@timoschlueter I have a working nightscout with both heroku and azure, but cannot upload values from Libreview using your program. When I try to use this, via heroku it is saying that the free dynos are no longer supported. I would be fine paying for the eco subscription, but I don't see a way to change the web or worker resources. Is it possible to 1.) change the resources for the subscription or 2.) integrate this as a plugin directly with Nightscout? I am so close to making this work and I believe this will be the last step. Thanks in advance.

I have been using this software for a few days to stream Libre 3 data to Nightscout, and it is great. Thank you!

I have noticed a few times that when my son is away from his phone for an extended period (and therefore data is not flowing), that when he returns that this code will fill in some, but not all of the missing data. Both the LibreLink and XDip+ apps seem to fill in all of the missed data. The most items that I have seen this code fill in is 4 ("Upload of 4 measurements to Nightscout"). I am in the USA and using US endpoints.

I am wondering if the /graph API endpoint may need an additional parameter passed to request more data (further back into time) when data has been missed for a while?

Hi Timo,

do you think it is possible to create the Docker container for arm64 in addition to the amd64 platform? Then you could run the whole thing very energy-efficiently on a Raspberry Pi.

Many greets Dirk

Hi Timo,

after the last update from llu on 2022-03-31 the jwt returned by login is rejected in the connections request. I've added a lot of logging to figure out what's going on. Here is the current log file:

Any ideas?

Kind regards Jörg

After setting everything up, this log appears, no data is being uploaded to Nightscout.

Has anybody got an Idea what to do?

2022-08-31T08:10:06.514621+00:00 app[worker.1]: [info]: Upload of 139 measurements to NightScout succeeded

Is it possible to change the port numbers of the nightscout connection ? I have nightscout running locally on a synology nas in docker port 80 and 443 are occupied by the nginx server 1337 is the port i use for web interface is it possible to use other ports to upload the data ? i am new to this so forgive me, as i dont not fully understand everything. my ultimate goal is to obtain the glucose data in home assistant so at night i can make some automations.

Gr.

I have configured an instance of nightscout and this uploader since 2 weeks now. For the first week everything ran fine. The uploader was pushing the current measurement and the backfilled data to nightscout every minute.

After the first week I noticed during one day. that the dots would not appear every minute anymore. The uploader was still logging that it was pushing ~141 Measurements to Nightscout without fail. Nightscout would also not throw any errors but I can only see a dot every five minutes which should just be the backlogged data. Tha nightscout database shows the same.

This porblem was not solved by deleting the docker images of the uploader and nightscout and pulling new ones.

My Graph now looks like this:

I also have a simple ui script using the exact same code thatjust displays the number every minute which is running fine. So my asumption is that nightscout is not correctly saving the data. Do you have any idea if there is a limit of how many uploads a nightscout instance can handle at one time and the uploaded measurements get cut of with only the last few saving?

Many Thanks

Hi, I have the following issue, right after starting the docker-container. It seems to be connected to nightscout and the librelink cloud correctly.

The error might occure because I have no recent blood glucose values in the libre cloud. (But I plan using it in the future, since I have to switch from libre2 to libre3).

[ image deleted as it had sensitive info ] Nightscout upload fails. Just bought a server from https://www.t1pal.com/ and entered upload url and upload secret and it just fails. Any suggestions? Api secret and host value seems to be fine.

Hi,

after setting up Nightscout via Heroku (successfully). I tried to set up libre link up, also via Heroku. But unfortunatily I receive always the following error.

2022-05-01T18:20:00.514429+00:00 app[worker.1]: [info]: no authTicket.expires 2022-05-01T18:20:00.514465+00:00 app[worker.1]: [info]: renew token 2022-05-01T18:20:01.164961+00:00 app[worker.1]: [info]: Logged in to LibreLink Up 2022-05-01T18:20:01.672330+00:00 app[worker.1]: [info]: Found 1 LibreLink Up connection. 2022-05-01T18:20:01.672344+00:00 app[worker.1]: [info]: -> The following connection will be used: XXXXXX (Patient-ID: ) 2022-05-01T18:20:02.254026+00:00 app[worker.1]: [info]: Received blood glucose measurement items 2022-05-01T18:20:02.394919+00:00 app[worker.1]: [error]: Error getting glucose measurements Cannot read properties of undefined (reading 'dateString')

I want to analyze the SHA1 requirement of the Nightscout token. Some users are confused about the hashing of the token. In my instance, I don't hash the token and the plugin still works. Maybe we should update the documentation again. The SHA1 requirement was introduces in PR https://github.com/timoschlueter/nightscout-librelink-up/pull/21. @HansKre since I don't use Heroku: is the hashing something that is necessary on Heroku deployments? It does not seem to be required on local/docker deployments.

hello I am getting the values at 11 minute intervals. I couldn't understand the errors it gave. it gives this error every time a value is loaded..What should I do?

I haven't collected data from libreview for about a month. I redeployed from 1.9.0 to 1.9.1 and it's still the same - AuthFailureError . I assume this happened after updating librelinkup to 4.5.0.

Log from rail.app:

If you compare the delta going up and down ( 5min) its alot higher when you compare with a libre 1 (miaomiao, xdrip4ios) the abbot libre 3 app is compensating down this afterwords a bit in the logged curve,

Is there a way to apply some average filter on the libre 3 bg values before sending it to nightscout

I think they use something like that in Xdrip4ios.

to prevent the curve to overreach actual bg that leads to sharp turns when changing directions

it will also help againt sudden compression drops and even them out a bit

If your looping it will also be easier for loop to regulate a more stable curve and not give to much and then take away basal all the time

It could be an optional feature

If anyone is still looking for Plan B to Heroku, I have been using Azure for a little while now since it is back and both the NightScout website and this wonderful write app from Libre to NightScout works seamlessly.

Follow the same steps as migrating nightscout website from the link below and replace where necessary with librelink-up configurations https://nightscout.github.io/vendors/azure/migrate/

Hello, I notice that the last glucose measure, the value of NOW, don't appear, the postbox glucose measures take 20 minutes of delay. It is right?

Thanks.
