10 Best Z Wave Controllers 2025 in the United States

The Honeywell TH6320ZW2003 T6 Pro Series Z-Wave Stat Thermostat is a solid choice for anyone looking to integrate smart temperature control into their home. Its compatibility with popular Z-Wave controllers like Vera and SmartThings ensures that it can fit seamlessly into a variety of smart home setups. This thermostat learns your heating and cooling cycles, making it efficient in maintaining desired temperatures while potentially saving you on energy costs.

Ease of use is a standout feature with its touch screen display and intuitive controls. This makes it accessible even for users who may not be very tech-savvy. The app control method adds flexibility, allowing for remote adjustments from your smartphone, which is a great convenience.

On the automation front, the thermostat offers good capabilities, enabling users to set custom schedules and temperature preferences. It might not have as many advanced features as some higher-end models, which could limit its appeal to those looking for more complex smart home scenarios. One potential drawback is its reliance on batteries (3 AA batteries required), which might necessitate periodic replacements. Additionally, the power source and battery reliance might pose an inconvenience compared to hardwired alternatives. Its size and design are fairly standard, so while it fits well in most spaces, it may not stand out aesthetically.

The UltraPro Z-Wave Smart Light Dimmer offers several standout features that make it a strong contender for home automation. It is compatible with popular voice assistants like Google Assistant and Amazon Alexa, adding convenience for users who want voice control over their lighting. The dimmer also boasts QuickFit and SimpleWire technologies, which simplify installation. QuickFit reduces the housing depth, making it suitable for older switch boxes and confined spaces, while SimpleWire auto-detects wires for faster setup. These features contribute to ease of use, especially for those who may not be technically inclined.

The dimmer is also 3-way ready, meaning it can be used in multi-switch configurations, which adds versatility to its automation capabilities. Additional benefits include its function as a repeater and range extender, helping to strengthen the Z-Wave network in your home. Security-wise, the dimmer supports Z-Wave, which is known for its secure communication protocols, though specific security features are not detailed.

One possible drawback is that a Z-Wave hub is required for operation, which could lead to additional costs if you don't already own one. Furthermore, while the product aims to reduce light flickering, achieving optimal performance might require an additional purchase of the Direct Lighting Bypass (ASIN: B08ZJQV7W2). This means there could be added expenses for achieving the best performance. To sum up, the UltraPro Z-Wave Smart Light Dimmer is user-friendly, versatile, and enhances home automation, but be mindful of the need for a Z-Wave hub and potential extra costs for optimal functionality.

The Zooz 700 Series Z-Wave Long Range Double Relay ZEN52 is a versatile device that allows you to control two lights independently. It is designed to work seamlessly with SmartThings, Hubitat, and Home Assistant (JS), making it compatible with popular home automation systems. You will need a Z-Wave hub, which is sold separately, to use this device. Installation is straightforward, thanks to the pigtail wires and compact size, but it requires a neutral wire, so make sure to check your wiring before purchasing.

One of its standout features is its ability to work with 3-way switches, which is not commonly found in other smart relays. This means you can retain your preferred wall switch style even in multiway setups. The relay also supports smart bulb mode, allowing you to control smart bulbs without cutting power to them when off. This is ideal for those who have already invested in smart lighting. In terms of security, the ZEN52 supports S2 authenticated security, providing an additional layer of protection for your home automation system.

The device also benefits from the Z-Wave 700 series features, including long-range capabilities and SmartStart for easier setup. However, this advanced functionality requires an updated Z-Wave hub that supports these features. The relay is easy to install and offers extensive compatibility with various hubs but has some limitations. It cannot be connected to dimmers or other electronic switches and is intended for simple on/off or momentary mechanical switches only. Additionally, it comes with a 1.5 Amp current rating, which may not be sufficient for higher load applications. With US-based support available seven days a week and a five-year warranty upon registration, the Zooz ZEN52 provides good after-sales service, enhancing its reliability. This makes it a strong contender for anyone looking to add smart control to their existing lighting setup without replacing their current switches.
