion or messing with metadata(!).

Kobo sync API and Nickel/kobo for standard books, then tap Koreader via nicklemenu to jump right into manga library. Keeps things nice and tidy.

Nicklemenu > Koreader > Rakuyomi, with a startup plugin to jump right into manga library when Koreader is launched.

Question issues with sync

Hi there,
i am a bit desperate already and i hope you can give me a hint, where i took the wrong turn.

My Setup:
CWNG v4.1.59 in a docker environment with nginx as reverse proxy
Kobo Libra Colour (v4.46.23852)

NGINX config (for the proxy part)
Quote:
location /books/ {
proxy_bind $server_addr;
proxy_pass http://127.0.0.1:8083;
proxy_set_header Host $host;
proxy_set_header X-Script-Name /books;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_buffer_size 1024k;
proxy_buffers 4 512k;
proxy_busy_buffers_size 1024k;
client_max_body_size 50M;
}
docker compose

My Kobo conf
Quote:
[ApplicationPreferences]
SideloadedMode=true

[OneStoreServices]
api_endpoint=https://domain.tld/books/kobo/7fd9f3092e5a8e1bd4b03413129c6fdb
Here's what i did:
1) Enabled Kobo Sync
2) generated a token
3) edited the kobo config (on the Kobo device)
4) rebooted the Kobo
5) tried to sync
Note: the Kobo was working before just fine, nevertheless, i did a full factory reset (via devmode) in order to start from scratch ;-)

Problem:
When trigger a sync ion the Kobo, nothing will be synced.

Here are some findings:
1) when i use the browser (or curl) and browse to the api endpoint (which is also configured on the Kobo device)
Code:
https://domain.tld/books/kobo/7fd9f3092e5a8e1bd4b03413129c6fdb/v1/initialization
I get (among many other lines, of course) the following line back:
Code:
"library_sync":"https://domain.tld/books/kobo/7fd9f3092e5a8e1bd4b03413129c6fdb/v1/library/sync"
2) when i browse (or curl) to the just received sync url, i get a list of books back

--> so, it seems, that everything is working as it should.

BUT:
1) when i use the Kobo with the following config (among others):
Code:
api_endpoint=https://domain.tld/books/kobo/7fd9f3092e5a8e1bd4b03413129c6fdb
I get (among many other lines, of course) the following line back:
Code:
"library_sync":"https://storeapi.kobo.com/v1/library/sync"
(I don't actually get it "back", I can find this part in the docker logs)

--> so, it seems, that the sync "request" is forwarded (if even received by CWNG) to Kobo (i am not logged in and the Kobo is in SideLoadeMode)

So, is there anything i messed up or configured wrong? do you have any idea where the root cause of this problem could be? Any log or anything else i could possibly check?

thank you very much in advance!

Ron

PS: i posted this question also in the discussion area on gh (https://github.com/new-usemame/Calib...scussions/2781), maybe with slightly different keys or ids (tried a few things since yesterday). But either way, the behaviour is the same.
If there will be a solution available on either side (gh or here), I will update the other side respectively.
