Creating complete new IR set

Hi,
I want to create a complete new IR set of devices (fan and diffusor) not available in the IR database yet.
How can I do that?

When I add a new infrared device or new RC in the web configurator I am always asked for the manufacturer. According to the instructions on the Unfolded Circle website there should be a button saying “create blank”. This button is not available!

Ok, found the “create blank” somewhere else!
