Best Thermostat with Remote Sensor [Top 3 Reviews]

You may be hearing about all these new “smart” thermostats lately. But, do you know the difference between regular, programmable, and smart thermostats?

And what does it mean when a thermostat has a remote sensor?

A quick breakdown for you:

  • Regular thermostats are control panels for your heating and air conditioning system, which you use to adjust the temperature in your home.
  • Programmable thermostats let you set up a heating/cooling schedule several days in advance, and the thermostat changes the temperature for you.
  • The most advanced thermostats are “smart” thermostats.
    They learn your preferred temperatures, adjust the temperature on their own, allow you to control the temperature in your home remotely, and even help you save some money.

Most of the smart thermostats show you monthly energy consumption so you can decide if you are heating/cooling your home unnecessarily and eventually make some changes to receive smaller bills. Some smart thermostats can connect to remote temperature gauges and motion sensors to take that one step further.

This lets the thermostat better understand the temperature in each room and adjust the HVAC system accordingly.

Remote sensors vs. Remote control thermostats

What is the difference between a remote control thermostat and one with remote sensors?

  • Remote control thermostats are connected to wi-fi and can be adjusted using a website or a smartphone app.
  • Remote sensors are used to send temperature information to your thermostat to adjust the heating/cooling based on the information it receives.

Most thermostats are placed in the hallway, and the temperature in the entire house will be dictated by the temperature of the room where the thermostat is set.

That is why the temperature in other rooms may be slightly different; you may end up in a freezing room, and the thermostat will think the temperature is right.

remote thermostat

That is where a remote thermostat sensor comes in.

You can place a sensor in a different room, and it will send temperature and motion information back to the main thermostat. If you’re relaxing in your bedroom and the living room is empty, the thermostat can adjust the settings to avoid wasting energy heating your living room.

Thermostats with remote sensor ability are a much smarter way to control the HVAC system in your home.

Why Are Remote Sensors Valuable?

A wireless remote sensor is handy for heating your entire home optimally and also saving energy.

The sensors measure the temperature in several rooms and help address the troublesome hot and cold spots, keeping you comfortable all the time.

Ecobee4 can support up to 32 sensors, so if you are lucky enough to live in a vast mansion, Ecobee4 has you covered.

The remote sensors do measure not only temperature but also occupancy.

They determine which rooms have people in them to make smart heating and cooling decisions.

Thanks to the sensors, you will be more comfortable at home and save energy when away.

The Ecobee4 remote thermostat sensors also know the difference between humans and pets, so your cat won’t be able to run up your electricity bill.

Ecobee4: a smart thermostat with a remote sensor

The Ecobee4 offers more control than a Nest Thermostat. It works well for large houses because it allows you to control comfort settings for multiple rooms simultaneously.

The sensors allow you to buy one thermostat and additional sensors instead of purchasing multiple thermostat units.

It learns your preferences, allows you to create custom schedules, control every HVAC appliance in your home, and ultimately save you money on your energy bill.

Home IQ Energy Reports

The Ecobee4 has the most advanced energy reports of all smart thermostats on the market. This feature is called Home IQ and can be accessed through the web console.

Home IQ can store up to 18 months of data. Home IQ has two amazing features – Runtime Report and Weather Impact.

The Runtime Report is a monthly report that gives you an estimate of how much energy and money you saved thanks to your smart thermostat with remote sensor.

The Weather Impact will show you how the daily temperature will influence the total run time of your HVAC system.

Advanced Fan Control

Ecobee4 offers advanced fan control options to its users – fan circulate and fan dissipation.

The fan circulates you to specify the number of minutes per hour you want your fan to be turned on. Fan dissipation keeps the fan running for a set time after the heating or air conditioning turns off.

This is because once the HVAC system shuts off, there is still some heating/cooling left. So, immediately shutting the fan would mean wasting a small amount of energy.

Ecobee4 allows you to adjust the amount of time the fan will run (for both options), unlike many other modern thermostats.

