Ecobee Room Sensors: Complete Guide
Ecobee’s room sensors solve the biggest smart thermostat problem: the thermostat is in the hallway, but you live in
the bedroom. Here’s how they work.

What Are Ecobee SmartSensors?
SmartSensors are wireless devices that detect temperature and occupancy in individual rooms. Place them throughout
your home, and Ecobee balances temperature based on where you actually are.
What They Do
| Feature | Capability |
|---|---|
| Temperature Sensing | Reports room temperature to thermostat |
| Occupancy Detection | Detects if room is occupied |
| Smart Away | Triggers away mode when all sensors detect empty home |
| Follow Me | Prioritizes temperature in occupied rooms |
How They Work
- Place sensors in key rooms: Bedrooms, living room, home office
- Ecobee averages temperatures: Uses sensor data to calculate “real” home temperature
- Occupancy adjusts priority: Focuses on rooms where you actually are
- Smart Away triggers: If all sensors detect no motion for 2 hours, switches to away mode
Pricing
| Package | Sensors | Price |
|---|---|---|
| Ecobee Premium (includes sensor) | 1 | $250 total |
| SmartSensor 2-pack | 2 | $80 |
| SmartSensor for Doors/Windows | 2 | $80 |
Sensor Placement Tips
Best Locations:
- Bedrooms: Critical for comfortable sleeping
- Living room: Where you spend most time
- Home office: If you work from home
- Baby’s room: Stable temperature matters
Avoid:
- Near windows (temperature fluctuates)
- Near vents (false readings)
- In closets or storage areas
- Above heat sources (appliances, electronics)
Mounting:
- 4-5 feet off the floor
- On interior walls (not exterior)
- Stand on shelf or mount with included hardware
Comfort Settings
Temperature Source Options:
- Average of all sensors: Balances whole home
- Specific room priority: Focus on bedroom at night
- Follow Me: Auto-prioritize occupied rooms
Schedule Integration:
You can use different sensors for different times:
- Day: Use living room + office sensors
- Night: Use bedroom sensor only
Ecobee Sensors vs Nest Sensors
| Feature | Ecobee SmartSensor | Nest Temperature Sensor |
|---|---|---|
| Temperature | ✅ | ✅ |
| Occupancy Detection | ✅ Yes | ❌ No |
| Included with Thermostat | 1 included | Sold separately |
| Price (2-pack) | $80 | $40 (3-pack) |
Ecobee sensors are smarter because they detect occupancy—allowing automatic adjustments based on
where people are.
Real-World Benefits
Problems Sensors Solve
- Thermostat in hallway reads 72°F, bedroom is 65°F
- Upstairs is always hotter than downstairs
- Guest room wastes energy when empty
- You forget to adjust temperature when leaving
Limitations
- Can’t create true zones with single HVAC system
- Can only balance, not independently control rooms
- Motion detection has 30-minute timeout
How Many Sensors Do You Need?
| Home Size | Recommended Sensors |
|---|---|
| 1 bedroom apartment | 1-2 (included + bedroom) |
| 2-3 bedroom home | 3-4 (master, kids, living) |
| 4+ bedroom home | 4-6+ (key rooms only) |
You don’t need one in every room. Focus on rooms where you spend the most time and have temperature
issues.
Verdict
Ecobee SmartSensors are worth it if: You have temperature imbalances, hot/cold spots, or want
automatic away detection.
Skip sensors if: Your home has consistent temperatures or you have true zoned HVAC.
