The Best Smart Thermostats of 2025: Top Picks for Every Home

The Nest Thermostat 4th Gen earned its high 9.5/10 rating in our testing for a reason: the bezel-free 2.7-inch LCD with dynamic weather animations feels premium and the included Nest Temperature Sensor helps tame hot and cold spots around the house. During our review we appreciated Matter certification and wide smart-home compatibility, including HomeKit, plus robust energy monitoring and smart scheduling. Downsides we found: it leans toward the pricier end (listed on Google Store) and it lacks a Thread radio, relying on Wi‑Fi for Matter.

The ecobee Smart Thermostat Enhanced is a great value at about $189 and scored 8/10 in our testing thanks to easy installation and proven energy-saving routines that can cut HVAC costs by up to 26%. During our review we liked its broad platform support (Alexa, Google, HomeKit) and intuitive app, but we found the lack of built‑in voice control inconvenient — you’ll need a smart speaker for voice commands — and additional SmartSensors for multi‑room balancing are sold separately.

The Sinope TH1124ZB scored 6/10 and in our experience delivers accurate temperature control for electric heating with a professional look that fits modern homes. We appreciated easy integration with SmartThings and Home Assistant for smart scheduling and remote access, but during our review app quirks — like trouble switching modes — and the need for a compatible Zigbee hub added setup friction and extra cost. On‑device controls are limited, so plan to rely on the app or home automation for most adjustments.

The Google Nest Thermostat scored 8.5/10 and in our testing delivers a reliable, no-nonsense smart thermostat with easy installation, broad HVAC support and remote control from your phone. We found its energy monitoring and voice controls (via Google Assistant and Alexa) practical for everyday use, even if it doesn't learn schedules automatically or support external temperature sensors. During our review we noted the design is less premium than other Nest models and that the optional trim plate adds cost, so it's a smart, affordable middle-ground if you want strong performance without premium styling.

The Honeywell Home T9 scored 7.5/10 in our testing and stands out for practical sensor design — its remote sensor runs on common AAA batteries and also measures humidity, which we found genuinely useful for comfort management. During our review the app and smart scheduling made controlling multiple rooms straightforward, and voice control with Alexa, Google Assistant and HomeKit adds flexibility. That said, we noticed the sensor is bulkier than competitors', must be wall-mounted, and the T9 can't mix geofencing with time-block schedules — plus it ships without a wall plate — so plan around those trade-offs.

Mysa scored 7.5/10 in our testing and is a strong choice if you want a clean, app-first experience — it includes a built-in Wi‑Fi adapter (no bridge required) and works with Alexa, Google Assistant and HomeKit. During our review we liked the responsive mobile app and solid energy monitoring, which make managing electric heating loads straightforward. That said, we found the minimalist in‑panel design limits how much information you can see on the device itself, wiring can be more confusing than expected, and it doesn't play with Samsung SmartThings, so check ecosystem fit before buying.

The Smart Thermostat Premium scored 8.5/10 in our review and stands out for integrating an air quality sensor that watches VOCs and CO2 — a real perk if indoor air matters to you. In our testing the device’s energy monitoring, voice control and smart scheduling made daily climate tweaks effortless, but the built-in speaker disappointed for music playback and installation can be thorny if you don’t have a C‑wire. If air quality insights are a priority, this is a strong mid‑range pick.

Sensibo Sky is an affordable way to smarten window or split AC units and scored 6.5/10 in our testing; setup is simple and it works with most air conditioner types and voice assistants like Alexa and Google. Our experience shows real-world convenience for renters or second‑floor units, but advanced capabilities are gated behind a subscription and it won’t connect to 5 GHz Wi‑Fi — a pain if your home uses that band. For the price, it’s handy but not feature‑packed.

The Emerson Sensi Touch Smart Thermostat scored 7/10 and in our testing stood out for straightforward installation, responsive color touchscreen controls, and reliable compatibility with Alexa, Google and HomeKit. During our review it made remote access and scheduling painless, but it does require a C‑wire and some users (including us occasionally) saw the touchscreen behave unresponsive. If your HVAC is modern and you want a competent touchscreen thermostat without advanced learning features, it’s a sensible mid‑range pick.

