Smart thermostats can be used for multiple zones to save energy without turning some rooms into ovens or freezers. Bedrooms and other rooms with different insulation or windows are more likely to have a different temperature than a room with the same insulation. The ecobee Smart Thermostat Premium is a thermostat that can pair with room sensors for total home awareness. All of the multi-zone smart thermostats are worth looking into.

The heat should be turned up a tad.

One of the best smart thermostats you can buy is the ecobee Smart Thermostat Premium. It's compatible with all popular smart home platforms and can be controlled via an app on your phone. If you prefer hands-on use, it has a full color touch display.

The ecobee Smart Thermostat Premium has a microphone and can be used as a stand-alone AmazonAlexa device or as a speaker. It tops our list of the best thermostats that support Amazon's voice assistant because it is a smart thermostat and an echo dot in one package. You can make "Intercom-style" announcements with the new Ecobee if you have more than one Echo speaker.

It's one of the easiest smart thermostats to install because it ships with a power extension kit that can be used if a C wire isn't present. Finding the best smart thermostat that doesn't require a C wire can be difficult, and some that don't need one can have power problems. The ecobee Smart Thermostat Premium is one of our favorites because it's comforting to know your thermostat will work as it's supposed to.

The new interface that's easier to navigate and see is a welcome update. There is a zinc body on the glass front. Ecobee has an air quality sensor that it can use to monitor your home's temperature and make sure it's not dirty.

Ecobee 3 lite

The Ecobee 3 lite is a basic smart thermostat that works over the internet with other smart home networks. Ecobee made it compatible with its room sensors and turned it into one of the best smart thermostats. If you want to use room sensors for multi-zone heating and cooling, you need to purchase a set of room sensors or find a bundle that includes them.

The biggest difference between the Ecobee 3 lite and the Ecobee smart thermostat is the lack of voice input, but if you have a more complicated heating and cooling system, you should be aware of the compatibility issues. You might want to look at a different model if you have any of this equipment. The Ecobee 3 lite allows you to start on the cheap with just the thermostat.

Nest Theromstat

With multi-zone capability, the Nest Learning Thermostat is an excellent product for people who need more than one sensor. The temperature can be adjusted according to when you're likely to be at home. It means you won't have to adjust the temperature yourself, and that can lead to substantial savings on your utility bills.

Apple's HomeKit is the only smart home platform that Nest doesn't work with. Black, copper, steel, silver, and white are some of the colors of the third-gen nest. One of our favorites is the thermostat. Despite being several years old, it still holds up against newer devices for energy savings, and its software continues to get updates.

The Nest thermostat is multi-room capable, but not without a compatible room sensor. You will need to purchase more than one in order to control the temperature in a multi- room environment.

Google Nest Thermostat e

Home/Away Assist is a feature of the Nest Thermostat E that can be used to save money on heating and cooling when the house is not occupied. When there is no movement in the room, the E version adjusts, using a sensor that senses the movement in the room. It's cheaper than it's sibling because it has more sensors and requires more adaptation to guess when you're going to head out.

It's compatible with most smart home platforms, including Apple HomeKit, and can be adjusted through the Nest website. You can see how much money is being saved. It's a great device for saving money and there are few drawbacks.

To turn a room into a smart thermostat, you'll need to buy a Nest room sensor. The new Nest Thermostat can't be used as a multi-zone thermostat because it doesn't support sensors, which is one of the reasons to consider it over it.

Honeywell T9 Smart Thermostat

Chances are you have had at least one experience with a product from the company in the past. The smart thermostat can be used to manage the temperature in your various rooms, but you'll probably want to get a few more sensors.

It's easy to manage separate rooms from a single thermostat with the help of these smart room sensors. The Home T9 is packaged with one of those sensors. A basic design with touch controls and smart assistant integration is what you will get.

The Home T9 didn't have a sensor built into it, so you'll want to put the included sensor near the T9. While testing the thermostat, we found that the room sensor did a good job of reporting the temperature of the room it was located in.

The Home T9 does not integrate with your current HomeKit setup so you will want to look elsewhere. You can't use the ability to schedule and set up the same thing. You have to choose one or the other.

Mysa smart thermostat

Ecobee, Nest, and most other smart thermostat makers focus on heating and cooling systems, which keeps people from taking advantage of them. Most of the same perks you would get with a bigger brand-name thermostat can be found in Mysa.

The Mysa Smart Thermostat is easy to install and lets you set automatic schedules, control your temperature remotely, and shut off heat or air when you're not around. The design is meant to blend in more than stand out, but it does allow you to change the room's temperature quickly.

You can control different rooms in the house using the Mysa app. The energy savings from a smart thermostat will be offset by the fact that you need to purchase multiple Mysa thermostats. If you're prepared to spend money in order to save money, it's probably a good idea to have a heating system with multiple thermostats.

Emerson Sensi Touch Lifestyle

The ease of use for the customer is one of the reasons that Emerson's thermostats are so popular. The added features of the Sensi Touch are the same as the other ones.

Your thermostat can be adjusted when you leave or get home with the help of the Sensi touch. If you don't want another option to program your thermostat, you can use a daily schedule. Scheduling will work even if you lose your home's wi-fi connection.

The Sensi Touch doesn't give a lot of information on the display itself. You won't get basic thermostat controls if you can't see what the outside temperature is. If you have a whole- home humidifier, you'll need a separate humidistat to control it, as the Sensi Touch doesn't include this ability.

Keep all of your zones comfortable

The ecobee Smart Thermostat Premium is the best thermostat for multiple zones, according to us. You get the convenience of having a multi-zone heating or cooling system without buying any extra equipment, have AmazonAlexa built into the thermostat itself, and it's more future-proof with HomeKit support. The Ecobee 3 lite is a good way to start if you don't want to spend a lot of money.

If you already use Nest products or would prefer not to have HomeKit support, the Nest Learning Thermostat or Nest Thermostat E and an additional purchase of a Nest Temperature Sensor can save you money.
