The Nabu Casa Home Assistant Connect ZWA-2 is the ultimate Z-Wave and Z-Wave Long Range USB controller for Home Assistant, engineered for maximum range, reliability, and seamless integration.
Designed by the team behind Home Assistant and Z-Wave JS, the ZWA-2 delivers uncompromising performance for demanding smart home environments. Its precisely tuned, high-gain antenna and robust base maximize Z-Wave signal reach, making it possible to automate detached buildings, penetrate thick construction, and maintain reliable connections across large or challenging properties.
- Peak Z-Wave Performance: The ZWA-2 features a certified 800-series Z-Wave chipset and an omnidirectional antenna with 3.38 dBi peak gain, engineered for optimal wavelength and minimal interference. Z-Wave Long Range support enables responsive communication with distant devices and improved battery life for end devices.
- Plug-and-Play Setup: Enjoy effortless migration from most modern Z-Wave sticks, intuitive start-up wizards, and one-click firmware updates. The ZWA-2 is optimized for Home Assistant, but can also be used with other Z-Wave platforms (with manual setup).
- Dual Network Capability: Run Z-Wave mesh and Z-Wave Long Range networks simultaneously, with full control over which network each device joins. Ideal for both legacy and next-generation Z-Wave devices.
- Interference-Free Operation: Z-Wave operates in its own sub-GHz spectrum, avoiding the congestion of Wi-Fi, Zigbee, and Bluetooth. This allows for superior wall penetration and reliability, even in dense or multi-story homes.
- Professional-Grade Automation: Control thermostats, lighting, security, and sensors across your entire property. Create automation scenes that span multiple buildings, and monitor critical systems in challenging locations.
- Designed for the Home: The ZWA-2’s injection-molded polycarbonate enclosure and sleek lines blend into any décor. The device resembles a candle and lights up like one, with a status LED and an internal accelerometer to ensure optimal placement.
Use Cases
- Detached Buildings: Control garage doors, workshop lighting, and security sensors up to 150+ feet away.
- Property Perimeter: Install smart gates, driveway sensors, and perimeter security at the edge of your property—Z-Wave Long Range reaches up to 1 mile line-of-sight.
- Outdoor Automation: Manage landscape lighting, pool equipment, and irrigation systems from a single hub.
- Challenging Construction: Penetrate thick plaster, brick, or stone walls that block Wi-Fi and Zigbee.
- Multi-Story Homes: Maintain reliable connections from basement to attic without complex repeater networks.
- Basement & Underground: Connect to security systems, utility monitors, and emergency equipment where other wireless signals fail.

About Z-Wave
Z-Wave is a wireless protocol built specifically for smart homes, prioritizing reliability and low-power communication across devices like sensors, locks, switches, and thermostats. It operates on sub-GHz frequencies (commonly around 908–915 MHz in the US), which gives it excellent range and far less interference than crowded 2.4 GHz bands. Its tight device certification process also means Z-Wave products tend to work consistently across brands.
A defining strength of Z-Wave is its mesh network, where each powered device acts as a repeater, passing messages along and strengthening coverage throughout the home. The sub-GHz radio helps signals penetrate walls and floors better than Wi-Fi or Zigbee, making it highly dependable for automation tasks that need to fire every time, like door locks or motion-triggered lights. The network also self-heals, automatically rerouting traffic if a device goes offline.
Z-Wave is designed for low bandwidth but rock-solid communication, making it ideal for routine automation rather than heavy data tasks. It integrates smoothly with platforms like Home Assistant, supports strong encryption for secure devices, and offers features like S2 security for safer pairing. Because devices must pass strict interoperability tests, Z-Wave systems often feel stable and predictable, which is exactly what you want in a smart home that just works.