Smart Home/Away

The smart home and smart away features are possibly the most advanced features of Ecobee4. The thermostat uses sensors to determine if anyone is present at home and then adjusts the temperature accordingly.

Before using these features, you should set up a weekly schedule and let your thermostat know when you will most likely be at home or away.

However, if the Ecobee4 senses that you are away during a scheduled “at home” period, it will switch to away mode since there is no sense in cooling/heating an empty house.

This feature also works vice versa, meaning that if the sensors detect you during the scheduled “away” period, the thermostat will create a comfortable environment.

Easy-to-Use Interface

ecobee apple watchThe Ecobee4’s interface is straightforward to use both for the thermostat and the app. The sleek design is modern without being obnoxious.

It looks great in homes decorated in any style, from mid-century modern to shabby chic.

Making any adjustments to this thermostat is a piece of cake with a 3.5” LCD touchscreen.

In addition, the display also features smart controls and icons, making the thermostat easy to read and easy to use.

Is Ecobee4 The Best Thermostat with Remote Sensor?

In most cases, a thermostat with a remote wireless sensor function also has the remote control option. This means that even though sensors will do all the work for you, you can still change your settings remotely by using an app.

The significant advantage of the Ecobee4 is the greater control over the temperature in your home. This makes the home comfortable in every room.

It allows you to monitor both humidity and temperature. And ultimately, it saves you energy, which is good for the environment and great for your bank account.

Nest thermostat with Temperature Sensor

Nest thermostats recently had one major disadvantage; unlike the Ecobee4 thermostats, they didn’t support temperature sensors.

As of April 2018, a new Nest product appeared on the market – a temperature sensor compatible with Nest thermostat E and the 3rd gen Nest Learning Thermostat.

You can purchase a single sensor for $39, a pack of three sensors for $99, or even choose a bundle that includes one of the mentioned thermostats and temperature sensors.

In the majority of homes, the temperature varies in each room. Sometimes, your living room can get too warm while your bedroom remains too cold.

Nest wireless thermostat sensor allows you to set the desired temperature during a specific time of the day in up to six rooms.

This means that you can put up to six sensors in your home and schedule each of them according to your needs.

The sensors allow your thermostat to use the temperature in different rooms as the baseline instead of the temperature that your thermostat’s sensor manages to pick up.

One downside to the Nest remote thermostat sensor is that it doesn’t contribute to the Home/Away Assist feature.

This feature automatically adjusts the temperature in your home based on your location.

Unfortunately, the Nest sensors do not have proximity detectors, meaning they cannot notify your thermostat if you’re home or away.

High-Quality Design

Nest is well-known for developing smart devices which look incredibly good and fit in every home. Nest Temperature Sensor features a round design and mimics the shape of the Nest Learning Thermostat.

The device is covered with soft-touch, matte plastic, which looks good and feels solid at the same time. The back of the device is rubberized to ensure that no marks remain on the walls once the device is installed.

In addition, the rubberized back also serves as a grip if you decide to place the device on a flat surface.

Easy Installation

Installation of the Nest Temperature Sensors is effortless. All you have to do is identify the sensor by scanning a QR code that can be found inside the battery cover.

Then, you choose the room where the sensor will be placed, and the Nest app takes care of the rest. Once you connect and activate your sensors, you can access remote temperature reading in the Nest app.

The app will allow you to toggle between the temperature of your programmable thermostat and your remote sensors.

Top-Notch Performance

The Nest allows you to control your thermostat manual and to schedule your thermostat to respond to all of your sensors during the day.

You can create a schedule to ensure the temperature in each room is comfortable according to the time of the day when it will most likely be in use.

The manufacturer allows you to choose one or more of the following time slots for each sensor: morning (7-11 a.m.), midday (11 a.m. to 4 p.m.), evening (4 p.m. to 9 p.m.), and night (9 p.m. to 7 a.m.).


  • Compact and rugged design.
  • Up to six sensors can be connected to a Nest thermostat.
  • The wireless range is excellent.
  • Effortless installation.
  • Easy to use.


  • There are no proximity sensors for detecting motion.
  • The sensors only work with the third-generation Nest Learning Thermostat and Nest Thermostat E.

