The Right Light for Every Room with a Smart Dimmer Switch

Swap your current wall switch for a smart dimmer switch and set the brightness for dinner, movie night, or bedtime. Tapo's smart home dimmer switch lineup adds app control over Wi-Fi, schedules, and voice control to the rooms you use most. Renting, or not ready to rewire? A smart dimmer plug gives your lamps the same control.

Why Choose a Tapo Smart Light Dimmer Switch?

  • Wi-Fi Dimmer Switch Control: Change brightness from the Tapo app while on the couch or dim the lights for movie night. Compatible with dimmable LED bulbs.
  • Hands-Free Voice Commands: Adjust the lights while cooking dinner using a smart dimmer switch with Alexa, Google Assistant, or Siri (on select Matter-certified models). Check product details for compatibility.
  • Matter Compatibility: Matter-certified models work with major smart home platforms, including Apple Home, Alexa, Google Home, and Samsung SmartThings, so a Matter dimmer switch fits the setup you’re already using. Some platforms require their own hub.
  • 3-Way Smart Dimmer Switch: Dim one light from two spots, like the top and bottom of a staircase. The S515D Kit pairs a main dimmer switch with an included satellite switch to replace both wall switches.
  • Smart Dimmer Plug for Lamps: The Tapo P135 Kit lets renters dim two lamps at once with a wireless dimmer button, no wiring or hub required. Check product details to confirm both lamps are compatible. 
  • Smart Scheduling: Schedule lights to switch on at dusk and off after the kids' bedtime. Away Mode makes your home look lived in while you travel.
  • App-Guided Installation: Follow the wiring guide to replace your existing switch, a straightforward upgrade if you're comfortable with basic electrical work. If not, an electrician can handle it.

Expand Your Smart Home 

Tapo devices work together in one app, so your lighting options can grow as your smart home expands.

  • Sensor Triggers: Pair the S505D with Tapo smart sensors and a Tapo hub (both sold separately) to light the hallway automatically at night. 
  • Scenes and Schedules: Group your dimmer with other Tapo devices into one scene and control them all at once. Set the ambiance for a dinner party or a quiet evening in with a few taps on your phone. 
  • Camera Check-Ins: Add home security cameras or Wi-Fi security cameras to the Tapo app and let detected motion switch on your lights.
  • Doorbell Visitor Alerts: Greet visitors with smart doorbells, then use an Alexa or Google Assistant routine to turn on the porch light when someone approaches.

FAQ

What is the best Tapo smart dimmer switch for home use?

The right choice depends on your setup. One of Tapo's best-selling smart dimmer switches is the S515D 3-way kit, which controls one light from two spots. For a light with a single switch, the Tapo S505D is a Matter-certified single-pole dimmer, and the plug-in P135 Kit dims two lamps with no wiring at all. All three include app control, voice control, and schedules.
Do Tapo smart dimmer switches require a neutral wire?

Yes. Every Tapo in-wall smart switch needs a neutral wire, which keeps the switch powered so it can stay connected to Wi-Fi. Look inside your switch box before you buy, or ask an electrician if you're not sure. The plug-in P135 Kit skips wall wiring entirely. 
Are Tapo smart dimmer switches compatible with LED bulbs?

Yes. Tapo's in-wall smart dimmer switches work with dimmable LED bulbs for smooth brightness control, though results can vary by bulb. If you're using the P135 Kit, both lamps must match in load and dimming type, which you can confirm on the product page. 
Do Tapo smart dimmer switches work with Alexa and Google Home?

Yes. You can turn lights on or off and set brightness with your voice through Amazon Alexa or Google Home. Select Matter-certified models also work with Apple Home. Check product details for compatibility. 
Can Tapo smart dimmer switches be used as 3-way switches?

Yes, with the right model. The S515D Kit includes two switches, a dimmer and a satellite, so you can control one light from both ends of a hallway. The single-pole S505D doesn't support 3-way wiring, but adding a Tapo Smart Button and a Tapo hub (both sold separately) lets you control it from a second or third location without rewiring.
