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 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.

The Zooz 800 Series Z-Wave Long Range Wall Remote & Scene Controller ZEN37 offers versatile functionality with its 4 programmable buttons, allowing users to control up to 24 scenes or devices from a single remote. This feature is ideal for those looking to streamline their smart home setup. The remote is highly flexible in terms of installation, coming with a magnetic base and a screwless wallplate, making it suitable for various locations within the home.

The inclusion of a rechargeable battery ensures ease of maintenance without the need for constant battery replacements. Compatibility is a key strength of this device, as it works with popular hubs like SmartThings, Hubitat, Home Assistant, HomeSeer, and the Z-Box Hub. However, it's essential to verify hub compatibility before purchase, as it may not function with all Z-Wave systems.

The ZEN37 stands out with its long-range capabilities, boasting up to 1300 feet of coverage when paired with a supporting hub, which is excellent for large homes or properties. Security is well addressed with S2 authentication and SmartStart features, ensuring a secure and straightforward pairing process. On the downside, users might find the need for custom drivers with certain hubs a bit cumbersome, particularly for those not as tech-savvy. Those who prioritize ease of use, flexibility, and long-range functionality in their smart home devices will find the Zooz ZEN37 a valuable addition to their setup.