Nest remote sensors vs. Ecobee4

Nest made the original wi-fi thermostat and changed heating and cooling as we know it. But after a few years, they had some tough competition.

Ecobee was one company whose thermostats went above and beyond the Nest models from a technology perspective. The nest was caught off guard. As of Winter 2018, there is no Nest thermostat with remote sensors.

The company announced its plans to develop a Nest Remote Sens, but we have not seen a new product hit the mark so far. When Nest finally brought their remote sensors to the market, it was pretty underwhelming.

The sensors are not backward compatible with the 1st or 2nd generation Nest thermostats; they only work with 3rd generation thermostats or the low-cost E model.

They’re powered via Bluetooth, so they only have a range of 50 feet. Where Ecobee built a system to control your home’s temperature holistically, Nest built an add-on sensor that helps you out if your thermostat is placed in an inconvenient place in your home.

Nest still would prefer you buy multiple thermostats instead of adding various zone control, which is a shame.

Because of this, we think the Ecobee4 is the best thermostat with remote sensors and the best smart thermostat for large homes.

Honeywell Thermostat with Temperature Sensor

This Honeywell programmable thermostat will not get on your shortlist if you tend to judge products based on their design.

The Honeywell FocusPRO has a traditional rectangular shape and a boring monochrome LCD.

The reason behind this is probably because the Honeywell FocusPRO line isn’t brand new. The manufacturer upgraded it by adding the wireless option to the models that can be programmed.

You can create different schedules for weekdays and weekends or create a different schedule for weekdays, Saturdays, and Sundays. What this unit lacks in design makes up for functionality.

The Honeywell wireless remote thermostat FocusPRO Kit includes the FocusPRO 5-1-1 Programmable Thermostat, Equipment Interface Module, and Return Air Sensor.

Thanks to the addition of a RedLINK Internet Gateway, homeowners can remotely monitor and control their heating and cooling system.

Since the unit is wireless, you can use it to solve any problem from anywhere. In addition, this kit is compatible with other smart home integrations such as Amazon Alexa and Google Home.

Honeywell RedLINK Internet Gateway

RedLINK Internet Gateway allows you to connect your device to the Internet and control it remotely using your PC, smartphone, or tablet.

The manufacturer developed accompanying software, the Honeywell Total Connect system, that sends users alerts and helps them control their home temperature at all times.

In addition, the app allows the user to monitor and control their HVAC system and so humidifiers and dehumidifiers if there are any.

Easy Installation

The Wireless FocusPRO makes it possible for you to install your thermostat anywhere, not only in your hallway or other rooms where you don’t spend much time because of the complicated wiring.

The unit’s installation is effortless –the installation is done at the Equipment Interface Module by the unit itself. This feature makes adding a cooling or multi-stage system a breeze.

Wireless Outdoor Sensor

The RedLINK Wireless Outdoor Sensor enables your thermostat remote sensor to display outdoor temperature and humidity.

The sensor is installed easily – all you have to do is attach it with two simple screws and press a button to initiate wireless installation.

The sensor comes with a weather-resistant cover and lithium batteries that provide reliable performance. The battery life is up to five years.

Thanks to the Wireless Outdoor Sensor, the owners can make temperature adjustments in their home-based on informed decisions and improve their energy savings.

For example, homeowners can turn their HVAC system off to save energy if it is cooler outside than inside.

Return Air Sensor

The batteries that come with your Honeywell FocusPRO can last for a year. But, in case you don’t notice that the batteries are out, or perhaps you forget to change them, this thermostat has got you covered.

Thanks to the Return Air Sens, which works with the Equipment Interface Module, the union maintains comfortable indoor temperatures – 62for heating and 82 for cooling.


  • Simple to use and easy to install.
  • Compatible with Honeywell’s Total Connect system.
  • Displays outdoor temperature and humidity.
  • A wireless unit that allows remote control.
  • The thermostat is programmable and allows users to create their schedules.


  • Outdated design.
  • Doesn’t include zone control.
