Two years ago, I started playing around with cheap 433MHz plugs that can be found almost everywhere. At that time, I got several from different brands, from the well known Chacon Di-O plugs, to the most obscure chinese/no-name ones, and my goal was to reverse engineer as much protocols as possible. I compiled the result into a little tool I called rf-ctrl (now available on my GitHub), and forgot about it. However, this summer, I needed to find a solution to remotely control my electric heaters (not because I was cold obviously, but because I had the time to do it), and thought it was time to dig up rf-ctrl with a bit of polishing (a Web UI called Home-RF).
