1st thing, do you have a Nevo SL or a Nevo S70? Your post was a bit confusing in that regard.

In the Nevo Studio Pro database (for the S70 model) there are codes for the Lutron Maestro which should work for you. Add a new device and then choose "model based setup" and search for Lutron and then Maestro. Add that device and test it out.

Only bad part about IR-based lighting from Lutron (if you have to point at the light switches) is that all the codes work on all the switches, ie:, they are not addressable. Meaning if the switches are in nearby proximity of each other they will all react to the IR codes, regardless if that is your intention or not.
