Best for Multi-Room ControlPrice
$60-$80
$150-$200
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.
Comes with a remote room sensor in the box so you can monitor two areas of your home from day one. The best pick for larger homes where one thermostat can't tell the whole story.
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
- Remote room sensor included in the box — no extra purchase needed
- Supports up to 20 additional remote sensors for whole-home coverage
- Compatible with Alexa and Google Assistant
- Packed with features including smart scheduling and geofencing
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
- Bulkier design compared to Nest and Ecobee models
- App experience not as polished as Ecobee or Nest
- Additional sensors sold separately beyond the included one
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 you've ever had a room that's always too hot or too cold, the T9 solves that problem out of the box — no extra purchases required. It's the most practical choice for multi-room households.
