# Viessmann ViCare

> Viessmann ViCare is a built-in integration for Home Assistant. It has 6.5k installs sharing analytics and needs the vendor's cloud.

Viessmann ViCare is a built-in integration that connects Viessmann heating systems to Home Assistant through the vendor's cloud. It adds climate control for heating, a domestic hot water heater, a ventilation fan, and a select for the hot water operating mode. Number entities cover comfort and normal temperatures, hot water temperature settings, hysteresis values, and the heating curve shift and slope. Binary sensors report states such as burner, compressor, pumps and frost protection, while a large set of sensors reads temperatures and burner data. Buttons start or stop a one-time hot water charge, and switches handle modes like Eco, Boost and Silent. Setup happens in the UI with the vendor's sign-in page, and a separate action sets the ViCare mode of the climate device.
