# Danfoss Ally

> Danfoss Ally is a Marketplace integration for Home Assistant. It has 430 installs sharing analytics, needs the vendor's cloud and was last updated October 27, 2026.

Danfoss Ally is an integration that connects Danfoss Ally and Icon thermostats to Home Assistant through the Danfoss Ally gateway. It relies on the vendor's cloud and is set up in the UI with a Consumer Key and Consumer Secret from a Danfoss developer account. It adds a thermostat climate entity with sensors for temperature, battery, humidity, floor temperature and valve opening. Switches cover open window detection, pre-heat, load balance and radiator covered, while numbers set temperatures for preset modes such as at home, leaving home and pause. Radiator thermostats can use an external temperature sensor chosen in the thermostat configuration, and an open window reduces heating. A diagnostics download is available for bug reports.
