I need a smart thermostat with remote room sensors.

Two standout options dominate the market for smart thermostats that natively support remote room sensors, each offering a fantastic ecosystem fit depending on your setup.

Add to listEcobee Smart Thermostat Premium (or the more budget-friendly Ecobee Smart Thermostat Enhanced Go to product viewer dialog for this item. ): Widely considered the gold standard for remote sensors. It comes with a SmartSensor included, uses radar-based occupancy and motion detection, and integrates deeply with Apple HomeKit, Alexa, and Google Assistant. You can check availability on The Home Depot or Lowe's.

Add to list A reliable, user-friendly alternative with great whole-home range (up to 200 feet for the sensors) and clear people-detection tech to prioritize occupied rooms. You can look at specs and stock on Coastal Farm & Ranch.

To help narrow down which one fits your home best, tell me:

• Do you use a specific smart home ecosystem (Apple HomeKit, Google Home, or Amazon Alexa)?
• Does your current thermostat wiring have a C-wire (common wire) , or are you unsure?

If remote room sensors are a must-have, I’d narrow it to these three:

• ecobee Smart Thermostat Premium with Smart Sensor - $229.99 (The Home Depot)
• Honeywell Home T9 with Room Sensor - $209.99 (Lowe's)
• Google Nest Learning Thermostat 4th Gen with Temperature Sensor - $239.99 (Walmart)

My picks

• 🥇 ecobee Smart Thermostat Premium — best overall. It includes a SmartSensor, lets you prioritize occupied rooms, and has strong Alexa/Google/Apple Home integration plus built-in air-quality monitoring. Current product listings show it around $230–$249.
• 💰 Honeywell Home T9 — best value for room sensing. It supports up to 20 room sensors, and you can prioritize particular rooms; it's particularly good if you have hot/cold spots. A current Lowe's listing has the thermostat + sensor at $209.99.
• 🏠 Google Nest Learning Thermostat 4th Gen — best if you're heavily invested in Google Home. It learns your schedule and works with Nest temperature sensors. Current listings are roughly $240–$260 depending on retailer/bundle.

I'd buy the ecobee Premium unless you have a particular reason to prefer Google/Nest. For a house where the thermostat is in a hallway but, say, the bedroom or upstairs is consistently too hot/cold, ecobee's room-sensor approach is especially useful.

One important caveat: HVAC compatibility and wiring matter. Before buying, I'd check whether you have a C-wire and whether your system is conventional, heat pump, multi-stage, dual-fuel, etc.

If you tell me (1) your HVAC type, (2) whether you have a C-wire, (3) how many rooms you want sensors in, and (4) whether you use Apple Home, Google Home, or Alexa, I can narrow it to the best exact model and current price.

If remote room sensors are a priority, I’d narrow it to these three:

• ecobee Smart Thermostat Premium - $259.99 (Dell)

• Google Nest Learning Thermostat (4th Gen) - $239.99 (The Home Depot)

• Honeywell Home T9 Smart Thermostat - $209.99 (Lowe's)

• 🥇 ecobee Smart Thermostat Premium — best overall. It includes a SmartSensor and can use additional sensors to focus heating/cooling on the rooms you care about. It’s especially good if different rooms have noticeably different temperatures. Current listings are around $250–$260.

• 🥈 Google Nest Learning Thermostat (4th Gen) — best if you use Google Home. It works with Nest Temperature Sensors, and current bundles include one or two sensors. A 2-sensor bundle is currently around $260.

• 🥉 Honeywell Home T9 — best for lots of sensors. It supports up to 20 Smart Room Sensors, making it attractive for larger homes or several problem rooms. A thermostat + sensor is currently around $210.

My pick: ecobee Premium. If your goal is specifically “make the bedroom comfortable at night even though the hallway is a different temperature,” ecobee's room-sensor approach is excellent.

If you tell me (1) whether you have forced-air heat/AC, boiler, heat pump, etc., (2) how many rooms you want sensors in, and (3) whether you use Alexa, Google Home, or Apple Home, I can recommend the exact model and sensor package.

If you want a smart thermostat that supports remote room sensors to eliminate hot/cold spots, two top-tier options dominate the market. Notably, Google Nest thermostats do not natively support remote room sensors anymore, so you'll want to look at ecobee or Honeywell Home.

To help narrow down which one fits your home, tell me:

• What smart home ecosystem do you use most (Apple Home, Google Home, or Amazon Alexa)?
• Do you have a C-wire installed for your current thermostat, or are you looking for something that doesn't require one?

Finding a smart thermostat with remote room sensor support is a great way to eliminate hot and cold spots in your home. Here are the top models currently on the market that support individual room sensors:

Features a refined design, a larger dynamic display, and works seamlessly with the Nest Temperature Sensor (2nd Gen) to prioritize comfort in a specific room.

