The most powerful way to connect Z-Wave devices to Home Assistant

The Home Assistant Connect ZWA-2 is currently the most capable Z-Wave adapter for Home Assistant. It was developed from the ground up to ensure maximum range and reliability when connecting to Z-Wave devices – featuring the latest 800 series chipset.

Thanks to a precisely tuned antenna, matched to Z-Wave’s ideal wavelength, it offers highly stable connections and extended range. Support for Z-Wave Long Range* (currently available in the EU and US) enables even greater wireless reach while reducing power consumption.

The ZWA-2 was developed by the team behind Home Assistant and Z-Wave JS and integrates seamlessly with your smart home system. Setup is fast and easy – including an intuitive setup wizard and automatic firmware updates.
