Leviton Voice Dimmer vs Smart 3-Way Wi-Fi
Smart Home Compatibility
The Leviton Decora Smart Voice Dimmer (Product A) supports Alexa and Google Assistant, but the product data explicitly notes it does not work with Apple Home. In contrast, the Leviton Decora Smart 3-Way Wi-Fi Dimmer (Product B) lists compatibility with Alexa, Google Assistant, and Apple Siri. Product B also mentions support for SmartThings, Sonos, and Resideo, with Matter support enabled via a firmware update. This broader ecosystem support gives Product B a clear advantage for users invested in the Apple or Matter standards.
Built-in Voice Assistant
Product A features Alexa built directly into the device. You can ask it to dim lights, play music, check the weather, or control other smart home devices without needing a separate speaker. The data does not list any built-in voice assistant for Product B. While Product B works with voice assistants via the app or external devices, it lacks the standalone voice command capability of Product A. If you want direct voice control from the switch itself, Product A is the superior choice for this specific function.
Connectivity Protocol
Both devices connect via Wi-Fi. Product A is listed with Wi-Fi connectivity and supports Alexa and Google Assistant. Product B also uses Wi-Fi but highlights Matter support as a key feature, which can be enabled through the My Leviton app. Matter provides a unified standard for smart home devices, potentially offering easier integration with various hubs and ecosystems compared to standard Wi-Fi alone. Since both rely on Wi-Fi for primary connection, the distinction lies in the future-proofing offered by Product B's Matter capability.
Dimming Load Capacity
Product A has a maximum load rating of 300W for dimmable LED loads. The data for Product B does not specify a maximum wattage or load limit. Both are dimmer switches designed for LED compatibility. Without explicit data for Product B, we cannot confirm if it matches the 300W limit of Product A. You should check the Product B packaging or manual for its specific load rating to ensure it meets your lighting needs. Based on the provided data, Product A offers a clearly stated capacity.
Physical Dimensions
Product A measures 2 inches in width, 4 inches in height, and 1.35 inches in length, weighing 8 ounces. Product B is wider at 2.63 inches, taller at 6.19 inches, and deeper at 3.88 inches, weighing 9.49 ounces. Product B is physically larger in all dimensions. This size difference may affect fit in tight electrical boxes. Product A has a more compact footprint, which might be preferable for standard single-gang installations where space is limited. The choice depends on your box depth and width constraints.
Which Leviton dimmer fits your setup

If you want granular control over light output and smooth transitions, this spec-focused approach suits your needs best.
