HassAC

HassAC is a community-driven project that aims to provide a smart home automation integration for the Home Assistant platform, specifically designed for controlling air conditioning units. The project focuses on offering broader compatibility with a wider range of air conditioner models and brands than typically found in official integrations. HassAC often achieves this by leveraging common communication protocols or by reverse-engineering existing control methods.

The primary goal of HassAC is to allow users to seamlessly integrate their air conditioners into their Home Assistant ecosystem. This enables centralized control, scheduling, automation, and monitoring of AC units through the Home Assistant interface. Users can typically control functions such as power on/off, temperature adjustments, fan speed, and mode selection (e.g., cool, heat, dry, fan).

Development of HassAC is usually carried out by volunteers within the Home Assistant community. This collaborative approach means that new features, bug fixes, and support for additional AC models are continuously being added. Installation is often managed through Home Assistant's custom integrations or HACS (Home Assistant Community Store), providing a relatively straightforward way for users to add the functionality to their setups. While not an official Home Assistant project, HassAC has gained popularity for its ability to bring otherwise unsupported devices into the smart home fold.
