Humidity quietly shapes how a room feels long before you touch the temperature dial. Dry winter air pulls moisture from your sinuses, while a damp summer afternoon makes 72°F feel sticky, so a thermostat that only watches temperature misses half the picture. Smart thermostats with humidity control track both readings and respond in ways a basic programmable unit never could.
These nine picks cover a wide spread of homes, heating systems, and budgets. Some lean toward learning algorithms and automation, others toward raw compatibility with electric baseboards or whole-home security platforms. The right match depends on your HVAC setup, the size of the rooms you want to monitor, and how much you’d like the system to think on its behalf.

More On The Choices That Made The List
Emerson’s Sensi Touch 2 takes a different approach than the entry-level Nest above. The full-color display reads clearly across the room, and the companion app handles setup with a guided sequence that walks you through wiring one step at a time. A common wire (c-wire) is required, which is the thin dedicated power line that keeps the Wi-Fi radio alive without draining the heating circuit. Most newer homes already have one, but older systems may need a quick adapter.
Where this unit earns its keep is balance. It plays nicely with the Sensi Room Sensors (sold separately), letting you average readings from multiple rooms so the upstairs bedroom doesn’t roast while the downstairs stays cool. Compared to the Honeywell RTH9585WF reviewed later, the Sensi leans more on scheduling and less on visual customization, which suits shoppers who want predictable behavior over flashy aesthetics.
The Practical Payoff
- Compatible with separate Sensi Room Sensors to even out hot and cold spots across the home.
- ENERGY STAR certification, which is the federal efficiency label that signals lower standby power draw.
- Flexible scheduling plus remote access through a top-rated mobile app.
- Clear privacy policy, so personal usage data isn’t sold to third parties.
- Guided DIY install using Bluetooth, which avoids wrestling with router passwords on a tiny wall screen.
Things To Consider
- A c-wire is required, so fuse-box-only or two-wire heating setups may need an adapter or professional help.
- The color screen stays on but at low brightness, so wall placement matters in bright rooms.

Consider Something Else When
Shoppers with high-voltage electric baseboards should look at the Mysa Smart Thermostat for Electric Baseboards, since the Sensi Touch 2 isn’t designed for that wiring.
The entry-level Nest Thermostat keeps things simple without stripping out the features most people want. The mirrored face looks subtle on most walls, and the rotating ring is the only physical control you really need once the schedule is set. The included trim plate and steel mounting plate cover most retrofit situations, including walls with an exposed electrical box.
Where this model earns its everyday-favorite status is the auto-away logic. The thermostat notices when nobody’s home and relaxes the setpoint (the target temperature you’ve chosen) to save energy. Compared to the Sensi Touch 2 above, the Nest leans more on app-based scheduling and less on a physical touchscreen, so most of your adjustments happen through the Google Home app on your phone.
A Few Highlights
- ENERGY STAR certification for verified efficiency.
- Auto-away feature reduces heating or cooling when the house is empty.
- Bundle includes a trim plate plus a steel plate for electrical-box retrofits.
- Schedule built through the Google Home app on Android or iPhone.
Honest Caveats
- Most configuration happens in the app, which is a downside for shoppers who prefer hardware buttons.
- Auto-away behavior depends on phone-location signals, so households without consistent mobile use may see less savings.
- The mirrored face collects fingerprints, which may bother design-focused shoppers.
Right Fit For
First-time smart thermostat shoppers who already use the Google Home app and want a clean, app-driven experience.
Look Elsewhere When
Voice-control lovers who want a built-in assistant should consider the ecobee4 Smart Thermostat with Room Sensor, since it has Alexa built right in.
Honeywell’s RTH9585WF turns the thermostat into a piece of wall décor. The full-color touchscreen is the headline feature, and you can swap backgrounds to match paint, wood tones, or seasonal moods. The included wall plate fills in gaps left by older thermostats, which is a small touch that makes a real difference on retrofits.
Compatibility is the strength here. The unit supports forced-air systems (gas, oil, or electric), hot water and steam, plus heat pumps with electric backup. The one notable exclusion is electric baseboard heat at 120 to 240 volts, which is the high-voltage wiring covered by the Mysa reviewed later. For most central HVAC setups, though, this Honeywell slot in without drama.
