Save Money & Stay Cozy: The Smartest Thermostat Deals of Summer 2025

The Sensi Lite Wi‑Fi Thermostat is an affordable, straightforward option that makes a nice entry point into smart climate control. We found the step-by-step app guidance and easy DIY installation particularly helpful for renters and first‑time installers. During our review it scored 6.5/10 because some users experienced Wi‑Fi connectivity problems and the feature set is thinner than premium models. It supports Alexa and Google Assistant and includes geofencing and scheduling, but note it still requires a C‑wire for many systems.

The Sensi Smart Wi‑Fi Thermostat is straightforward to set up, and during our review the app’s scheduling options proved highly customizable for different weekly routines. We found installation guidance to be user-friendly, which makes this a good choice for DIYers who want reliable remote access without fuss. However, it scored 7/10 because it relies on a cloud‑based server rather than local Wi‑Fi control, and lacks motion sensors or learning features that some competitors include.

The Amazon Smart Thermostat is extremely wallet‑friendly and earned a 6/10 as a basic, Alexa‑first option for budget‑minded buyers. In our testing we appreciated the Alexa integration and ENERGY STAR certification, which can help shave about fifty dollars a year from energy bills. However, during our review we found it requires a C‑wire for installation and doesn’t support Google Assistant or HomeKit, limiting ecosystem options. It also lacks remote temperature sensors for true multi‑room control, so factor that in if you’re managing several zones.

At a wallet‑friendly price point, the Nest Thermostat is a smart value pick that scored 7.5/10 during our review. We found installation and setup extremely straightforward and remote control via the app works reliably across most HVAC systems, making it a good choice for first‑time upgraders. Our experience shows it lacks the learning routines and premium aesthetics of higher‑end Nest models, and you’ll pay extra for the trim plate since remote temperature sensors aren’t included. Pick this if you want easy setup and dependable remote access without premium frills.

The ecobee3 Lite strikes a solid balance between price and capability, earning a 7/10 in our testing for straightforward setup and wide platform compatibility. We found the app easy to use and installation is DIY‑friendly, which makes it a good pick if you want remote access without paying for premium features. Our experience shows it doesn’t include SmartSensors in the box and lacks a built‑in voice assistant, so you’ll need sensors or a smart speaker for room‑by‑room management. It’s best for simpler homes where advanced HVAC compatibility isn’t required.

In our testing the SINOPE TH1124ZB impressed with Alexa compatibility and useful energy‑saving features that let you control and schedule temperatures remotely, which is convenient at its $82.75 price. However, we found reliability concerns — some units reported going into overload during extended use — and during our review the requirement for a compatible Zigbee hub reduced its overall price‑to‑value appeal. With a 6.5/10 score it’s a reasonable pick if you already own Zigbee gear, but not the most worry‑free option.

In our testing the Honeywell Home Wi‑Fi Thermostat stood out for broad compatibility — it works with Amazon Alexa, Google Assistant and SmartThings — and the 7‑day, four‑period scheduling really helps tailor comfort across the week. Priced at $69.98 and scoring 7/10, we found installation can be tricky because it requires a C‑wire and initial Wi‑Fi setup sometimes stumbles. During our review it lacked occupancy detection or auto home/away routines, so expect to rely on schedules and manual tweaks for most savings.

We found the Smart WiFi Thermostat attractive for assistant support — it pairs with Siri, Alexa and Google Assistant and offers geofencing and remote access for on‑the‑go adjustments. Priced at $115 and scoring 6/10, during our review the touchscreen was the main drawback: some users reported malfunctions that hurt everyday usability. In our testing the energy‑saving features performed when the touchscreen behaved, but the usability issues make this a middling choice unless you prioritize voice assistant compatibility above on‑device controls.

At $39.99 the Sensi Lite Thermostat is a very affordable way into smart climate control and in our testing the DIY installation and step‑by‑step app guidance were genuinely helpful for renters and first‑time installers. It scored 6.5/10 because our experience shows compatibility is limited with some HVAC setups and heat‑only or cool‑only systems often require a C‑wire. During our review we liked the flexible scheduling, geofencing and voice support (Alexa, Google, SmartThings), but watch the dehumidification mode that can overcool and raise AC runtime.

