Do Lutron Caseta dimmers really need a hub?
Reviewer consensus
Yes. Across the reviewers we read, the Lutron Smart Hub (or Pro Hub) is required for Caseta and Diva smart dimmers to connect to apps, voice assistants, and HomeKit. Specialist communities view this as a feature, not a bug, because the proprietary Clear Connect radio is the main reason owners describe Caseta as more reliable than Wi-Fi alternatives.
