About the Honeywell Home RTH9585WF Wi-Fi Smart Color Thermostat, Silver
The Honeywell Home Smart Color Thermostat (RTH9585WF) is a Wi-Fi, 7-day programmable thermostat with a color touchscreen. You can choose the display color to suit your space, and adjust temperatures and schedules on the screen itself or from the app when you are away from home.
Scheduling allows four periods per day across all seven days, and Honeywell's Smart Response technology learns your schedule and temperature preferences. The thermostat also keeps an energy usage history, reminds you when the furnace filter needs changing and has a keypad lock. It is ENERGY STAR certified and works with Amazon Alexa for voice control.
It is designed for 24V heating and cooling systems, including heat pumps, and needs a C-wire for power. It mounts on the wall and comes with screws, anchors, wire labels and a quick start guide, making it a fit for homeowners replacing an older programmable thermostat.
What reviewers say

Recurring complaints include the C-wire requirement, occasional app or cloud connection problems, and a feature set that feels dated next to newer smart thermostats.

- Customizable color touchscreen
- Remote control through the app and Alexa
- Helpful filter reminders and energy reports
Cons
- Requires a C-wire
- Some owners report app or cloud connection issues