Where It Delivers
- Customizable color display blends into styled interiors.
- Wide HVAC compatibility, from forced air to heat pumps with electric backup.
- Flexible programming for personal schedules or utility peak-rate windows.
- Bright, intuitive touchscreen that doesn’t require app access for basic changes.
- Included wall plate covers paint gaps left by older thermostats.
Points To Note
- Doesn’t work with 120 to 240-volt electric baseboard heat, which is the standard high-voltage setup in many older apartments.
- The color screen draws more standby power than simpler monochrome units.
- Programming depth is high, which may overwhelm first-time users.
Made For
Decorator-minded households with central HVAC who want the thermostat to look as intentional as the rest of the room.
Skip It When
High-voltage electric baseboard owners should consider the Mysa Smart Thermostat for Electric Baseboards instead.
The Nest Learning Thermostat is the model that put this whole category on the map. The polished steel ring rotates with a satisfying click, and the display has a higher pixel density than the entry-level Nest above. Once installed, it watches how you adjust the temperature throughout the day and starts building a schedule on its own, which is the “learning” promise in plain terms.
Beyond the schedule, the HVAC monitoring is the sleeper feature. The unit tracks how long your system runs each cycle and pushes an alert when patterns suggest something is off, like a furnace that won’t quite reach setpoint or an AC that short-cycles. For households that want the thermostat to actually think for them, this is the most hands-off option in the roundup.
The Good Stuff
- Self-learning schedule builds itself from your daily adjustments.
- Home/Away Assist drops to an Eco Temperature after you leave, reducing waste.
- Energy History is viewable on the phone or through Quick View on the display.
- The Nest Leaf icon signals when a chosen temperature saves energy.
- HVAC monitoring alerts flag unusual system behavior early.
- Polished steel finish feels more substantial than plastic-bodied alternatives.
Factors To Consider
- Premium pricing puts it out of reach for shoppers on tight budgets.
- The learning algorithm takes a week or two of consistent use before it becomes accurate.
- Most configuration depends on the Google Home app, similar to the entry-level Nest.
Key Specs
Who Will Love This
Busy homeowners who want the thermostat to build its own schedule and quietly watch the heating system in the background.
Reach For A Different Pick When
Shoppers who’d rather not pay the premium should consider the Sensi Touch ST75 Smart Thermostat (Black), which handles scheduling without the learning overhead.
Mysa solves a problem most smart thermostats ignore: high-voltage electric baseboard heat. Standard 24-volt thermostats cannot safely switch the 120 to 240-volt circuits these heaters run on, which is why so many older apartments still rely on manual dials. Mysa slots directly into that gap, supporting loads up to 1900 watts at 120V or 3800 watts at 240V.
The companion app is genuinely free, with no subscription tier for scheduling or remote access. Humidity and temperature alerts round out the package, which is the main reason it makes the humidity-control shortlist. Compared to the Honeywell RTH9585WF reviewed above, the Mysa targets a much narrower audience, but for that audience it’s the most capable option available.
Well-Handled Touches
- Built specifically for 120 to 240V electric baseboard and fan-forced heaters.
- App is free with no subscription fees for remote control or scheduling.
- Compatible with HomeKit, Alexa, and Google Home ecosystems.
- Temperature and humidity alerts notify you when indoor conditions drift.
- Wi-Fi programmable for both daily routines and away periods.
Practical Considerations
- Requires at least four wires including a neutral or second live wire, which excludes older two-wire installations.
- Does not work with low-voltage heating systems, despite the smart-thermostat branding.
- Compatibility checking matters here; shoppers must confirm their wiring before purchase.
- Each zone needs its own Mysa unit, which raises the total cost for whole-home installs.
Feature Card
Best Suited To
Apartment dwellers and homeowners with high-voltage electric baseboards or fan-forced heaters who want app control without rewiring the panel.
A Better Fit Elsewhere
Anyone with central HVAC should look at the Google Nest Thermostat (Snow) + Trim Kit for a broader compatibility profile.
The FocusPRO wireless kit is a different beast from the touchscreens above. Instead of relying on Wi-Fi and an app, the thermostat talks to an Equipment Interface Module (EIM) mounted near your furnace using Honeywell’s RedLINK wireless technology, which is a proprietary radio frequency that avoids the Wi-Fi band entirely. That makes it useful in homes where pulling new wire through finished walls isn’t practical.
