The Home Assistant Connect ZWA-2 makes smart home automation possible in challenging scenarios where other systems fail.

Reach Beyond Your Walls

Detached Buildings

Control garage doors, workshop lighting, and security sensors in detached garages, sheds, or pool houses up to 150+ feet away. No more dead zones or unreliable connections.

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

Control landscape lighting, pool equipment, and irrigation systems across your entire property from a single hub.

Conquer Challenging Construction

Historic Homes

Penetrate thick plaster walls, brick, and stone construction that blocks WiFi and Zigbee. Z-Wave's 900MHz frequency cuts through materials that stop other protocols.

Multi-Story Homes

Maintain reliable connections from basement to third floor without complex repeater networks. Works through concrete floors and metal construction.

Interference-Free Operation

Operate in busy WiFi environments without dropouts. Z-Wave has its own frequency band, avoiding congestion from neighbors' networks and devices.

Comprehensive Security & Monitoring

Whole-Property Security

Monitor doors, windows, and motion sensors across multiple buildings with reliable, always-on connectivity.

Critical System Monitoring

Place leak sensors, temperature monitors, and equipment sensors anywhere on your property. Get instant alerts for sump pumps, water heaters, and HVAC systems in remote locations.

Basement & Underground Reliability

Maintain connections to basement security systems, utility monitors, and emergency equipment where other wireless signals fail.

Professional-Grade Automation

Energy Management

Control thermostats, lighting, and equipment in remote zones and outbuildings. Optimize energy usage across your entire property.

Unified Control

Create automation scenes that span multiple buildings. "Away mode" secures all structures, adjusts all thermostats, and monitors all entry points simultaneously.

Future-Ready

Z-Wave Long Range support ensures compatibility with next-generation devices offering even greater range and battery life.

The ZWA-2's superior range, wall penetration, and interference resistance solve real problems that limit other smart home systems. Your automation grows to match your property, not your technology's limitations.