The BCC100 Smart Thermostat earned a solid 7/10 in our testing thanks to broad HVAC compatibility — it even supports setups with humidifiers and dehumidifiers and has a large, easy-to-read touchscreen. During our review we found setup straightforward and voice control via Alexa useful for daily adjustments, and its smart scheduling simplifies comfort without fuss. However, it lacks geofencing and IFTTT integration, and in our experience the requirement for a C‑wire can add installation cost in older homes, so consider your wiring before buying.

The Vine TJ-610E is an ultra-affordable option that in our testing was easy to install—many users finish in under 30 minutes—and its intuitive touchscreen and energy-saving modes can cut HVAC costs by up to 20%. During our review we appreciated the responsive interface and smart scheduling, but the model scored only 5.5/10 because frequent Wi‑Fi disconnections and a buggy app undermine day-to-day reliability. It's a tempting low-cost choice with voice control via Google Assistant or Alexa, but our experience shows Wi‑Fi and app glitches can make it frustrating.

The Honeywell Home Smart Thermostat earned a 6.5/10 in our testing and offers a pleasant touch with customizable background colors that let you tailor the look to your home. In our experience the device's remote access and voice control work well for daily adjustments, and its scheduling features cover most needs without extra fuss. During our review we did find the touchscreen can be unresponsive at times and installation may be tricky without a pro, so factor possible setup complexity and occasional tap issues into your decision.

The Sensi Touch 2 Smart Thermostat earned an 8.5/10 in our testing for blending style and substance — the bright, responsive touchscreen and slick app make daily control a pleasure. We found the thermostat’s full feature set (smart scheduling, geofencing, energy monitoring and remote-sensor support) and strong Google/Alexa integration make it a standout value, though remote sensors cost about $40 each and aren’t included. During our review installation required a C‑wire and an adapter kit adds cost, and the lack of a decorative back plate means wall blemishes may show.

The Bosch Smart Thermostat scored 7/10 in our review and is a solid pick if your HVAC setup includes humidifiers or dehumidifiers, since we found compatibility across multiple systems is a real strength. During our testing remote access and voice control via Alexa worked reliably, but the interface felt unintuitive and the unit lacks geofencing, so it won’t automatically adjust based on your location. Also note installation generally requires a C‑wire, which can complicate DIY installs in older homes.

The RENEWRTH6580WF Wi‑Fi Thermostat earned a 6.5/10 and stands out for ENERGY STAR certification and flexible 7‑day programming with up to four periods per day, which in our testing helped fine‑tune comfort and savings. We found voice control via Alexa and Google Assistant handy, but installation may be trickier — it often needs a C‑wire adapter and it’s not compatible with electric baseboard systems (120–240V). During our review some users also reported a loud clicking noise during HVAC transitions, so factor potential operational sound into your decision.

The T10 Pro Smart Thermostat scored 7.5/10 in our review and impressed us with flexible programmability and the Honeywell Home app, which makes remote access and personalized scheduling easy. During our testing RedLINK and Wi‑Fi connectivity options were handy for different installations, but compatibility is narrowly focused on 3H/2C heat pump or 2H/2C conventional systems, so it won’t suit every home. It’s a powerful choice if your HVAC matches its supported configurations, though the physical package is relatively heavy.

The Honeywell T10 Pro scored 7/10 in our testing and impressed us with flexible programmability and robust connectivity options — RedLINK plus Wi‑Fi give multiple ways to tie it into larger systems. During our review the Honeywell Home app made remote access and scheduling straightforward, and included energy monitoring helps track usage over time. Be aware though that compatibility is limited to specific 3H/2C or 2H/2C systems, and its heavier, bulkier package and installation footprint could be a consideration for some homes.

We found the Wiser Air Smart Thermostat appealing for its clean touchscreen interface and strong weather reporting, earning it a solid practical score of 7/10 for everyday use. In our testing it integrated well with Amazon Echo and made remote access and scheduling straightforward, but it requires a C‑wire and isn’t compatible with Google Home, which limits flexibility for some smart-home setups. Also note it prioritizes ‘comfort’ profiles over precise temperature numbers, so expect a different control style.

The Sensi Smart Thermostat is an ultra‑budget option (scoring 5/10 in our review) that works with most 24‑volt AC control systems and gets the basics right for very low cost. Our testing shows it’s fine for simple remote control and scheduling, but it depends on cloud servers for connectivity which limits true local Wi‑Fi control and introduces potential latency or outages. Fan control is basic — just ‘auto’ or ‘on’ — so don’t expect granular HVAC management.

