Solux, NRG and Ellard Binding


I have a roof blind with an Ellard motor in it. Essentially, it is very similar to a Somfy motor. I know that it operates on the 433.92MHz frequency but have no information on the wireless protocol used.

I believe that Solux, NRG Automation and Ellard are all the same group of companies and same protocol, but can’t find any information about it.

Does anyone know anything that might help me with this?
