Honeywell Home X2S Review
Bottom Line
Choose it for affordable Wi-Fi control, easy installation, clear physical controls, and flexible scheduling. Skip it if you need room sensors, polished voice integrations, detailed energy analytics, quiet relay operation, or seamless auto heat/cool switching.
Best for
Best for shoppers who want an affordable, simple Wi-Fi thermostat with physical buttons, flexible schedules, and dependable phone control. It is especially useful for rentals, vacation homes, garages, and straightforward HVAC setups.
Not for
Skip it if you need room sensors, rich energy analytics, desktop web access, consistently polished voice integrations, or quiet operation near a bedroom. Homes without a C wire may also need extra wiring or an adapter.
Verdict
The Honeywell Home X2S succeeds as a straightforward, budget-friendly smart thermostat. Installation is unusually easy for many owners, the display and physical buttons are clear, scheduling is flexible, and remote control is especially useful for vacations, rentals, garages, and multi-unit buildings. Matter and broad ecosystem support add appeal, but the smart side is less consistent than the core thermostat: Alexa, Home Assistant, Hubitat, older Honeywell integrations, and some Wi-Fi setups draw complaints. A C wire is commonly required, room sensors are unsupported, energy reports are basic, and several owners dislike loud relay clicks or missing auto heat/cool behavior. For buyers who value simple control over premium automation, the overall value is strong.

Pros
-
Installation is one of the X2S’s biggest strengths, with many owners calling the swap unusually easy and fast. More complex wiring or heat-pump configurations can still require extra work or professional help.
-
Remote temperature monitoring and adjustment are among the most consistently praised features, especially for vacations, garages, churches, and rentals. A few third-party or network-specific setups caused inaccurate or unavailable remote control.
-
Most short-form owner impressions are strongly positive, describing the thermostat as simple, convenient, and effective. A smaller group encountered enough problems to abandon it or recommend against it.
-
Value is one of the strongest themes: many owners see the X2S as an affordable way to get reliable Wi-Fi control, scheduling, and broad compatibility. The value falls apart for buyers who hit hardware, wiring, or sensor limitations.
-
Physical buttons are a major usability strength for people who prefer straightforward controls over touchscreens. Most find them simple, though deeper menu navigation can become tedious.
-
The monochrome display is widely praised for clear, easy-to-read temperature information, especially when lit. The main caveat is that some secondary text can look small to older eyes.
Cons
-
Automatic heat/cool switching is a repeated frustration. Several owners say they cannot set the temperature bracket they expect from a smart thermostat, or find switching behavior unreliable.
-
The relay click is a recurring complaint and can be very loud when heating or cooling switches on or off. It may be especially distracting in a bedroom or other quiet space.
-
Outage recovery is a weak point in the limited reports available. One failed unit would not return after a power cycle, while another lost time and scheduling after power failure.
-
Voice control is one of the shakier smart features. Siri missed the requested temperature for one reviewer, while multiple owners reported Alexa commands unavailable despite advertised compatibility.
-
Energy reporting is basic and often disappointing for shoppers who want detailed analytics. One rental owner likes the daily boiler-runtime report, but others criticize delayed, incomplete, or inaccurate run-time metrics.
-
Temperature accuracy is inconsistent across the reports. One multi-unit installation found the thermostats accurate, but other owners saw schedule errors or readings two to five degrees high.

FAQ
Does the Honeywell Home X2S require a C wire?
Plan on a C wire for normal smart operation. Several owners needed new wiring or an adapter, although one reported the thermostat could run without C while sacrificing an always-on backlight.
Is the X2S easy to install?
Usually yes. Many owners call installation unusually easy, especially with an existing Honeywell UWP wall plate, but heat-pump wiring and missing C wires can add complexity.
Is the First Alert app good?
Experiences are mixed. Many owners find it simple and reliable, while others dislike the app naming, setup flow, limited analytics, or migration from older Honeywell apps.
How well do Alexa, Apple Home, and Google Home work?
Apple Home and Google support are generally workable, but Apple controls can be basic. Alexa is more inconsistent, with multiple owners reporting linking or voice-control failures.
Does the X2S support remote room sensors?
No. Several sources specifically note that the X2S does not work with Honeywell remote room sensors, a tradeoff some owners accept for the lower price.
Are the energy reports detailed?
No. The app can show HVAC runtime and one rental owner found that useful, but other owners criticize the reports as delayed, incomplete, or inaccurate.
