Home Assistant Connect ZWA-2 Adapter - Z-Wave 800 - Long Range - Plus - Plus V2

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

The Home Assistant Connect ZWA-2 is currently the most powerful Z-Wave adapter for Home Assistant. It has been designed from the ground up to ensure maximum range and reliability when connecting to Z-Wave devices – with support for the latest 800 series chipset.

Thanks to a specially tuned antenna that is precisely designed for the ideal Z-Wave wavelength, it offers a particularly stable connection and high range. Support for Z-Wave Long Range* (currently for EU and US) allows for even greater radio range while simultaneously reducing power consumption.

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

Note: The Connect ZWA-2 was designed for use with Home Assistant and the Z-Wave JS add-on. If you want to use it without Home Assistant, please visit: https://go.nabucasa.com/zwa-2-without-home-assistant

Note on Z-Wave Long Range: Z-Wave Long Range is currently only supported in the EU and US regions. The availability of compatible devices in Europe is currently still limited but is continuously expanding.
