How it differs from the type answer
- In-wall dimmer for one light circuit: dims only, no colour or colour temperature.
- Two customizable scene buttons also show as Matter buttons (single, multi-press, long press, release in telemetry); which presses can start automations depends on the platform.
- Neutral and the included traveler wire are needed for multi-way; one Cync dimmer works with traditional switches on a 3-way circuit.
- Matter over Wi-Fi: no Thread border router needed. Scene and group programming of the buttons in the Cync app is outside Matter.
