It handles up to 600 W on incandescent bulbs or 150 W on LEDs over a 15 A, 100–120 V circuit. The steady 2.4 GHz Wi‑Fi link pairs with popular voice assistants. Its slim body slides into a standard US wall box.
Key Advantages of the S500D Dimmer Fan
Energy-Smart Comfort Made Simple
- energy saving schedules slash wasted kilowatt-hours by turning lights and fans off automatically when no one is home.
- A built-in dimmer delivers whisper-soft fade on/off transitions that protect sleepy eyes and prolong bulb life.
Everyday Convenience in One Panel
The switch needs a neutral wire for steady power. Pair it in seconds with the Tapo app. Then set up scene automation for movie night, bedtime, or a full‑house shut‑down with one tap.
Straightforward Installation
What You Need Before You Begin
With only a screwdriver and the supplied hardware, most DIYers finish the install in under 15 minutes.
Easy install means no trips to the breaker box after setup. The Tapo app guides you through live‑line calibration and firmware updates.
Smarter Control, Anywhere
Voice-Assistant Integration
You can pair the S500D with Alexa, Google Home, or SmartThings. Then hands‑free lighting becomes real. Say, “Turn off the hallway lights,” or “Dim the pendants to 40 percent,” and let your chosen voice assistant take over.
The switch stays online, so the Tapo app can reach it from anywhere. Turn lights on before you arrive home. Or use smart scheduling that follows sunrise, sunset, or a motion sensor.
Robust Design and Safety
Certified Peace of Mind
Every S500D is UL certified, FCC-tested, and RoHS-compliant, meeting stringent electrical and environmental benchmarks for safe indoor use.
The tough PC housing works from 0 °C to 40 °C. If heat climbs too high, built‑in guards shut the circuit. This safety feature is perfect for long holiday scenes.
Future-Proof Compatibility
Ready for Expanding Ecosystems
The switch uses 2.4 GHz Wi‑Fi, so it reaches your router with ease. Free OTA updates will add Matter ready features to keep the switch working with new hubs.
Since the S500D is part of the broader Tapo ecosystem, you can link it with cameras, sensors, and buttons. For example, lower lights when no motion is detected or boost a fan during summer heat.

More Ways the S500D Elevates Your Daily Life
Flexible Lighting for Every Occasion
Beyond basic dimming, the Tapo Smart Wi‑Fi Dimmer Switch S500D supports a wide range of routines that make homes feel more responsive. You can create subtle evening scenes that help you unwind after work or brighter morning scenes to help you feel more alert. The switch adapts to your habits, learning your preferred brightness levels so adjustment becomes second nature. With its stable Wi‑Fi connection, these settings sync across your ecosystem without delay, ensuring every room in your home reflects the comfort you expect.
The S500D is also ideal for open‑concept living areas where multiple lights often need fine‑tuned coordination. Whether you want soft ambient light for reading or lively brightness for gatherings, the dimmer allows you to shift between moods with ease. Because it supports app‑based tuning, you can tailor lighting from the couch, bedroom, or even outside the home, creating a level of flexibility that standard switches cannot match.
Enhanced Safety and Nighttime Visibility
Families with children or elderly residents benefit from the dimmer’s fine‑grained controls. Setting lights to a low‑level glow during nighttime hours limits harsh glare and prevents trips or collisions. You can schedule gentle transitions before sunrise to avoid sudden brightness when someone steps into the hallway early in the morning. These simple touches add practical safety without adding cost or complexity.
Motion‑based automation makes late‑night navigation easier too. If you connect the dimmer to compatible sensors, lights can fade on automatically when movement is detected, guiding you quietly through your home. When no activity is sensed, the lights fade back off, saving energy while maintaining accessibility and comfort after dark.
Ideal for Multi‑Room Expansion
Homeowners planning to expand their smart home setups find the S500D a reliable starting point. Its broad compatibility ensures it can serve as a foundation for an expanding network of smart lights, plugs, sensors, and cameras. Because the dimmer integrates smoothly with scenes and automation routines, adding more devices becomes a natural next step rather than a complicated upgrade. This scalability makes the switch an appealing long‑term investment that grows with your lifestyle.

The dimmer switch puts smooth lighting control into a small package. It turns ordinary rooms into responsive, comfortable, and efficient spaces you will enjoy every day. If you want to save money, set the mood quickly, or enjoy hands‑free convenience, the Tapo ecosystem is ready. The device is compact, stylish, and built to last. Upgrade once and enjoy it for years.
