The best smart thermostat allows one to control the heating or to cool even one is not at home. By connecting the conditioning and heating system to the internet, one can use a voice assistant or smartphone to adjust the temperature in the house, ensuring that no energy or money is wasted just by heating an empty home because the homeowner is late.
These are two different types of smart thermostats. One that controls the cooling and heating system as a whole, and the other one is more expensive and ensures control of temperature in each room individually.
When choosing the best smart thermostat, there is a wide choice from models that can leave you feeling perplexed. Smart thermostat reviews of brands like Honeywell, Nest, and Eco bee, reveal several designs.
Five best smart thermostats of 2021
Nest Learning Thermostat
The Nest Learning Thermostat strikes the right balance between smart and style, making it the best smart thermostat to buy. It learns the routines of the homeowner and accordingly adjusts itself. So, the homeowner does not have to do anything as the thermostat adapts and does everything automatically.
It also has location-based features and tracks where a mobile phone is and turns the heating on or off depending on how far the mobile is from home. Its inbuilt sensor will detect if a guest is at home not freeze when the homeowner is out. The device does not offer zonal control, so one must adjust individual radiators manually.
The Honeywell Evohome offers total control over the home, where there are individual thermostats for every radiator that enables one to set an independent heating schedule for each room. If one lives in a house where each member prefers a different temperature, this device is a boon.
It works with under-floor heating, so if one has a large and complicated heating system, then Evohome gives complete control over all via App. The radiator and control panel comes in plain white plastic, but that’s unimportant. It is expensive as one will need an intelligent valve for each radiator in the room.
Tado Smart Thermostat
It is an easy-to-use smart thermostat with a simple white design, and you can use it with an additional radiator valve for zonal purposes.
It stands out as it is one of those few smart thermostats that work with Google Assistant, Alexa, and Apple’s HomeKit. If one is a proud owner of a Home Pod or a firm supporter of the Apple ecosystem, then this is undoubtedly the best smart thermostat in this category. This device is not intuitive for navigation, and you can compare it to Evohome, but it is challenging to operate. There are also no self-learning capabilities.
Nest Thermostat E
This thermostat is Wi-Fi and Bluetooth enabled but lacks zonal control and no self-learning capabilities. However, it is cheaper than the original Nest and has a simple to use App. The plastic screen can also be hard to read with the white coating on top of it. This model is the cheaper version of the Nest Learning Thermostat and lacks only the advanced feature of the premium model. The quality of the flagship model is missing, but still, it is an excellent value for money.
Ecobee Smart Thermostat with voice control
It is the best home thermostat with a built-in Alexa, and the only issue is that it is not widely available. The Smart Thermostat with voice features is worth your smart home setup. Thanks to a software update, the smart thermostat also offers access to Siri, although one will need a Home Pod Mini in the home to process the requests.
It is not only a great thermostat that can save on energy bills each month, but it doubles as Alexa and its 10,000-strong library of skills or Siri with all its home automation that Apple’s voice assistant can bring. It is self-learning, easy to self-learning install adjust the schedule accordingly as it learns how quickly a house heats up and cools down.
Though Ecobee Smart Thermostat may not have the same clout that Nest learning has gained in the last few years, it remains one of the best thermostats on the market today.
