Honeywell Total Connect Comfort (Europe) for Home Assistant (built-in integration)

About

Honeywell Total Connect Comfort (Europe) is a built-in integration for Honeywell heating systems that use the vendor's cloud. It adds climate, water heater and button entities to Home Assistant. Actions let a zone setpoint or a hot water state be overridden, either indefinitely or for a set duration, after which the schedule resumes. Another action sets the system mode, indefinitely or until an end time, after which it reverts to Auto, though not every system supports every mode. Older actions for clearing zone overrides, refreshing the system and resetting the system are deprecated, and repair notices can appear in Settings under Repairs. Setup is done in the configuration file.