The ecobee Smart Thermostat Essential is our top‑rated choice in this group — it earned a 9.5/10 thanks to excellent integration with Alexa, Apple HomeKit and Google Assistant and support for optional remote sensors to balance comfort across rooms. In our testing the energy‑saving features delivered measurable reductions (up to about 23%) and remote access was reliable, though during our review we noted it lacks a built‑in Alexa speaker and air‑quality monitoring found on higher‑end ecobee models. At $129.99 it’s arguably the best all‑around value for smart homes.

The Smart Thermostat Enhanced earned its 8.5/10 rating by delivering strong energy savings and wide smart‑home compatibility. In our testing we liked the easy in‑app installation and ENERGY STAR certification that can deliver up to 26% savings on heating and cooling. We found it works with Alexa, Google Assistant and HomeKit, but our experience shows there’s no built‑in voice assistant so a smart speaker is needed for voice control. Also note SmartSensors for multi‑room sensing are sold separately and it may be incompatible with older two‑wire heat‑only systems.

The Google Nest Learning Thermostat is our top premium recommendation, earning a high 9/10 for its sleek redesign, smarter AI, and improved Matter support. In our testing we found the installation process simpler than many competitors since it often avoids the need for a C‑wire, making upgrades easier. During our review the Learning Thermostat’s adaptive routines earned praise, though we found the higher price and occasional connectivity hiccups may give some buyers pause.

The ecobee Smart Thermostat Premium is our top‑tier recommendation — it earned a 9/10 in testing for excellent integration and thoughtful sensors. In our testing the built‑in air quality monitor and included SmartSensor improved comfort and alerted us to poor indoor air. We found its wide compatibility (Alexa, Google, HomeKit, SmartThings and IFTTT) makes it easy to slot into most smart homes, though some advanced home‑monitoring features require a paid Ecobee subscription. Note that geofencing supports only one user and the speaker isn’t ideal for music.

The BCC100 Smart Thermostat attempts broad HVAC coverage, and in our testing we liked that it supports systems with humidifiers and dehumidifiers — a rarity for smart controllers. During our review we found the user experience less refined, and the $295 price combined with a 5.5/10 score makes it a tougher sell compared with sleeker options. It also requires a C‑wire for installation and lacks geofencing, so it won’t automatically adjust when you leave. Consider this if your system needs extra humidification controls and you can tolerate a chunkier interface.

The T10 Pro Smart Thermostat earned a solid 7.5/10 in our review thanks to flexible programmability and the Honeywell Home App that makes remote control simple. We found RedLINK and Wi‑Fi connectivity useful for different installation scenarios, and the customizable schedules let you fine‑tune comfort while saving energy. Our experience shows the tradeoff is HVAC compatibility — it’s intended for 3H/2C heat pump or 2H/2C conventional systems, so double‑check your setup before ordering. If you want deep programming and multiple connectivity options, the T10 is a strong contender.

The Sensi Touch Smart Thermostat is a budget-friendly pick with a bright, responsive touchscreen that makes daily adjustments effortless. In our testing we found its geofencing and Alexa compatibility deliver real convenience for managing comfort when you’re away. During our review the thermostat’s lack of remote room sensor support and requirement for a C-wire limited flexibility in multiroom setups. At a 7.5/10 score it’s a strong value if you want touchscreen ease and voice control, but not ideal for complex zoning.

The Honeywell Home Smart Thermostat offers a fun customizable background and modern look, but in our testing the touchscreen responsiveness was frustratingly sluggish. During our review we found installation could be more complicated than expected, and it requires a C‑wire—so older homes may need extra wiring work. With a 5/10 score it’s best for buyers who prioritize looks and simple screens, but our experience shows there are snappier, more reliable touch interfaces elsewhere.

The Emerson Sensi Touch earned an 8/10 in our testing by delivering a bright, responsive color touchscreen and solid voice‑assistant support. We found geofencing and compatibility with Alexa, Google Assistant and Siri made it easy to automate comfort when you leave or return, and the screen generally makes on‑device adjustments quick. During our review some users reported occasional touchscreen unresponsiveness and the mobile app can feel confusing at first, plus a C‑wire is required for many installs. Overall it’s a dependable, well‑rounded midprice pick if your wiring supports it.

