Open Source Software
“Easy to install, even for a novice DIYer, and effortless to set up with more options than I was expecting for such a simple device. I bought this for monitoring the power usage of my 3D printer and shutting it down when it is finished which it does with no hassle at all and I can even track how much my prints are adding to my energy costs.
I now plan on putting these things everywhere!”
