Nightscout	Instructions on how to integrate your Nightscout CGM data into Home Assistant.	Sensor	0.115	Cloud Polling	true	@marciogranzotto	nightscout	platinum	sensor	integration

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

{% include integrations/config_flow.md %}

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.
