SmartPlugMonitor is a portable utility that permits you to monitor your Wi-Fi Smart Plugs from your desktop.
Having this utility will give you the ability to track the wattage, voltage, and the current right from your machine. If you are not familiar with Wi-Fi Smart Plugs, they are basically an electrical plug that can be used to remotely control electronic devices that when used in conjunction with their corresponding app can also be used to turn power on and off, etc.
SmartPlugMonitor resides in the systray and gives the ability to monitor and view your TP-LINK HS1XX Series plug from your desktop - the TP-LINK is compatible with Alexa. It does require the IP address for the device to be monitored and you can choose what you would like the utility to monitor. Obviously having one of the available mobile apps does the same thing but this is meant to give you the benefit of not using your mobile device while sitting at your PC.
The author notes that it does not work for Windows 8.
