# Ouman EH-800

> Ouman EH-800 is a built-in integration for Home Assistant. It has 22 installs sharing analytics and works locally.

Ouman EH-800 is a built-in integration that connects Home Assistant to the Ouman EH-800 heating controller. It talks to the controller locally through the address of its web interface, using the username and password for that interface. It adds a climate entity along with sensors for outdoor temperature, room temperature, supply water temperature and valve position. Number entities cover the heating curve temperatures, the temperature drop settings, the room temperature fine tuning and the minimum and maximum water out temperatures. Selects handle home or away mode, operation mode, relay control and pump summer stop, and a valve entity sets the valve position setpoint. Setup is done in the UI, and the connection settings can be changed later without removing the integration.
