I installed this Matter-Certified Smart Dimmer 3-Way Light Switch, Tapo S515D Kit in my hallway where two switches control the same light. Setup was straightforward once I connected it to my Matter hub, and the dimming works smoothly at both locations. The kit includes what you need for a 3-way setup, which saved me from buying extra parts. It responds quickly and hasn't dropped connection so far. A solid pick if you want smart dimming on a multi-switch circuit.
