Smart plugs were made for you to be able to remotely control your devices and to help you lessen your electricity bills by doing so. That said, not every smart plug comes with an energy monitoring feature, but this TP-LINK Wi-Fi Smart Plug with Energy Monitoring does. Using an app, you will learn how your appliances contribute to the monthly bills and you can take proper action. Also, this smart plug has an Away-Mode in case you're going away on a vacation in which it turns your lights on and off as if there are people in your home. That's not only smart for you, that's smart for the world as well.
This particular TP-Link smart plug has been warmly reviewed by users. According to them, it seamlessly integrates with Echo and works as expected. One user even said that it's better than more expensive WeMo outlets. However, there are some users who claim there is basically no tech support or customer service with this device at all. Overall this product receives a total rating of 4.1 out of 5 stars on Amazon.
