I'm having a 433.92 MHz standard remote control which uses "rolling code" encoding.
Are other "rolling code" encoding standard remote controls interoperable, or do I need a more detailed description of the "rolling code" (like a chip modal number, for ex. HCS301 / HCS300 / HCS200) and perhaps some other things?
So the question is: "Does having both remotes with the same chip (for example HSC301) working on the same 433.92MHz frequency, make them compatible with respect to copying (duplicating)?"
After some research my guess would be no, because I guess that different remotes might have different encoding algorithms (algorithms of rolling code progression), which might be proprietary.
