Somfy and Blyss protocols added to rf-ctrl


The rf-ctrl tool is now able to control plugs and rolling shutter controllers from the well known Somfy and Blyss brands.

Of course, most 433 MHz transmitters work at 433,92 MHz, which is obviously off compared to the 433,42 MHz used by Somfy. However, it works well enough, even if the range is a little bit smaller compared to what you could get with a proper 433,42 MHz transmitter.

Home automation with cheap 433MHz plugs, a 1$ 433MHz transmitter, and a TP-Link TL-WR703N router

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).
