We came across this fantastic review of smart thermostats, that we just had to share. Especially with the snowy weather that hit Portland, OR recently: Review of the Best Smart Thermostats
"All thermostats — smart or not — will heat and cool your home. The goal of smart thermostats is to automate this process, making it less hands-on for you and more efficient for your home. As a perk, many smart thermostats are also compatible with smart home systems and Amazon Alexa, allowing them to do things like check the weather or the evening news."
