Lutron Caseta and Lutron RA2 Select, encompass Lutron’s smart lighting, mid-range lineup. The RA2 is almost a complimentary companion of Caseta—and vice versa— as both offerings are identical in many ways. But which is the best option for your home?  

Whether the RA2 or Caseta is best for your home depends on the size of your home and how much you’re willing to spend. However, from a technical standpoint, Lutron RA2 is a serious upgrade over Lutron Caseta. RA2 drastically increases range and the number of devices it handles and adds optional repeaters/extenders.

While the RA2 seeks a happy middle-ground between Caseta and lavish overkill of the RadioRA2, its price is far greater for the sake of 25 additional devices and up to four repeaters. Below, we’ll look at these two devices in detail to help you decide which product is ideal for your home and needs.

Lutron Caseta vs. Lutron RA2 Select: Key Differences

The difference between the RA2 and Caseta is drastic with price, range, and a few more subtle contrasts:

In terms of compatibility and function, there’s not a lot that separates the two:

  • Lutron Caseta requires a standard Smart Bridge, or Smart Bridge Pro, while RA2 uses a Main Repeater.
  • Also, all Lutron products are designed with compatibility in mind. Caseta and RA2 integrate with just about any third-party service and product you can think of, with few exceptions.
    • Serena shades didn’t make the cut with RA2 Select, even though RA2 is an upgrade from Caseta. However, RA2 does incorporate RF Maestro to give you more options and controls over home lighting.
  • Both Caseta and RA2 were designed for DIY enthusiasts. Installing switches and dimmers is simplified through both the Lutron app and the accompanying instruction manual.

Lutron Caseta Repeater

Strangely, the Lutron Caseta Repeater is not often associated with Caseta in reviews or spec information. However, Caseta can add a single repeater, although it only works in conjunction with the Lutron Caseta Smart Home Plug-in Lamp Dimmer Switch.

That’s a lot of words for a single device that complicates the extension of Lutron Caseta’s range. If you think you can purchase an additional smart bridge to add devices and range, know that neither the Caseta nor the RA2 setup is compatible with additional hubs/bridges.

The Lutron RA2, however, is compatible with up to four extenders/repeaters. While an additional 2,500 square feet of a signal range is worthy of a little excitement, you’ll pay for it. An RA2 Select or RadioRA2 Repeater is priced at $229.99. But, RA2’s ability to extend well beyond Caseta’s range is excellent if the price isn’t an overall concern. 

The RF Maestro Switch/Dimmer

RF Maestro switches and dimmers are compatible with Lutron RA2, but not Caseta. While Caseta’s switches and dimmers are multifunctional, the RA2’s Lutron RF Maestro switches and dimmers are next level.

Lutron RF Maestro utilizes touch controls combined with power-loss memory, fade-in and out technology, and is completely programmable. With fade-out or in, turning off the lights will give you a 30 to 60-second delay as the light fades out so you can see your way out of a room.

RF Maestro switches and dimmers retain your settings, even in the event of a power loss. They also work with Pico Remotes and are capable of connecting with up to ten at a time.

Unlike some of the other Lutron RA2 devices and pricey add-ons, the RF Maestro switches and dimmers come with an array of different tech and varying prices, some of which are far more wallet-friendly.

Final Thoughts

In a perfect world, either the Caseta or RA2 lineup would be highly recommended. Lutron is a top-tier company with decades of experience in the home lighting industry.

In reality, it comes down to the size of your home and lighting needs. Lutron RA2 is vastly superior in area coverage and is compatible with better technology via the Lutron RF Maestro devices. If your home is less than 2,500 square feet, there’s probably no need for the RA2, with Caseta more than capable of outstanding coverage.
