    Smart thermostats (温控器)have become the face of smart home technology for most, but depending on what your home is like, it's possible to say the Ecobee3 is superior.

Most of the smart thermostats carry the same benefits, including the Ecobee3. They can learn your preferences and schedules, and then adjust the temperature accordingly. They're better-looking and more enjoyable to use than the basic pieces of plastic that occupy most households. And once you're able to heat up or cool down your house from your phone, without having to get out of bed, you won't want to go back to the past.

If you live in a larger house, the Ecobee3 can be much more convenient—offering you a couple of more remote sensors (传感器). Yes it gets pretty expensive at that point. But having those gives you effective control over the temperature in different rooms around your house. In comparison, other thermostats' measurements are largely limited to the area in which they're installed (安装).

If you live in a smaller place, that's no big deal；the Ecobee3 still has distinct advantages. It is touch-enabled, making it less annoying when you want to enter a Wi-Fi passwords see weather information, and so on.

Still, all the smart thermostats are pretty great. Which one is best just depends on whether you need a whole-home solution or a simpler one. For now, if it's the former, go with the Ecobee3. Their presence will probably make you more conscious about saving energy. Ecobee3 Smarter Wi-Fi Thermostat with Remote Sensor is available at all shopping websites.
