433Mhz Intertechno decoder

Hello,

Tried with many library to decode an Intertechno remote 433MHz.

RCswitch see nothing at all. (my board is ok because other remote are well decoded!)

No success with remote switch.

Strange it's not an rolling code !
See some diagrams here_

12bits protocol:

Any idea for other library to use ?

Thanks!

You first have to determine the type of signal modulation. Here is a good tutorial.

Thanks,

tried with the program sniffing bits but no result. it sees nothing!

But as far as I know it’s 32 bits lang
