Summary
The best sub-$100 smart thermostat by a wide margin, with occupancy sensing and Alexa Hunches built in. A no-brainer for Alexa and Ring households.
Nest pioneered the smart thermostat category and the 4th Gen adds improved AI scheduling and a sleek design that works without a C-wire. The go-to pick for anyone deep in the Google ecosystem.
Pros
- Far better technology than other sub-$100 options, including occupancy sensing
- Alexa 'Hunches' can proactively adjust settings to save energy
- Deep integration with Alexa and Ring devices
- Simple installation with C-wire adapter included
- Improved AI Smart Schedule suggests and adapts temperature changes automatically
- Works without a C-wire, making installation easier in older homes
- Attractive, iconic design that blends into any room
- Deep Google Home and Google Assistant integration
Cons
- Best suited for Amazon/Alexa ecosystems — limited cross-platform support
- No remote room sensors available
- Lacks air quality monitoring and advanced scheduling of premium models
- Primarily locked into the Google ecosystem — limited cross-platform support
- No built-in remote room sensors included
- Google has a history of killing connectivity on older Nest devices
Our take
For under $80, nothing comes close. If you're already in the Amazon ecosystem, this is the obvious buy — Alexa Hunches alone make it smarter than thermostats twice the price.
If your home runs on Google, don't overthink it — the Nest Learning Thermostat is the most polished, best-looking option and the AI scheduling actually learns your habits over time.
