Honeywell RTH9585WF1004 Smart Color Thermostat Review
Quick Verdict
Best for: Homeowners with a compatible HVAC system and a C‑wire who want a Wi‑Fi, Alexa‑ready thermostat with a color touchscreen and Energy Star benefits.
Watch out: Requires a C‑wire; not compatible with electric baseboard heat (120–240V). Listing omits app details, warranty, and broader smart home integrations.
Bottom line: A practical, Energy Star‑rated Wi‑Fi thermostat at a reasonable price if your system is compatible — confirm app and warranty details before buying.
Buy this if: Homeowners with a standard forced‑air, hot water/steam, or heat pump system who have (or can add) a C‑wire, want Energy Star‑rated efficiency tracking, and prefer a touchscreen thermostat that works with Alexa.
Skip this if: Residents using electric baseboard heating (120–240V), buyers without a C‑wire who don’t want to install one, or anyone needing detailed app, warranty, or advanced smart‑home integrations not specified in the listing.
