PRODUCT REVIEW
In-Depth U.S. Market Review
The Honeywell Home RTH9585WF1004 Wi-Fi Smart Color Thermostat is a pillar of the U.S. mid-market for smart home climate control. It successfully combines the reliability and long history of the Honeywell brand with modern necessities: Wi-Fi, a full-color touchscreen, and seamless compatibility with Alexa and Google Assistant. This model is engineered for the homeowner who values a familiar, intuitive, and feature-rich interface—making it an excellent budget-friendly choice for a robust smart thermostat.
The thermostat's central role is to offer highly flexible 7-day programming through a large, customizable color screen. The gray finish is a popular, neutral choice in contemporary U.S. interiors, providing a sleek look without the starkness of white or the high price of designer models. It’s an ideal smart thermostat for home use that requires a direct, tactile control panel.
Compared to minimalist learning thermostats like the Nest, the RTH9585WF1004 is fundamentally a programmable device, meaning you are the one setting the energy-saving schedule. However, it boasts broader compatibility and the undisputed brand recognition of Honeywell, which many U.S. HVAC professionals and consumers trust implicitly. Its C-Wire requirement ensures network stability, a significant benefit over power-stealing competitors.

1. Advanced Touchscreen Technology and Customization
The core technical appeal of the Honeywell Home RTH9585WF1004 is its expansive, high-resolution color touchscreen. This isn't just a basic LCD; it's a dynamic interface where you can easily view system status, outdoor temperature (via Wi-Fi), and energy-saving tips. The ability to customize the background color is a unique aesthetic feature.
This strong on-device interface is particularly valuable for American households where reliance on mobile apps is not universal. It ensures that guests, children, or older adults can easily and intuitively operate the thermostat without needing a smartphone or voice commands.
2. C-Wire and Network Reliability
The mandatory C-Wire connection is a technical decision that firmly places this thermostat in the camp of reliable performers. In the U.S. market, dropped Wi-Fi connections are a leading source of frustration with smart devices. By requiring constant 24V power via the C-Wire, the Honeywell unit maintains a powerful and stable Wi-Fi signal.
This stability is vital for the 7-day scheduling to execute correctly and for the device to respond instantly to Alexa or Google Assistant voice commands. It's a trade-off: a slightly more complicated install for guaranteed long-term, reliable smart performance.
3. Voice Control and Remote Access
The integration with Alexa and Google Assistant is deep and reliable, leveraging Honeywell's cloud services. The remote control is not limited to temperature adjustment; you can also manage the fan and change the heating/cooling mode from your smartphone app from anywhere.
For the user who travels frequently or owns a second home, the mobile app access provides peace of mind and the ability to set the "Vacation" schedule or pre-heat the house before arrival. The Gray color finish is sleek and unobtrusive, fitting seamlessly into most modern décors.
