Top 5 Best Smart Thermostats for Your Smart Home

Updated: Apr 19, 2023

A smart thermostat enables you to adjust the temperature of your home remotely from anywhere in the world. Some models even have the ability to pre-heat your home before you arrive and automatically turn off when you leave, helping you save on energy costs. We have compiled a list of the top smart thermostats that cater to various budgets and premium models that seamlessly integrate with any smart home ecosystem.

It's essential to determine if a smart thermostat is compatible with your current HVAC and power systems before purchasing one. Failure to do so may result in difficulties with the installation process.

Can You Install a Smart Thermostat in Your Home?

It's worth noting that the majority of smart thermostats available today are only compatible with low-voltage power systems. To determine if your current thermostat is compatible, you can remove the cover faceplate and check the listed voltage. If the voltage is 100V or higher, most smart thermostats won't be compatible with your system.

Another way to identify a high-voltage system is by checking if your current thermostat has only two wires or if you have thick wires that are capped or stranded. If either of these is the case, it's likely that you have a high-voltage system that may not be compatible with most smart thermostats.

In addition to the voltage and power system compatibility, it's important to note that many smart thermostats require a "C wire" (or "common wire") for power. If your current thermostat doesn't have a C wire, you may be able to purchase an adapter, but there's no guarantee that it will work with your specific HVAC system. It's best to consult with a professional HVAC technician or the manufacturer of the smart thermostat to determine the best course of action.

The Amazon Smart Thermostat is an affordable option with some high-end features and is compatible with Alexa. With Alexa Hunches, this smart thermostat uses artificial intelligence to learn your routines and automatically adjust the temperature when you're home, away, or asleep.

However, the Amazon Smart Thermostat lacks a built-in speaker and can only be controlled via voice commands with an Alexa smart speaker. Additionally, it's not compatible with temperature sensors, which means you can't set up different temperature zones around your home. Lastly, the Alexa app doesn't allow for individual control of multiple thermostats, so you can only set a single temperature for your entire home.
