What to know about this device before choosing a connection.
A recommendation is not recorded yet. Compare the requirements below with your home and the capabilities you need.
Neutral-required lighting dimmer: 150 W LED or 300 W incandescent. Ratings checked in the US support-linked manual, PDF page 15. No general-current or motor rating is inferred. Documentation reviewed October 16, 2026. Active means manufacturer listing observed; stock, independent certification and physical-device testing are not established. Home Assistant support-list membership does not approve an exact native or Matter route. Match model, region, hardware and firmware before use. Manufacturer-documented Tapo app functions: schedules, Away Mode. These are vendor-app/catalog features; their Home Assistant, Matter or other integration exposure has not been reviewed for this device. Auto-Off and a generic timer are not treated as proof of a countdown timer. This device is not compatible with 3-way wiring. The manufacturer describes optional wireless-button expansion with a separately sold Tapo Smart Button and a required Tapo hub; this is separate equipment, not 3-way wiring support.
Check your ecosystem, then choose a connection method for its requirements and available controls.
