FAQ

Frequently Asked Questions about this product

What is a 3-way smart dimmer switch, and how does it work?

A 3-way smart dimmer switch controls a single light from two different locations in your home. The Tapo S515D kit includes a main dimmer and a satellite switch that work together, letting you adjust brightness from multiple spots, like both ends of a hallway. You also get remote control through your phone and voice assistants.
Does this work with my existing 3-way switch wiring?

The Tapo S515D is designed to work with most standard 3-way wiring setups, but requires a neutral wire to function. If your current 3-way switches have neutral wires available (common in homes built after the 1980s), this switch should be compatible. We recommend checking your wiring compatibility before purchasing or consulting an electrician if you're unsure about your home's electrical configuration.
Can I install this myself, or do I need an electrician?

If you're comfortable with basic electrical work, you can install this yourself using the app-guided instructions. If you're unsure or inexperienced with wiring, consult with a licensed electrician.
What's the difference between Matter-certified and regular smart switches?

Matter certification means this switch works universally across Apple Home, Alexa, Google Assistant, SmartThings, and other Matter-certified devices without platform lock-in. Regular smart switches typically only work with one or two platforms. Matter makes it future-proof—buy once, use everywhere.
How does energy monitoring help me save money?

The energy monitoring dashboard tracks your daily electricity usage with charts in the Tapo app, showing exactly how much energy your lights consume. By identifying usage patterns and estimating costs, you can adjust schedules and reduce waste to lower your electricity bills.
Will this work with my LED bulbs?

Yes, the Tapo S515D works with dimmable LED bulbs, providing smooth, flicker-free dimming from 0-100%. Make sure your bulbs are labeled "dimmable" as non-dimmable LEDs won't work with any dimmer switch.
Do I need a neutral wire for installation?

Yes, this switch requires a neutral wire. Most modern homes (built after the 1980s) have neutral wires in switch boxes. If you're unsure whether yours does, consult a licensed electrician before purchasing.
What's included in the 2-set kit?

The 2-set kit includes one main dimmer switch, one satellite switch, two wall plates, wire labels, five wire nuts, four screws, and a quick-start guide. You get everything needed for two complete 3-way lighting installations.
Can I control brightness with voice commands?

Yes, use voice commands with Siri, Alexa, or Google Assistant to adjust brightness hands-free. Say "dim the hallway lights to 30%" or "set the bedroom to 50%" for instant control.
Does away mode really deter burglars?

Away mode randomly turns lights on and off at different times, creating the appearance that someone is home. While no single security measure is foolproof, visible activity makes homes less attractive targets. Combined with cameras and doorbells, it adds protection for travelers and busy homeowners.
