The lowest price of the three thermostats we tested, typically well under $100
ENERGY STAR certified, and many utilities offer a rebate on top of the purchase price — worth checking your provider before you buy
Setup and daily control both run through Alexa and the Alexa app, so it's the simplest choice if you're already living in an Alexa household
Has one of the largest review histories of any smart thermostat on Amazon, which is reassuring for a budget pick
Doesn't include a remote room sensor, and the display is smaller and dimmer than the Nest or Ecobee
Fewer non-Alexa integrations than Nest or Ecobee, so it's a better fit if you're not relying on Google Home or Apple HomeKit
Amazon built this thermostat with Honeywell Home, and it’s aimed squarely at people who want the basics of a smart thermostat — remote control, scheduling, energy savings — without paying for room sensors or a built-in voice assistant they may not use.
At under $80, it’s less than a third of the price of the Nest or Ecobee picks above, and it’s ENERGY STAR certified, so it’s eligible for utility rebate programs in many areas even though the federal tax credit for thermostats has expired.

Verdict
This isn't trying to compete with Nest or Ecobee on features — it's trying to get you real smart-thermostat savings and Alexa control for a fraction of the price, and it does that well. If you're already an Alexa household and don't need room-by-room sensing, there's not much reason to spend three times as much on the picks above.
Common Questions
Do I need an Echo device to use the Amazon Smart Thermostat?
You need an Alexa account and the Alexa app to set it up and control it, but you don't need to own a separate Echo speaker — a phone with the app is enough.
Is there a version with a C-wire adapter included?
Yes, Amazon also sells a bundle with a C-Wire Adapter for homes that don't have one; check your wiring before choosing which version to order.
Is the federal tax credit for smart thermostats still available?
No — the federal 25C tax credit that used to apply to smart thermostats has expired. Many utility companies still offer their own rebates, though, so it's worth checking locally.
How does this compare to the pricier Nest and Ecobee models?
It skips extras like room sensors and built-in voice assistants, but covers the core job — automatic scheduling, remote control, and ENERGY STAR savings — at a fraction of the price.
