Integration stopped working since yesterday

[Pleister023]

Hi, Happy user here. But, since yesterday the integration stopped working. I think either a) something changed on their side, or b) my credentials in HA are expired (how to change??) or c) the integration does not play nice with HA Core 2025.10.1 a/o OS 16.2. This is what the logs reveal:

Error setting up entry ****** (via @.nl) for librelink Traceback (most recent call last): File "/config/custom_components/librelink/api.py", line 187, in _call_api response.raise_for_status() ~~~~~~~~~~~~~~~~~~~~~~~~~^^ File "/usr/local/lib/python3.13/site-packages/aiohttp/client_reqrep.py", line 629, in raise_for_status raise ClientResponseError( ...<5 lines>... ) aiohttp.client_exceptions.ClientResponseError: 430, message='', url='https://api-eu.libreview.io/llu/auth/login'

The above exception was the direct cause of the following exception:

Suggestions anyone?

Thanks, Remco.

The same thing happened to me. I tried logging in from Postman, and it seems to require new headers.

Same problem (I think):

Mine went offline/disconnected Oct 8th around 1PM central time

[balajeek]

Mine broke too, i tried delete and create again and it fails to add now. not sure where the fault is.

[mijnham]

Might have something to do with the email warning they keep broadcasting via email?

"Starting October 8, 2025, LibreLinkUp app versions prior to 4.16 will no longer receive glucose data from your connected devices. Your app version will then no longer be supported. To continue receiving glucose data, update to version 4.16 of the app today."

[jterfehr2000]

I have 4.16 and the problem persists. I didn't bt think it's that.

[jamied90]

same here 430 error since 7:05 pm gmt yesterday i posted on the Home Assistant Discord also, but no replies as far

[criterion67]

Same issue for me in HA since yesterday (10/08/25).

• Installation method: HAOS
• Core: 2025.10.1
• Supervisor: 2025.10.0
• Operating System: 16.2
• Frontend: 20251001.0

I also use the GlucoDataHandler app (not in HA) and it also pulls data from librelinkup for displaying as a phone widget and on my Samsung Galaxy Watch 7. It's still working with no issues, so it's not likely on Abbotts side.

I sure hope this gets fixed quickly as I rely on it heavily.

Many thanks to the dev on this project! 🙏

[gjgeary]

I found that others with 3rd party apps were having issues since yesterday. I found this on a redit. https://www.reddit.com/r/Freestylelibre/comments/1o1j5gq/comment/niksa3s/?force-legacy-sct=1

Here is a comment that I found that might be of some use.

Yea, figured it. Im so happy about that.

LibreLink/LibreView API broke after the Oct 2025 update

Abbott changed the LinkUp (LLU) API used by apps like LibreView.

Old scripts started failing with 403 Forbidden or 400 RequiredHeaderMissing.

What changed

New required HTTP header:

Account-Id = SHA-256 hash of your user.id (returned from /llu/auth/login)

Old version headers (< 4.16.0) are now

How to fix

Update request headers:

product: llu.android

version: 4.16.0

2. After login, compute:

account_id = hashlib.sha256(user_id.encode()).hexdigest()

and include it in all requests as

Account-Id: <that_hash>.

Keep Authorization: Bearer as before.

Once added, /llu/connections and /llu/connections/{id}/graph work again.

[jamied90]

i have emailed Giles directly, but i have just come across his latest update in the readme, which states "# Not maintained because a lack of access to a Librelink sensor" so it doesn't look good for the future of this integration but this integration has litrally saved the life of my partner when his glucose dropped to dangerous levels but due to the automations i have set up with it as im a heavy sleeper and i just sleep through the notifications from the librelink app i have the house wake me up with lights and alexa notifications so i can deal with his glucose

I have no idea how to code, but if anyone knows of another solution, please let me know

[peggleg]

Mine also stopped working... Tried updating the VERSION_APP from 4.7 to 4.16.0 in the const.py file for librelink, but still getting the below after a HA machine reboot

Try updating with the PR that has been pending since April, with the VERSION_APP updated to 4.16.0 as well

HASH Table PR

this will be my try as well later today

Amazing, thank you very much. I removed the old integration, added this repo and installed. Before restarting HA, I updated the version to 4.16. Restarted HA and added my credentails using Global server and my reading is back in HA. I did obviously lose my historic data

I am so glad! Takes a community sometimes! What I love about opensource projects!

[jhthorsen]

I just changed to https://github.com/dodog/librelink, which works! Thanks @dodog!

[awtx-jeffjohnson]

Switching to https://github.com/dodog/librelink worked for me. Thanks

[criterion67]

Woo hoo .. I finally got it working again!

I had to completely remove the old integration using the File Editor* as every time I would try to redownload, it would keep reverting to the old gilesvs version.

BACK UP HOME ASSISTANT BEFORE PROCEEDING

1. Go to File Editor: honeassistant/custom_components/librelink and delete each of the subfolders 1 by 1 until everything is gone.
2. Next, go to Developer Tools/Check Configuration, to make sure everything is okay. You'll see "Configuration will not prevent Home Assistant from starting!" if everything's okay.
3. Restart HA
4. Add the new custom repository link (https://github.com/dodog/librelink) via HACS.

One thing to note is that mine displayed two version options in HACS. I downloaded the one that showed "updated 2 days ago".

5. Check via the File Editor to make sure that it shows the 4.16.0 version
6. Restart Home Assistant once again
7. Add it through Settings/Devices & Services/Integrations
8. Log in with your LibreLinkUp credentials and everything should be back to normal again!

Sorry for the long post, but I wanted to try to be detailed in the steps that I took, in case it may help someone else.

Very thankful for this community! 🙏

Oh! Finally, this is awesome, I did the same and got it working now. Thank you so much.

Criterion67's instructions (with a little trial and error) worked for me! I am back up and running.

Glad it's back up and running for you! 👍

[realcodfish]

There seem to be two versions around, the latest being a dodog fork from gillesvs, which is confusing. However, for me at least, the dodog fork issues an error when the integration is enabled (Unknown error has occurred). TL;DR both are broken for me.

[dodog]

@realcodfish I just changed the version as I wrote in comment to make it compatible with latest librelink. But not everybody was able to do it, so I made a fork and published it to maintain the history of measured data. The original author is gillesvs, but he does not maintain his repository. Some major updates were done by @kubasaw fork.

What version were you using? Can you check the logs in HA what exactly is the reason for your error?

[realcodfish]

@dodog It may have been my issue...apologies for that. I was authenticating with 'Europe' but it seems only to work with 'Global' for me. Up and running, thank you!.

[dodog]

@realcodfish, I'm glad that's been resolved.

[timswfsby]

I've followed the steps to remove gillesvs's version - including file manasger - but when I add the @dodog one HACS still shows gillesvs's. Thank you for your hard work on this.

[dodog]

@timswfsby Yes, because the author is gillesvs. I can't take credit for his code. Just check, if the version of Librelink integration in HACS shows v1.2.4. If yes, everything is ok.

[timswfsby]

Perfect thank you all working again now

[Stu333]

Criterion67's instructions work! Back up and running. Awesome work, where is the right @dodog Buy me a Coffee link? 👏
