PRODUCT REVIEW
In-Depth U.S. Market Review
The Honeywell Home RTH9585WF1004 Wi-Fi Smart Color Thermostat is a formidable competitor in the U.S. mid-range smart thermostat market, leveraging the immense brand trust of Honeywell for HVAC products. This model focuses on delivering a robust, color-touchscreen experience with powerful 7-day programming and proven reliability, directly appealing to homeowners who favor a traditional, easy-to-read interface alongside modern Wi-Fi controls. This is an excellent choice for a budget monitor for home use that works with Alexa.
Its niche is the family-oriented or traditional household that wants smart features but prefers a large, intuitive, full-color touchscreen for primary control over a minimalist dial or app-only interface. The gray finish offers a neutral, sophisticated aesthetic that blends well with modern wall paint colors in American homes.
Compared to the "learning" thermostats like Nest, the Honeywell Home RTH9585WF1004 is a highly flexible programmable model, not an automatic one. This means you set the schedule, giving you direct control over your energy usage. The key advantage is its ease of on-device operation and its highly regarded reliability, a hallmark of the Honeywell brand that is deeply trusted by U.S. HVAC professionals.

1. Color Touchscreen and User Experience
The most defining technical feature of the Honeywell Home RTH9585WF1004 is its full-color, intuitive touchscreen. This interface is designed to mimic a familiar smartphone or tablet experience, allowing users to easily navigate menus, set schedules, and view the current temperature with a quick glance. The display color can often be customized to match wall paint or decor, a small but appreciated aesthetic feature in the U.S. home market.
The touch controls allow for immediate, straightforward adjustments, a preference for many users who want to avoid fumbling with an app or relying on a voice assistant for every minor change. This focus on an excellent on-device experience makes it highly accessible to all members of a family.
2. C-Wire Stability and Power Reliability
The reliable performance of the RTH9585WF1004 is directly linked to its C-Wire requirement. Like many mid-to-high-end smart thermostats, it demands a common wire for consistent 24V power. This requirement is a feature, not a bug, ensuring the Wi-Fi radio is always powered and never drains an internal battery.
For the U.S. homeowner, this means fewer headaches with dropped Wi-Fi connections, delayed commands, or a dead screen. It guarantees that the thermostat remains responsive to the mobile app, web portal, and voice commands at all times, leading to greater long-term satisfaction.
3. Voice and App Integration for Smart Control
Despite its strong on-device interface, the thermostat maintains robust smart connectivity, integrating seamlessly with both Alexa and Google Assistant. This dual-ecosystem support is critical for the majority of U.S. smart homes. The Honeywell Home app allows for full remote access, schedule management, and alerts.
You can be halfway to work and check the mobile app to ensure you set the correct 'Away' temperature. The reliable Wi-Fi and C-Wire power make the voice control functions responsive, allowing for quick adjustments from any room with an Echo or Google Home device.
