Coding Universal Remote with existing RF remote?

[Ferra]

I am looking to pickup a universal remote (e.g. logitech harmony one)
Is it possible to code a RF remote that's is not on the logitech supported list?

I brought a wireless remote power outlet for some lighting at home....Fusion Indoor Wireless Remote and Outlets

Is it possible to code it with the logitech harmony remote? If so, how hard is it?
(I know you can just point and learn with a IR remote, but I don't know how RF remotes work)

You need the Harmony 900 to do RF.

It learns keys the same way with RF as it does with IR.
