# Dexcom

> Dexcom is a built-in integration for Home Assistant. It has 907 installs sharing analytics and needs the vendor's cloud.

Dexcom is a built-in integration that brings Dexcom glucose monitoring data into Home Assistant. It adds sensors for the current glucose value and the glucose trend. Data comes from the vendor's cloud, so an internet connection is required. Setup happens in the UI, where a username, password and server are entered. An option lets the unit of measurement be changed. Nothing extra needs to be installed, since it ships with Home Assistant.
