comfort and save energy. The Honeywell Home RTH9585WF1004 Wi-Fi Smart Color Thermostat stands out as a reliable, user-friendly option packed with features designed to make controlling your home’s temperature easier and more efficient. In this review, we’ll explore the key features of this device, compare it to other popular thermostats, discuss its pricing and accessibility, highlight its pros and cons, and finish with some thoughtful conclusions about its value.

Product Features and Technology

The Honeywell RTH9585WF1004 is a 7-day programmable smart thermostat that offers a colorful touch screen display, making it simple to customize your heating and cooling schedules. The touchscreen is vibrant and intuitive, showing current indoor and outdoor temperatures, humidity levels, and system status all at a glance. Unlike some thermostats that rely solely on app control, this Honeywell model provides a rich in-device experience, letting you make adjustments directly on the thermostat without needing to pull out your phone.

Connectivity is seamless thanks to built-in Wi-Fi, allowing remote control via the Honeywell Home app. Whether you’re at work or on vacation, you can monitor and adjust your thermostat from anywhere. The device is also Alexa Ready, meaning it integrates easily with Amazon Alexa for voice control, adding a hands-free convenience factor to your smart home setup.

Additionally, this thermostat carries the Energy Star certification, ensuring it meets energy efficiency standards set by the U.S. Environmental Protection Agency. This means that by using this thermostat properly, you’re likely to see a reduction in your home’s energy consumption and monthly utility bills.

App & Voice Control You’ll Actually Use

Remote control runs through the Total Connect Comfort app, so you can change set points, view status, and adjust schedules away from home. It also works with Alexa and Google Assistant for hands-free changes and basic voice routines. The on-device color touchscreen remains fully usable if you don’t want to reach for your phone.

Compatibility & System Requirements (Read This First)

The RTH9585WF1004 is designed for low-voltage (24-V) HVAC systems—not millivolt fireplaces or 120/240-V baseboard heat—and it typically requires a C-wire for continuous power. If you’re unsure about wiring, Honeywell/Resideo’s C-wire guide explains when you’ll need an adapter or professional wiring.

Comparison with Competitors

When compared with other smart thermostats on the market, the Honeywell RTH9585WF1004 holds its own in several ways. For example, compared to the ecobee Smart Thermostat Premium, Honeywell’s offering lacks some advanced features such as multi-room temperature sensors and indoor air quality monitoring. However, it makes up for this with a more straightforward, colorful touchscreen interface and a solid app experience.

In contrast to the Google Nest Thermostat, which emphasizes sleek design and automatic learning of your routines, the Honeywell model focuses more on manual scheduling and easy programmability. For users who prefer setting precise schedules themselves rather than relying on AI learning, this thermostat is a great fit.

Pricing-wise, the Honeywell RTH9585WF1004 is generally more affordable than premium models like the ecobee Premium or Nest Learning Thermostat, making it a practical choice for budget-conscious buyers who still want smart functionality.

Price and Accessibility

Currently, the Honeywell Home RTH9585WF1004 is priced around $129 USD on popular retail sites like Amazon, which positions it in the mid-range smart thermostat market. This price reflects its solid build quality and feature set without the premium price tag of higher-end competitors.

The device is widely available online and in major home improvement stores across the U.S., ensuring that interested buyers can easily find it and benefit from various sales or promotions. Installation is designed to be user-friendly for most standard HVAC systems, and Honeywell provides detailed guides and customer support to help users get up and running.

Energy Use & Certification

This model is ENERGY STAR® certified and supports 7-day scheduling to cut waste when you’re away or asleep. Many U.S. utilities pair ENERGY STAR thermostats with demand-response programs and occasional rebates, improving real-world savings beyond the purchase price.

Real Advantages and Drawbacks

One of the standout advantages of the Honeywell RTH9585WF1004 is its color touchscreen display. It not only looks modern and appealing on your wall but also makes programming straightforward and visual. The ability to see both indoor and outdoor temperatures, along with humidity, directly on the device is a convenient touch that many users appreciate.

The 7-day programmability allows you to tailor heating and cooling schedules to fit your lifestyle, helping reduce wasted energy during times you’re away or asleep. Plus, the Alexa integration adds a modern smart home convenience, making voice commands an effortless way to adjust temperatures.

On the downside, this thermostat does not include advanced sensors like the ecobee’s smart room sensors, so it cannot manage temperature variations across multiple rooms. Also, it doesn’t have the AI learning features found in Google Nest thermostats, which might disappoint users looking for a more “set it and forget it” experience.

Some users have noted that the touchscreen can occasionally be less responsive than expected, and the overall look is less sleek compared to Nest’s minimalist design. However, for many, these are minor trade-offs for the thermostat’s affordability and reliable performance.