The kit also includes a return air sensor that maintains safe temperatures during a power loss, holding 62°F for heating and 82°F for cooling. For households that have dealt with frozen pipes or overheated rooms during outages, that fail-safe is the real story. This is more of an installer-grade product than a DIY pick, which shapes who should consider it.
Points In Its Favor
- Wireless communication removes the need to run new thermostat wire.
- RedLINK technology operates on a dedicated radio frequency for reliable connectivity.
- Return air sensor maintains safe temperatures during a power loss.
- Equipment Interface Module centralizes HVAC wiring for cleaner service.
Worth Bearing In Mind
- Requires 24V HVAC equipment, which excludes most electric baseboard systems.
- More complex installation makes this less suited to casual DIY projects.
- No Wi-Fi or app layer in the base kit, depending on configuration.
Perfect Match For
Renovation projects and retrofit homes where running new thermostat wire through finished walls isn’t an option.
Swap It Out When
Shoppers looking for a more straightforward app-driven upgrade should consider the Sensi Touch ST75 Smart Thermostat (Black) instead.
The original Sensi Touch (ST75) predates the 2023 refresh covered earlier, and it’s still a solid pick for shoppers who don’t need the latest model. The touchscreen color display looks at home in modern kitchens, and the app has earned its strong reputation over several hardware generations. Emerson’s century of HVAC experience shows in how the system handles scheduling quirks.
Privacy is the headline here. Sensi thermostats explicitly state they won’t sell personal information to third parties, which matters more to some shoppers than features. Compared to the Honeywell RTH9585WF, the Sensi Touch is more restrained visually but offers clearer privacy terms and a slightly friendlier install flow. For homeowners who value straightforward behavior, the ST75 still earns its place on the shortlist.
Notable Upsides
- Strong data privacy stance with no third-party data sales.
- Color touchscreen that’s easy to read across the room.
- Top-rated mobile app with reliable scheduling tools.
- ENERGY STAR certification for verified efficiency.
- Works with Alexa for voice control integration.
Trade-Offs To Consider
- Requires a c-wire, similar to the newer Sensi Touch 2.
- Current availability has been intermittent on some listings.
- Lacks the multi-room sensor support of the 2023 refresh without separate purchases.
Quick Facts
Who Should Grab It
Privacy-focused homeowners who want proven scheduling tools and don’t need the latest hardware generation.
Where A Sibling Pick Shines
Shoppers planning to add multi-room sensors should consider the Sensi Touch 2 Smart Thermostat (2023) for native sensor support.
The ecobee4 was the first widely sold smart thermostat with a voice assistant built into the wall unit itself. You can ask Alexa to adjust the temperature without needing a separate Echo device, which keeps the side table clear. The included room sensor is the bigger story, since it lets the thermostat average readings from multiple rooms or focus on the spaces you actually use.
ecobee’s strength has always been whole-home comfort logic. Instead of trusting a single wall reading, the system blends data from the thermostat and any paired sensors to deliver a more even temperature across the floor plan. Compared to the Nest Learning Thermostat above, the ecobee4 trades some learning polish for a built-in speaker and microphone array.
A Strong Showing
- Built-in Alexa voice assistant for hands-free adjustments.
- Room sensor included for multi-zone temperature averaging.
- Whole-home comfort logic balances readings across rooms.
- Compatible with major smart-home platforms.
Some Limits To Know
- Voice assistant adds microphone and speaker hardware, which may not suit privacy-focused shoppers.
- The base unit is larger than simpler thermostats, so wall placement needs more open space.
- Older generation compared to current ecobee flagships, which may matter for feature parity.
Built With In Mind
Households that want a single device to handle thermostat, room sensor, and voice assistant duties.
Not Your Match When
Privacy-focused shoppers should consider the Sensi Touch ST75 Smart Thermostat (Black), which avoids built-in microphones.
The Alarm.com Smart Thermostat is built for households that already lean on the Alarm.com security and automation platform. Rather than standing alone, the unit ties into the same app that controls door sensors, cameras, and alarm panels, which keeps home management in one place. Custom schedules and remote access come standard.
