Home Assistant Connect ZWA-2 (Z-Wave USB adapter)

The Most Powerful Z-Wave Adapter Available

The ideal way to connect any Z-Wave device to Home Assistant. The antenna and base are precisely tuned to the ideal Z-Wave wavelength, ensuring a reliable connection and maximum range. With support for Z-Wave Long Range*, it offers a more reliable and faster connection to distant devices and improves battery life. Designed by the team behind Home Assistant and Z-Wave JS, it offers simple plug-and-play setup and seamless migration.

*Currently, Z-Wave Long Range only supports North America and Europe, with the availability of compatible devices in Europe still limited.

*This product is not a standalone device. It requires the installation of Home Assistant on a smart home hub (e.g., Home Assistant Green) and compatible Z-Wave end devices.

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

Precisely Engineered

The antenna and base are precisely tuned to the ideal Z-Wave wavelength, ensuring a reliable connection and maximum range.

The Latest Z-WAVE Chipset

The reliable and powerful operation of this device is powered by the certified Z-Wave 800-series chipset, which represents the pinnacle of wireless home automation technology. This chipset provides significantly improved performance and efficiency. Thanks to this, it ensures not only full compatibility with the entire range of existing Z-Wave devices but also support for Z-Wave Long Range (LR) for ultra-long range and optimized power consumption.

Your system will be more stable, more energy-efficient, and future-proof.

Advantages of Z-Wave

Unlike Zigbee, WiFi, and Bluetooth, which share the same radio space, Z-Wave has its own frequency, which better penetrates thick walls and is less susceptible to interference.

Long Range Compatibility

The latest version of the standard provides a more reliable and faster connection to very distant devices and extends battery life.*

*At its launch, Z-Wave Long Range technology had limited device support outside of North America, but this is set to change soon.

 

Developed for Home Assistant

This product was designed and developed directly by the team behind Home Assistant, a globally recognized open-source platform for home automation. Moreover, its integration with Z-Wave JS technology is the work of the same experts, which guarantees seamless compatibility, high reliability, and continuous support.

You get a product that is perfectly tailored for the best user experience within the Home Assistant ecosystem.

Easy Migration

Transitioning from most other adapters to the ZWA-2 can be done in just a few clicks.

Plug & Play

Z-Wave setup has never been easier thanks to our intuitive wizard and one-click firmware updates.

 

More Range, More Possibilities

Now you can easily install a sensor in a mailbox far from the house, or reliably automate a gate at the end of a long driveway. This extends the possibilities of your smart home to the most distant corners of your property.

2nd Generation Platform

At the core of this device is the 2nd generation Home Assistant Connect platform, which is a key upgrade for your smart home. The "2" in the name refers to the newly designed architecture, which focuses on maximizing performance and maintaining openness.

This platform significantly improves the speed of command processing, increases the stability of network communication, and allows for easy integration with a whole range of other devices and protocols.

Designed for the Home

From the injection-molded plastic cover to the elegant lines – designed to blend in with the interior. It resembles a candle – and even glows like one.
