What Is the Power Switch ZEN15 and What Does It Do?
The Power Switch ZEN15 from ZOOZ is a Z-Wave plug-in switch designed for heavy-duty 110V appliances up to 15 amps. It solves the problem of safely controlling and monitoring high-power devices like refrigerators, window AC units, humidifiers, dehumidifiers, fans, sump pumps, or gas clothes dryers in a smart home system. Users commonly connect it to these appliances for remote on/off control, energy monitoring in watts, kWh, amps, and volts, and automation based on schedules or sensors. The device features a 45-degree angled plug for fitting two units in one receptacle, an extra-thick flexible cord, overload protection, and operation in temperatures from 14 to 104 degrees Fahrenheit indoors only. A built-in LED indicates status, signal strength, and energy use, while it acts as a Z-Wave signal repeater.
What Does the Power Switch ZEN15 Work With? (Compatibility and Integrations)
The Power Switch ZEN15 requires a Z-Wave hub for operation and offers direct native integration with certified Z-Wave hubs like Z-Box Hub, Hubitat, HomeSeer, and alarm panels for basic on/off control. Advanced energy monitoring and settings work with open systems such as SmartThings via a custom driver from the Zooz Support Portal, Home Assistant via Z-Wave JS, and others supporting Z-Wave parameters. It uses Z-Wave Plus with AES encryption, S2 security, an 800 Series chip, and Z-Wave Long Range support for extended range, operating locally without cloud dependency once paired. Voice assistant support occurs indirectly through compatible hubs like Hubitat or Home Assistant linking to Alexa or Google Home, but no direct Matter, HomeKit, Wi-Fi, Zigbee, Bluetooth, or Thread support exists. Limitations include no power outage monitoring, hub requirement for all functions, and advanced features needing hub support for parameters like reporting intervals or state recovery after outages.
Does the Power Switch ZEN15 Work With Home Assistant?
Yes, the Power Switch ZEN15 works with Home Assistant using the Z-Wave JS integration. It operates locally for on/off control, energy monitoring, and advanced settings when paired via standard mesh or Z-Wave Long Range with a compatible stick (hardware/firmware 2.0 minimum for Long Range). Typical functionality exposed includes binary switch, power meter, current, voltage, and configuration parameters like overload limits. Inclusion involves putting Z-Wave JS in pairing mode and pressing the action button three times quickly, with SmartStart QR code support in recent versions.
