I'll add that sticking with 3rd party gear that your dealer is already very familiar with is some of the best advice you can get. Sure, your dealer *can* integrate the less expensive thing, but you don't want to be the guinea pig that pays for your dealer's education.
In a lot of cases, the 'dealer recommended' product will be less expensive in the long run (even if more expensive up front) because the dealer doesn't need to spend time to figure it out or make a driver, manually configure it, etc.
That's one of the reasons Control4 lighting, for example, can in some cases still be economical compared to less expensive alternatives. The electrician installs them (same as any other dimmer, no additional wiring), the dealer adds the free driver and taps the top button 4 times to learn, and it's fully in the system. No figuring out drivers, no manual configuration (like for Lutron / KNX 3rd party lighting), etc.
