Custom component for Home Assistant to interact the Carelink platform by Medtronic with integrated Nightscout uploader. The api is mostly the works of @ondrej1024 who made the Python port from another JAVA api.
- Medtronic Guardian Connect CGM (to be confirmed)
- Medtronic MiniMed 770G pump (to be confirmed)
- Medtronic MiniMed 780G pump
HACS is a community store for Home Assistant. You can install HACS and then install Carelink Integration from the HACS store.
Then you can install the integration
Copy the custom_components/carelink to your custom_components folder. Reboot Home Assistant and configure the 'Carelink' integration via the integrations page or press the blue button below.
The needed information for the authentification process can either be provided as file (=logindata.json), or entered during the initial setup of the integration.
The Home Assistant Carelink Integration needs the initial login data stored in the logindata.json file. This file can be created by running the login script on a PC with a screen.
The login script from @ondrej1024's Carelink Python API, written by @palmarci (Pal Marci), was slightly modified and can be found here "carelink_carepartner_api_login.py".
Simply run:
python carelink_carepartner_api_login.py
You might need to install the following Python packages to satisfy the script's dependencies:
- requests
- OpenSSL (pip install pyOpenSSL)
- seleniumwire (pip install selenium-wire)
- curlify (pip install curlify)
For Windows environment the following packages need to be installed too:
setuptools (pip install setuptools)
packaging (pip install packaging)
The script opens a Firefox web browser (so make sure Firefox is installed on your machine) with the Carelink login page. You have to provide your Carelink patients or follower credentials (recommended) and solve the reCapcha. On successful completion of the login, the data file will be created with the following structure:
Either the content of the logindata.json file can be taken over into the setup of the HA Carelink integration, or the entire file can be uploaded into the custom_componend/carelink folder (recommended).
All parameters during setup are optional and a provided file will have a higher priority and overwrite the manual configuration.
If the file was copied to custom_components/carelink before the integration setup was started in Home Assistant, all parameters during the setup can stay empty.
With those information, the Home Assistant Carelink Integration will be able to automatically refresh the login data when it expires.
It should be able to do so within one week of the last refresh.
The scan interval of the integration can be configured during the integration setup. User can configure anything between 30 and 300 seconds. Default is 60 seconds.
To use the Nightscout uploader, it is mandatory to provide the Nightscout URL and the Nightscout API secret.
The Nightscout uploader can upload all SG data and add Treatments with the amount of carbs and insulin.
In order to be able to show the active insulin reported by the pump, the remaining reservoir amount parameter of the nightscout pump plugin has been reused.

- CareLink follower account (with MFA NOT ENABLED)
- Guardian Connect CGM outside US: patient or care partner account
- Guardian Connect CGM inside US: not tested yet! (possibly a care partner account)
- 7xxG pump outside US: care partner account (same as for Medtronic CareLink Connect app)
- 7xxG pump inside US: care partner account (same as for Medtronic CareLink Connect app)
