SmappeeGraph is a free Chrome add-on that allows users to view a real-time graph of a local Smappee energy monitor. Developed by Marko Z., this tool provides a convenient way to monitor energy consumption and track usage patterns.

With SmappeeGraph, users can easily access the real-time data from their Smappee energy monitor through a simple icon displayed in the browser. The add-on also allows users to store a defined amount of datapoints, which can then be visualized in a graph by right-clicking on the icon.

It's important to note that SmappeeGraph is not an official app and is not affiliated with Smappee. However, it offers a valuable tool for Smappee device owners who want to keep a close eye on their energy consumption and make more informed decisions about their usage.

Please note that to fully utilize SmappeeGraph, users will need to purchase a Smappee energy monitor from the official Smappee website.