The Sensi Touch 2 scored 8/10 during our review by combining an attractive industrial design with a bright, responsive touchscreen and a full feature set. We found the app and on‑device interface intuitive, and geofencing plus remote sensor support give you strong multiroom control—though those remote sensors cost about $40 each. Our experience shows the thermostat requires a C‑wire and decorative back plate options are missing, so wall imperfections may show and adapters add cost. If you value UI polish and expandability, this one is hard to beat.

Mysa Smart Thermostat blends a sleek industrial look with solid platform support—compatible with Alexa, Google Assistant, and Apple HomeKit. In our testing we liked the easy-to-use mobile app that puts remote access and scheduling right at your fingertips. During our review the minimalist device interface limited on-unit information, and our experience shows the wiring can feel more complicated than older thermostats. It earned a 7.5/10 for good design and cross-platform support, but double-check SmartThings compatibility if that matters to you.

The Honeywell Home T9 is a capable controller that gives robust remote control through its app and fits well into managed property setups. During our review we liked how reliably it connects for remote adjustments and geofencing, which is handy for landlords or busy households. However, it scored 7/10 because the included remote sensor can only mount on a wall with no tabletop stand, and it lacks built‑in smoke detection features.

The Honeywell Home T9 scored 7/10 in our testing by pairing adaptive learning with geofencing to simplify everyday comfort. We found geofencing reliably adjusts temps when you come and go and the adaptive routines grow more useful after a few weeks. Our experience shows the downside: additional sensors are sold separately for proper room balancing and some users report app connectivity hiccups, while the interface feels less intuitive than rivals. Pick the T9 if geofencing and learning are your priorities—just budget for extra sensors.

We found the Mysa LITE to be a practical choice for the right wiring — the step‑by‑step video guidance makes installation approachable and in our testing app schedules could deliver energy savings of up to about 26%. Priced at $84.55 and earning a 7.5/10, our experience shows it requires at least four wires and won’t work with low‑voltage or two‑wire systems, which limits compatibility. During our review the lack of an occupancy sensor meant automation stayed manual, but the strong HomeKit/Alexa/Google support and remote access are definite pluses.

The Honeywell Home T10+ Pro earned its 8/10 in our testing largely for ENERGY STAR certification and solid voice control via Alexa and Google Assistant, and we liked the remote monitoring through the Honeywell Home app. Our experience shows it requires a C‑wire and the app still has a few bugs that can complicate setup and scheduling, and at $185.97 it’s pricier than many rivals. During our review the energy performance and broad compatibility made it a strong midrange contender despite those software and installation caveats.

Sensibo Sky turns a traditional air conditioner into a smart unit that you can control from the app, and it works with Alexa and Google Home. In our testing geofencing and remote access reliably adjusted comfort on the go, but during our review we felt the device’s price seemed high compared with fuller‑featured alternatives. We also found some advanced options require a Sensibo Plus subscription and compatibility can be limited with certain AC models, which hurt its overall value score of 5.5/10.

The Honeywell Home Smart Thermostat is appealing for its customizable color display and smartphone remote control, but it earned a middling 5.5/10 in our testing. We found the touchscreen responsiveness to be inconsistent and installation can be tricky because it requires a C‑wire, so older homes may need wiring work. It pairs with Alexa and Google Assistant for voice control and offers basic energy‑saving scheduling, yet our experience shows the lack of geofencing limits automatic away adjustments. Consider it if looks and remote access matter more than touch performance.

The Hive Smart Thermostat is an easy‑to‑use option that scored 7/10 during our review thanks to its clean app and straightforward installation. We found it integrates well with Alexa, Google Home and Apple HomeKit for voice control and remote scheduling, so day‑to‑day comfort is simple to manage from afar. Our experience shows the catch is that advanced features live behind a Hive Heating Plus subscription and a separate Hive Hub is required for full functionality, which raises total cost. If you prioritize simplicity and platform support, it’s worth considering.

If you’re tying into legacy panels the Lux Smart Z‑Wave Thermostat can be useful — in our testing it connected cleanly with DSC and Qolsys control panels and provided remote access for offsite adjustments. Priced at $250 with a 5.5/10 score, our experience shows the dated design, lightweight plastic and loud clicking buttons undercut the value and daily feel. During our review we noted it lacks voice control and premium build quality, so it’s best suited for compatibility with older systems rather than modern smart‑home aesthetics.
