As of August 2026, the smart thermostat brands I’d seriously consider are ecobee, Google Nest, Honeywell Home/Resideo, Emerson Sensi, Amazon, plus Mysa/Sensibo/Cielo for special HVAC setups. The “big three” people most commonly cross-shop are still Nest, ecobee, and Honeywell; market/utility documents and ENERGY STAR materials repeatedly identify Google Nest, ecobee, Honeywell/Resideo, and Emerson/Sensi as major connected-thermostat players.

Best picks for most U.S. homes
| Pick | Best for | Why people buy it |
|---|---|---|
| ecobee Smart Thermostat Premium | Best overall for most homes | Excellent remote room sensor system, broad smart-home compatibility, built-in air-quality monitoring, Alexa/Siri voice options, and strong comfort control. It’s often the safest “buy once, cry once” choice if you have uneven rooms. (ecobee.com) |
| Google Nest Learning Thermostat, 4th gen | Best for Google Home / nice design / learning automation | The slickest physical design, learning schedule behavior, Google Home integration, Matter support, and it now comes bundled with the newer Nest Temperature Sensor. (store.google.com) |
| Honeywell Home X8S | Best newer Honeywell premium model | A newer Resideo/Honeywell flagship with a large screen, occupancy/presence detection, air-quality/comfort features, room-sensor support, Matter support, and pro-HVAC brand credibility. (honeywellhome.com) |
| Honeywell Home T9 | Best proven Honeywell sensor system | Older than the X8S but still a very practical, widely used pick: includes/works with room sensors, has a C-wire adapter in the box, touchscreen, Wi‑Fi, ENERGY STAR certification, and utility-reward support. (honeywellhome.com) |
| Emerson Sensi Touch 2 | Best simple, no-drama thermostat | Good if you want smart features without heavy “learning” behavior; supports room/outdoor sensors and has a reputation for straightforward HVAC control. (sensi.copeland.com) |
| Amazon Smart Thermostat | Best cheap Alexa-first option | Worth considering if you mostly want app/Alexa control and basic scheduling at a low price, but it’s less full-featured than ecobee/Nest/Honeywell and is best for simpler systems. |
| Mysa V2 | Electric baseboard / line-voltage heat | Don’t buy Nest/ecobee for 120/240V electric baseboard heaters; Mysa is built for line-voltage electric baseboard, fan-forced, convector, and radiant-ceiling heaters. (getmysa.com) |
| Sensibo Air Pro or Cielo Breez Max | Mini-split / window / portable AC with IR remote | These are not normal central-HVAC thermostats; they make ductless mini-splits and remote-controlled AC/heat-pump units smart via infrared control. (support.sensibo.com) |
My short recommendation
If you just want the best all-around smart thermostat, buy the ecobee Smart Thermostat Premium. If your house has hot/cold rooms, ecobee’s sensor setup is one of the biggest real-world advantages.
If you’re deep in Google Home and care about looks, get the Nest Learning Thermostat 4th gen. Just don’t buy old used 1st/2nd-gen Nest Learning Thermostats—Google ended support for those older models in 2025. (consumerreports.org)
If you trust traditional HVAC brands or may want installer support, get Honeywell Home X8S or T9. Honeywell/Resideo is less “Silicon Valley slick” than Nest/ecobee, but it’s very commonly used and respected in HVAC circles.
If you want simple and reliable, look at Sensi Touch 2. If you want cheap and Alexa-based, look at Amazon Smart Thermostat—but confirm wiring compatibility first.
Before buying: check these 4 things
- C-wire: Many smart thermostats work best or require a common wire. If you don’t have one, check whether the model includes or sells a C-wire adapter.
- System type: Central 24V HVAC is different from electric baseboard, mini-split, millivolt fireplace, or proprietary communicating HVAC.
- Remote sensors: If bedrooms are too hot/cold, prioritize ecobee, Nest Learning 4th gen, Honeywell X8S/T9, or Sensi Touch 2 with sensors.
- Utility rebates: Many utilities offer rebates, sometimes enough to make a smart thermostat very cheap. ENERGY STAR says smart thermostats can reduce heating/cooling bills by about 8% on average, around $50/year, depending on use and climate. (consumerreports.org)
