The Dexcom integration allows you to view your CGM data from Dexcom in Home Assistant.
You will need to set up the Dexcom Share feature in your Dexcom G6 App to use this integration. Enabling the Dexcom Share service requires setup of at least one follower. The integration will use the Dexcom user’s credentials, not the follower’s credentials.

There are two Dexcom Share servers,
US for United States customers, and

If you have a sensor session running, and once you have enabled the Dexcom integration, you should see the following sensors:
