Smart thermostats were born in 2011 when Nest took a revolutionary step and introduced a WiFi thermostat to learn and follow the schedule. It was an extreme step that compels competitors to make more innovative products and opens new opportunities for many technology companies to enter this lucrative market. Many things have changed from then to now, and modern-day real smart thermostats can connect with the smart home kits, and Assistants as well can integrate with other supporting smart devices. 

A top-rated smart thermostat can connect with other smart home solutions, learn from your routine, and set a schedule automatically also can detect occupancy, can sense when you are not home-based on motion activation and Geo-fencing to turn off the device as well as can optimize the devices for low power consumption to save on energy bills.

A best-rated smart thermostat can bring a lot of ease in your life; with a home assistant, these thermostats can be controlled with voice, and remote apps provide full access where the owner can see the live setting view reports and can remotely adjust the schedules. The top three in this race are listed below, which are our recommendations as well.

If you are not a fan of big names and want functionality only other than smart scheduling, then Emerson ST55 Smart Thermostat is the best solution for you. We recently reviewed some of the best multi-zone thermostats that you can use to monitor the temperature of different zones inside your house. I believe that every homeowner has something different in mind. To buy the best smart thermostat that can monitor your whole house choice is very limited. 

But if you list all of your requirements, then it will become easy for you to find the right thermostat for yourself. You may also visit cheap smart thermostats to find a cost-effective option.

It is a device that can integrate with all other nest devices, like if you have installed a nest camera in your home, this thermostat can use that camera to detect your presence. Similarly, it can effectively shut off the device when connected with the nest smoke detector, and there is a fire or smoke in the house. 

If you are building a new smart home, I advise you to buy all nest smart devices because they can integrate better and bring you a lot of ease. Alexa connectivity of this thermostat is a plus for you, where you can ask your Alexa to change the temperature or setting. Simultaneously, its app remote control access and enables you to stay connected from a computer mobile or tab.

It works with the standard WiFi and can integrate with all other smart home devices.

I like most of its reporting; I can see energy consumption and all previous reports that help a lot to understand when it is consuming more, that support to decide about a preferred mode for maximum saving on energy bills. Its intelligent sensors can sense when you are not at home to turn off all the devices, and when you get in, they can automatically enable the right mode on your ecobee4.

It may take some time to learn from your preferred setting, but it will provide you with the comfort you expect once it gets all. It’s Alexa enable, so you can directly instruct Alexa to turn it off, or even you can change the setting and mode through Alexa. You may add additional sensors to regulate more zones.

Honeywell Home T9 WIFI Smart Thermostat offers some amazing benefits that are not possible with others. The first one is the range of remote sensors. I always recommend it to those who have really big houses or living in a multi-story house. Other similar capacity smart thermostats come with a sensor range of 50 feet. In comparison, this product offers an amazing range of 200 feet that is really big and enough to automate a large house through a single thermostat.

For multistory building, this is the only solution, and for large houses in which more rooms, you are at liberty to add more sensors.

I personally like to use Microsoft Cortana, especially when I am using my desktop computer. There are many features and things that are only possible with this assistant. I am sure people who are using Cortana are well familiar with this fact. Now, the Honeywell thermostat is fully compatible with Microsoft Cortana and can take instructions from it. I test it with Cortana, and it works smoothly.

Auto Home feature is another advantage that can save you time as well as money. There is no need to switch off the systems when you are going out manually, Honeywell smart thermostat can detect your presence, and when you are out of home, it will turn off all the devices to save energy cost. There is also a built-in energy-saving feature in this device. Its remote control application provides extensive reporting and trigger alerts as you set.

Even there are dozens of heat only and cool the only system that it can handle effectively. During my research, I found that every system used in our country is compatible with the thermostat.

Scheduling and app control are features that are hardly possible at this price, but Emerson is offering these state of art features that will bring a lot of ease to your life.
