Summary
The most full-featured smart thermostat available, doubling as a voice assistant, air quality monitor, and home security device. Supports five smart home platforms — more than any competitor.
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
- Supports 5 platforms: Alexa, Apple HomeKit, Google Assistant, IFTTT, and Samsung SmartThings
- Built-in mic and speaker for hands-free Alexa control without a separate smart speaker
- Monitors indoor air quality and can function as a home security device
- Compatible with remote sensors to balance temps across multiple rooms
- 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
- Most expensive option in the smart thermostat category
- Feature set may be overkill for users who just want basic temperature control
- Subscription required for some advanced features
- 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
If you want one device that does everything, this is it. The built-in Alexa speaker, air quality monitoring, and remote sensor support make every other thermostat feel half-baked.
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.
