The Nightscout integration allows you to view your CGM data from Nightscout in Home Assistant.

Configuration

To add Nightscout to your installation, go to Configuration >> Integrations in the UI, click the button with + sign and from the list of integrations select Nightscout.

Then input your server address in the URL field. For example:

• https://localhost:5423
• https://your-app-name.herokuapp.com

If your Nightscout instance requires authentication for API access, you are also required to input the API Key in the configuration form.

Sensor

If you have a sensor session running, and you have enabled the Nightscout integration, you should see a sensor.blood_glucose entity.

The icon changes to indicate the direction or trend, of the glucose readings. The state is the last reading from Nightscout, and you can see other information about the reading in the sensor's attributes.
