I'm a total noob in electronics field and want to begin. (I'm an IT engineer). I'm trying to use my remote garage door opener (868 MHz HF) to create a system with my Raspberry Pi so I can replicate the signal when I use an Android application (by contacting a web server on my Raspberry). I did some research and found there are two different remotes: DIP switch ones and ones with rolling code where we can't replicate the signal as the code is changing every time. I opened my remote to check and as I'm a total noob, I don't really know how to know which system it's using.
Is it easy to replicate?
