ZEN51 Relay vs ZEN30 Fan Switch
Device Function
The Zooz ZEN51 is a smart relay designed for on/off control. It installs behind an existing wall switch or at the light fixture. This allows you to keep your preferred switch style while adding Z-Wave automation. The Zooz ZEN30 is a double switch with a dimmer. It controls lights independently with smooth brightness adjustment for incandescent and LED bulbs. It also includes a relay button to turn connected ceiling or exhaust fans on or off. Note that the ZEN30 does not provide speed control for the fan, only basic on/off functionality.
Connectivity Standard
Both devices utilize Z-Wave Long Range technology to extend your network coverage. The Zooz ZEN51 operates on the 700 Series Z-Wave platform. It supports S2 authenticated security and SmartStart for easy pairing. The Zooz ZEN30 uses the newer 800 Series Z-Wave Long Range. This generation offers faster signal speeds and greater range than previous iterations. The ZEN30 also acts as a signal extender in a traditional mesh network if your hub does not yet support Long Range. Both require a compatible hub to display their advanced features correctly.
3-Way Compatibility
Wiring flexibility varies between these two models. The Zooz ZEN51 supports true 3-way setups. You can automate 3-way configurations even if neutral wire is not available at the switch box, by installing the relay at the light fixture where power and neutral are present. The Zooz ZEN30 does not support direct 3-way wiring. It only offers virtual 3-way functionality through your hub software. If you have existing mechanical 3-way switches and want hardware-level coordination, the ZEN51 provides a more straightforward integration path without relying on software emulation.
Size and Fit
Installation space is a key factor in crowded electrical boxes. The Zooz ZEN51 is a compact relay measuring 1.5 inches by 1.4 inches with a depth of 0.7 inches. Its small form factor allows it to fit in the tightest spaces. The Zooz ZEN30 is a double switch unit measuring 1.7 inches by 4.1 inches with a depth of 1.1 inches. While it is designed to fit shallow boxes, it is physically larger than the relay. If you are replacing a single switch in a very deep or crowded box, the ZEN51 offers more room for wire management.
Hub Compatibility
Both devices require an open Z-Wave hub and work best with the Z-Box Hub. The Zooz ZEN51 is tested to work well with Hubitat, Home Assistant, HomeSeer, and SmartThings. It offers straightforward compatibility across major platforms. The Zooz ZEN30 works with Home Assistant and Hubitat. For SmartThings, it requires a custom device driver, and you must contact support for details. It is explicitly not supported by Vivint, ADT Pulse, Ring, or Alarm.com. If you use SmartThings without custom coding, the ZEN51 provides a smoother setup experience.
Which ZOOZ switch fits your needs
You need independent fan and light control
The ZEN30 features a dual switch design. You can dim lights up to 75 watts using the paddle. The separate relay button controls a fan on or off. It does not offer fan speed control. This model handles two distinct loads in one unit, making it ideal for ceiling fan and light combos.
You want to keep your existing switch
The ZEN51 is a compact relay that installs behind your current wall switch. It measures just 1.5 by 1.4 inches. You retain your favorite switch style and color. The device adds Z-Wave Long Range automation to a standard mechanical switch. It is perfect for users who prefer the look of traditional switches.
You need true 3-way wiring support
The ZEN51 supports physical 3-way setups natively. You can wire it for standard multi-location control. The ZEN30 only offers virtual 3-way functionality. If you have existing 3-way switches and want reliable automation without complex virtual setups, the ZEN51 provides a more straightforward hardware solution for your lighting circuit.

Frequently asked questions
Does the ZOOZ ZEN51 relay support dimming?
No, the ZOOZ ZEN51 is an on/off smart relay. It provides basic switching control rather than variable light output. You should choose this model only if you need simple automation for lights that do not require dimming capabilities. It is designed for users who want to keep their existing switch style while adding Z-Wave functionality.
Can I control a ceiling fan with the ZOOZ ZEN30?
Yes, the ZOOZ ZEN30 includes a separate relay button for fan control. This button turns the fan on or off. It does not offer speed adjustment or variable speed control. You can use the paddle to dim the lights independently while the fan runs at a fixed speed set by its own wall control.
Do these ZOOZ switches work without a hub?
No, both devices require a Z-Wave hub to function. You cannot connect them directly to your phone or router. The hub acts as the central brain for your network. You need a compatible hub like SmartThings or Home Assistant to automate these switches and control them remotely.
What is the difference between Z-Wave Long Range and standard Z-Wave?
Z-Wave Long Range offers extended range and better wall penetration compared to standard Z-Wave. The ZEN30 features 800LR connectivity for stronger signals. This technology helps maintain reliable connections in larger homes or areas with more obstacles. It ensures your commands reach the device even from a distance.
Is the ZOOZ ZEN51 a dimmer or a switch?
The ZOOZ ZEN51 is a smart relay switch, not a dimmer. It provides on/off control for connected loads. It fits behind existing wall switches or at light fixtures. This allows you to automate standard switches without replacing them. It is ideal for users who prefer the look of traditional switches.
Can I use the ZEN30 for a ceiling fan with light?
Yes, the ZEN30 is designed for ceiling fan and light combinations. It features a dual switch design for independent control. You can dim the lights up to 75 watts using the paddle. The separate relay button handles the fan power. This setup allows you to manage both components separately from your automation system.
Do I need a neutral wire for these ZOOZ devices?
Yes, both the ZEN51 and ZEN30 require a neutral wire for installation. They cannot operate on power alone. You must have a neutral wire available in your switch box. This is a standard requirement for most modern smart switches. Check your existing wiring before purchasing to ensure compatibility.
Which ZOOZ model is better for independent light control?
The ZEN30 is better for independent light control. It includes a dedicated paddle for dimming lights up to 75 watts. You can adjust brightness precisely while controlling the fan separately. The ZEN51 only offers on/off switching. Choose the ZEN30 if you want fine-tuned lighting adjustments alongside your automation routine.
