5 Best Smart Thermostats

There are many smart thermostats available in the market. But not all are created the same. Others can only perform simple heating and cooling scheduling or programming; while others are capable of more advanced and complex features.

That’s why…

It’s very important that you know first what you’re looking for in a thermostat before you get one. Here are some of the things to consider before getting one:

  1. The price – If you’re willing to spend more money on a feature-rich and premium thermostat, then go buy one. However, if you’re really on a tight budget, there are pretty decent budget-friendly and medium-priced options available.
  2. The features – If you’re contented with simple temperature scheduling and programming, that’s fine. But if you want something more, then get one with more features like controlling ventilation and dehumidifier.
  3. The system – If you’re using Google Home on your smart home devices, then there’s no reason why you should switch to Alexa for your thermostat; and vice versa. So compatibility is another thing to consider. You can check out these Google Home-compatible thermostats for smart climate control.

Having said these, let’s head on to the choices. Rest assured that these are among the best intelligent thermostats today.
