What smart appliances are worth buying?

Smart refrigerators with internal cameras let you see what is inside from your phone, but they are expensive and the feature is more convenience than necessity. Smart ovens that preheat remotely and notify you when food is ready can be useful for busy families. Smart washing machines that let you start a load from your phone are convenient but not essential. The smart appliances that deliver the most value are those that save energy or offer remote monitoring. Focus on appliances you use daily rather than gimmicks.
