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.
Adding Dexcom to your Home Assistant instance can be done via the user interface, by using this My button:
If the above My button doesn’t work, you can also perform the following steps manually:
Browse to your Home Assistant instance.
In the sidebar click on Settings.
From the configuration menu select: Devices & Services.
In the bottom right, click on the Add Integration button.
From the list, search and select “Dexcom”.
Follow the instruction on screen to complete the set up.
There are two Dexcom Share servers,
US for United States customers, and
OUS for all customers outside of the United States.
