The Nest smart thermostat is a great option to save energy on your electric bill by automating your thermostat.
The LED display makes up the majority of the surface and can display an analog or digital clock instead of the temperature if you prefer.
It will start to automatically adjust to your homes temperature based on the activity in your house and time of day etc.
Another cool benefit is that you can control the unit through a smartphone app – Connect your thermostat to Wi‑Fi to control the temperature from your phone, tablet or laptop. So, for example if you’re in bed and are cold/hot you can make adjustments etc. without getting up. Nice.
Installation is straightforward, and only takes about 15 minutes.