Comes with an Ecobee SmartSensor included in the box. It features built-in air quality monitoring, Siri/Alexa integration, and radar-based occupancy sensing.

A budget-friendly alternative that still fully supports Ecobee SmartSensors for remote temperature balancing, though it drops a few luxury features like built-in voice assistants and air quality tracking.

Features smart room sensors that detect both temperature and occupancy, automatically prioritizing the rooms you are actually using.

To help narrow down the best choice, tell me:

• Do you have a C-wire (common wire) installed in your current thermostat setup?

If remote room sensors are the priority, I’d narrow it to these three:

ecobee Smart Thermostat Premium

$249.00

Honeywell Home T9

$498.49

Google Nest Learning Thermostat 4th Gen with Temperature Sensors

$259.99

My pick: ecobee Smart Thermostat Premium

It’s the best all-around choice for multi-room comfort. It includes a SmartSensor, which measures temperature and occupancy in another room, and you can add more sensors later. It also works with Alexa, Google Home, and Apple Home. Current listings I found are around $249–$260.

Best for lots of rooms: Honeywell Home T9

The T9 is particularly good if you have significant hot/cold spots or a larger/two-story house. Its remote sensors detect temperature and occupancy, allowing the thermostat to prioritize rooms that are actually occupied.

Best if you're heavily invested in Google: Nest Learning Thermostat

The 4th-gen Nest can use separate Nest Temperature Sensors, but the sensor system is less flexible than ecobee's. I'd choose it primarily if your home already revolves around Google Home.

One important caveat: before buying, we should check your HVAC wiring/system compatibility—especially whether you have a C-wire, heat pump, dual fuel, or multiple stages.

If you tell me (1) your HVAC type, (2) whether you use Apple Home/Alexa/Google, and (3) roughly how many rooms you want sensors in, I can recommend the exact thermostat + sensor setup and find the best current price.

When looking for a smart thermostat that supports remote room sensors to balance hot and cold spots , two major ecosystems dominate the market.

Top options featuring remote room sensors include:

ecobee Smart Thermostat Premium (Best Overall): Widely considered the gold standard for multi-room control. It comes with one ecobee SmartSensor in the box (which measures both temperature and occupancy) and supports up to 32 total sensors. It also includes built-in air quality monitoring, a smart speaker (Alexa/Siri), and excellent smart home ecosystem compatibility (Apple HomeKit, Google Assistant, Alexa, and Matter). If you want a cheaper entry point into the same ecosystem, the ecobee Smart Thermostat Essential Go to product viewer dialog for this item. also supports remote sensors.

Honeywell Home T9 / X8S Go to product viewer dialog for this item. / T10+ Pro Go to product viewer dialog for this item. (Best for Dedicated Room Prioritization): Honeywell's T9 and X8S models come packaged with a Smart Room Sensor that detects both temperature and presence. The higher-end T10+ Pro supports up to 20 indoor RedLINK sensors and integrates advanced indoor air quality controls. They feature strong geofencing and work smoothly with Alexa and Google Assistant.

Google Nest Learning Thermostat (4th Gen) (Best for Automated AI Learning): Nest utilizes a "temperature sensor" approach, though it handles multi-room temperature averaging slightly differently than ecobee. Keep in mind that standalone remote satellite sensors are sometimes sold separately depending on the bundle you choose.

Note: Remote sensors help your system average out temperatures or focus on specific occupied rooms, but they do not magically create independent room-by-room temperatures unless your HVAC system already has physical zone dampers.

To help narrow down the best choice, let me know:

• Which smart home ecosystem do you use most (Apple HomeKit, Google Home, or Amazon Alexa)?
• Do you know if your current thermostat wiring has a C-wire (common wire for power)?
• Roughly how many rooms or zones are you looking to monitor?

If remote room sensors are the priority, I’d narrow it to these three:

ecobee Smart Thermostat Premium

$259.99

Google Nest Learning Thermostat (4th Gen) with Temperature Sensor

$239.99

Honeywell Home T9 Smart Thermostat with Sensor

$179.00

My pick: ecobee Smart Thermostat Premium

It’s the strongest all-around choice for multi-room comfort. The included SmartSensor can detect temperature and occupancy, and ecobee lets the thermostat use sensors in different rooms to help manage hot/cold spots. You can also add additional sensors later.

Best if you use Google: Nest Learning Thermostat

The 4th-gen Nest can use remote Temperature Sensors to prioritize particular rooms and schedules. It's a particularly good fit if your home already revolves around Google Home.

Best value: Honeywell Home T9

The T9 is worth considering if you mainly want room-by-room temperature prioritization without paying for as many premium features. Current listings show the thermostat bundled with a room sensor for around $179.

One important question: what kind of HVAC system do you have (central AC/heat, heat pump, gas furnace, etc.)? If you tell me that—and whether you use Alexa, Google Home, or Apple HomeKit—I can recommend the best specific model and sensor bundle for your setup.