The standout features are the geo-services automation and critical temperature alerts. Geo-services trigger temperature changes based on your phone’s location, so the house can start warming up as you head home. Critical temperature alerts push a notification if indoor conditions cross dangerous thresholds, which is useful for vacation homes or households with pets.
The Helpful Details
- Ties directly into Alarm.com security and automation platforms.
- Custom schedules handled through the same app as alarms and cameras.
- Remote access from anywhere with an internet connection.
- Critical temperature alerts flag dangerous indoor conditions.
- Geo-services automation adjusts based on phone location.
Where It May Fall Short
- Best value requires an existing Alarm.com service subscription.
- Standalone features are thinner than consumer-focused competitors.
Whose Shelf It Belongs On
Households already running Alarm.com for security who want their thermostat to live in the same app.
Reach For A Different Pick When
Shoppers without a security subscription should consider the Google Nest Thermostat (Snow) + Trim Kit for a self-contained setup.
What To Weigh Before Buying Smart Thermostats With Humidity Control
HVAC Compatibility Comes First
Every thermostat on this list targets specific equipment, and getting that wrong is the most common buying mistake. Forced-air, hot water, steam, and heat pumps are standard fare. High-voltage electric baseboards require dedicated hardware like the Mysa. Before anything else, confirm your system voltage and wiring.
Humidity Is More Than A Bonus Number
A humidity reading you never act on doesn’t change comfort. Look for units that trigger alerts at set thresholds, integrate with a whole-home humidifier or dehumidifier, or feed humidity data into the scheduling logic. The Mysa and the Honeywell RTH9585WF both surface humidity data more visibly than simpler models.
Ecosystem Fit Shapes Daily Use
Voice assistants, security platforms, and existing apps quietly decide whether a new thermostat feels like a natural fit or a constant friction point. ecobee4 leans on Alexa, Alarm.com leans on its own platform, and Nest leans on Google Home. Pick the thermostat that matches the tools already on your phone.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
The biggest mistake is buying a thermostat without checking the wiring. A c-wire requirement can turn a 30-minute swap into a half-day project. Voltage is the second pitfall: a 24V thermostat wired to a 240V baseboard is a safety hazard, not just a compatibility issue. Confirm wiring and voltage before clicking through to the listing.
Where The Extra Money Goes
Higher-tier models like the Nest Learning Thermostat and ecobee4 bundle learning algorithms, room sensors, and built-in voice control. The upgrade pays off when you genuinely use those features, and falls flat when the thermostat ends up on a fixed schedule anyway. For most households, a mid-tier unit with the right ecosystem beats a flagship in the wrong one.
Frequently Asked Questions
Do smart thermostats with humidity control actually make a room feel more comfortable?
Yes, because comfort depends on both temperature and moisture. A unit that tracks humidity can trigger a dehumidifier, fan, or AC cycle to pull moisture out of the air, which makes the same setpoint feel cooler without lowering the temperature further.
What wiring do most smart thermostats need?
Most 24V systems require a common wire (c-wire) to keep the Wi-Fi radio powered. High-voltage electric baseboards run on 120 to 240V and need a thermostat rated for that voltage, like the Mysa. Two-wire legacy systems often need an adapter or a professional install.
Can I install these thermostats myself?
Several models are designed for guided DIY install through the companion app, particularly the Sensi Touch line and the Nest Thermostat. The Honeywell FocusPRO wireless kit and Alarm.com thermostat are more installer-oriented due to their component layouts.
Will a smart thermostat work without Wi-Fi?
Most units still function as basic programmable thermostats without a network connection, though app control, learning features, and remote access all depend on Wi-Fi. Schedules saved to the device keep running offline.
How accurate are the humidity sensors in these thermostats?
Wall-mounted humidity sensors typically read within a few percentage points of dedicated hygrometers. Placement matters, so avoid direct sunlight, exterior walls, and locations above heat sources for the most consistent readings.
Wrap Up
Smart thermostats with humidity control reward shoppers who match the hardware to their HVAC system and home layout. The right pick handles your wiring, tracks the conditions you care about, and fits the apps you already use. Start with compatibility, layer in the features you’ll actually touch, and the rest of the decision tends to fall into place.
