Why We Love It
Smart Lighting Without
the Complexity
Smart bulbs are great, but smart switches are smarter. Replace your existing switch and every bulb in that fixture becomes "smart" — even regular LED bulbs. Here's what sets the EP25 apart.
Voice Control
Say "Alexa, dim the living room to 40%" and it just works. Full integration with Amazon Alexa and Google Home — no extra setup required.
Works with Any Bulb
Unlike smart bulbs, this switch makes any LED bulb in the fixture "smart." Switch brands, save money on bulbs, no ecosystem lock-in.
Energy Monitoring
Track real-time and historical power usage per switch. See exactly how much each light circuit costs you — a feature usually reserved for $60+ switches.
Schedules & Scenes
Auto-dim at 9pm, sunrise simulation in the morning, or a "movie mode" that dims to 20% with one tap. Create unlimited schedules from the free Kasa app.
DIY Install — 20 Min
Replaces your existing wall switch with no electrician needed. Detailed step-by-step instructions included. Requires a neutral wire (most homes built after 1985 have one).
2-Pack Value
Comes as a 2-pack — cover two rooms for the price of one premium single switch. Great for pairing living room + bedroom, or hallway + staircase.
✓ Pros
- Makes ANY bulb in the fixture smart — huge flexibility
- Energy monitoring at this price point is exceptional
- Smooth dimming with no flicker on most LED bulbs
- 2-pack gives great value — covers two rooms
- Alexa + Google Home support out of the box
- App is clean, fast, and reliable
✗ Cons
- Requires neutral wire (check your existing switch)
- No Apple HomeKit / Siri support
- Not compatible with 3-way switch setups without add-on
- Some LED bulbs may buzz at low dim levels
Our Verdict: The Smartest Upgrade for Any Room
Smart switches beat smart bulbs for most rooms — you get voice control and automation for all the bulbs in a fixture at once, and you can still use the physical switch normally. The EP25 adds energy monitoring that we haven't seen at this price elsewhere. The 2-pack deal makes it hard to beat on value. If you have neutral wire and use Alexa or Google Home, this is the switch to buy.
