Lutron Diva Smart Dimmer Light Switch with Wallplate for Caseta Lighting (Lutron Smart Hub Required), for LED Lights, 150W, Single-Pole/3-Way, No Neutral, White (DVRFW-6L-WH-A)

Lutron is the go-to for smart home lighting. I have over 30 devices, rock solid, integrated with HA and HomeKit, and completely independent of cloud services. This is what you want, no question. And if you need three-way or more switches, this accessory switch can be paired with it.