If you want a straightforward, well-integrated option, the ecobee Smart Thermostat Lite scored 8/10 in our testing for good reason: it installs easily for DIYers and the app makes remote control painless. During our review we appreciated its wide platform support — Alexa, Google Assistant and Apple HomeKit — and built-in smart scheduling and energy monitoring that help trim bills. We found the lack of built-in voice and no included room sensors keep it from full-featured status, and limited compatibility with humidifiers or ventilators may matter for some HVAC setups.

The Amazon Smart Thermostat is a budget-friendly pick that scored 6/10 in our testing — its biggest selling points are the low price, tight Alexa integration and simple app-guided DIY installation. During our review we liked how easily it slides into an Echo-centric smart home and how smart scheduling and energy monitoring help manage costs without fuss. We found notable limitations though: it only works with Alexa (no Google Assistant or HomeKit support), lacks remote temperature sensors, and requires a C‑wire, which could force extra wiring work in older houses.

The Honeywell T5 scored 6.5/10 and in our testing proved to be an easy-to-set-up thermostat with practical geofencing that adjusts your comfort when you come and go. We found HomeKit and Alexa compatibility useful for voice control, but the unit requires a C‑wire and some users report intermittent Wi‑Fi connectivity and remote access hiccups. During our review it handled basic scheduling well, yet it lacks the advanced learning algorithms you’ll find in higher‑end models, so expect to manage routines manually.

The Honeywell Home Wi‑Fi Thermostat scored 6/10 in our evaluation and offers reliable basic energy-saving controls with full remote access via the smartphone app. During our review the thermostat handled scheduled setbacks fine and supported both Alexa and Google Assistant for voice control, but we found it lacks advanced automation such as occupancy detection and still typically requires a C‑wire to install. If you want straightforward remote control without premium features, it’s a practical, budget‑minded choice.

The Hive Smart Thermostat Pack scored 7.5/10 and in our testing proved easy to install and use, with helpful geolocation and scheduling features that save energy without fuss. We found it plays nicely with Alexa, Google Assistant and HomeKit, but it lacks motion sensing to detect occupancy and some advanced functions require a Hive Heating Plus subscription. Users have also reported intermittent connectivity dropouts, so expect occasional troubleshooting even though day‑to‑day control is smooth.

The LEVOIT Aura 400S is a budget-friendly smart thermostat with a crisp 4‑inch high-resolution touchscreen that makes everyday control straightforward. In our testing we liked the user-friendly display and features like remote access, voice control, smart scheduling and energy monitoring, and it works with Google Assistant and Alexa. However, we found its 6.5/10 score reflects real concerns: compatibility issues with standard HVAC systems and occasional display quirks have led some users to report malfunctions and costly repairs, so factor potential wiring or system checks into your plan.

The Netatmo Indoor Module is a focused indoor air monitor that scored a 6/10 in our testing — great if you want CO2, temperature and humidity tracking in multiple rooms but not a standalone thermostat. In our experience its long battery life (over a year) and HomeKit compatibility make it easy to place around the house, yet it requires the separate Netatmo Weather Station base unit and is limited to three extra modules per station. During our review we found it useful for targeted air-quality insight, but the dependence on a base unit and susceptibility to high-humidity environments limit its utility for many buyers.

The Vine Smart Thermostat is an ultra-budget option that scored 5.5/10 in our testing: it’s easy to install and has a user-friendly touchscreen, and it supports Alexa and Google Assistant out of the box. Our experience shows the big downside is reliability — frequent Wi‑Fi connectivity problems and a glitchy app can undermine day‑to‑day use — and it still typically requires a C‑wire for power. During our review the convenient price and voice control were attractive, but persistent app and connectivity issues make it a risky buy for critical HVAC control.

The Sensi Smart Thermostat ST55 scored 6.5/10 and in our testing impressed with easy installation, broad platform support (Alexa, Google and HomeKit) and flexible scheduling for everyday comfort. We found the app and remote access work well for routine control, though some users experience Wi‑Fi dropouts and the ST55 lacks learning behavior and geofencing that higher‑scoring models offer. During our review the thermostat does the essentials reliably, but if you want adaptive, sensor‑driven automation you’ll need to look at more advanced options.
