The Caseta HomeKit-enabled Wireless Lighting Starter Kit--consisting of the Smart Bridge, two plug-in dimmer modules, and two remote controls--is priced at $230. Similar kits with in-wall dimmers will also be available. Additional plug-in or in-wall dimmers cost $60 each, while additional remote controls cost $15 each. Why would you want a remote when you can use your phone or tablet? In rooms where lighting is under three-way control, you'll need to disconnect the secondary switch if you install a Caseta dimmer. Mount a remote in its place and you won't give up the convenience of having wall switches on multiple entrances to a room.
All the components in the new HomeKit-compatible kits are the same as what Lutron has been shipping since 2014, with the key exception of the bridge. If you've already invested in Lutron's Caseta and Serena products, you'll need to replace the bridge if you want to use Siri to control them. A new bridge will cost $119 (or $200 for the Pro version that can be integrated with other connected-home systems, including certain multi-room audio systems and Logitech's Harmony remote controls).
