Rademacher DuoFern?

Hello all,

Just came across this topic while looking for some DuoFern protocol hack.
I’m also evaluating buying a Rademacher RolloTron Basis DuoFern but don’t want another (expensive) controller in my setup.
I wonder how this topic have evolved.

I could understand DuoFern is in the 433Mhz range. It should be easy to copy it unless it has a rolling code, which I doubt. Have anyone meanwhile tried to copy the RF signals with one of those RF remotes that copy signals?
Or maybe with one of those broadlink RM remotes?

Any suggestion or update will be appreciated.

Cheers

When I was researching for this topic it looked like the protocol is encrypted (rolling code?) and could not be “hacked”.
So I do not think there is another solution for this.

But I can tell you this solution has worked perfectly, fast and very very stable for the last 5 years for me.
I only had to re-pair one device after a black out.

I‘m using this solution - it only requires the Rademacher USB stick which will be connected to the Raspberry (I run OH3 on). And some minor local installation of e.g. Python:
