Editor's Pick: No need to worry if you forget to adjust the temperature when you leave — it detects when no one is home and automatically lowers the temperature. Before you head back, use your phone to turn on the heat or AC in advance, so you walk into a comfortable temperature. Set a weekly schedule and it runs automatically based on your habits. Once connected to Google Home, everyone in the household can adjust it from their phone or tablet. It also monitors your heating or AC system's performance and alerts you promptly if there's an issue, so you don't have to wait until it breaks down to find out.
