Kasa HS220 vs Feit Electric Smart Dimmer Switch: One Needs a Neutral Wire First

The Kasa HS220 and the Feit Electric Smart Dimmer Switch both replace a standard wall dimmer with one that responds to voice commands and a phone app. They are close enough in function that the decision usually comes down to three things: whether the wall box has a neutral wire, which voice assistant the household already uses, and how much the buyer wants to spend per switch.

This comparison covers the wiring requirements, the app and voice-control side, and the build each one brings to the wall. The short answer sits in the overview below, and the detailed read follows.

The Picks at a Glance

Product	Key Spec	Best Use	Price Tier
Kasa Smart HS220 Dimmer Switch	2.4GHz Wi-Fi, no hub required, single pole, neutral wire needed	Budget-minded buyers wiring a whole room or house	Budget
Feit Electric Smart Dimmer Switch	Wi-Fi dimmer, neutral wire required, Alexa and Google Assistant	Buyers already settled into the Alexa ecosystem	Mid-range

The Kasa sits at the lower price tier and carries the broader feature list on paper. The Feit costs more and leans on its Alexa certification as the headline. Neither is a bad switch; they simply reward different buyers.

Kasa Smart HS220 Dimmer Switch

Connectivity: 2.4GHz Wi-Fi
Hub Required: No
Voice Control: Amazon Alexa and Google Home
Certification: UL Certified
Pole Type: Single pole
Wiring: Neutral wire required
Color: White

The HS220 is a single-pole dimmer, which means it controls one light circuit from one location. Buyers planning a three-way setup — two switches controlling the same light — need a different model, because this one will not work in that configuration. The neutral wire requirement is the other hard gate: older homes sometimes have only line and load in the box, and this switch will not power up without that fourth conductor.

Where the Kasa earns its place is the no-hub design. The switch talks directly to the home Wi-Fi network on the 2.4GHz band, so there is no separate bridge to buy, plug in, or lose. Setup runs through the Kasa app, and once the switch is on the network it answers to Alexa and Google Home without extra hardware. The UL certification is worth noting for anyone installing a smart device inside a wall, since it speaks to the electrical safety testing behind the unit.

Trade-off: The single-pole limitation rules out three-way stairwells and hallways, and the neutral wire demand disqualifies a fair number of older wiring setups before price ever enters the conversation.

Feit Electric Smart Dimmer Switch

Connectivity: Wi-Fi
Model: DIM/WiFi
Voice Control: Amazon Alexa and Google Assistant
Wiring: Neutral wire required
Color: White
Alexa Certification: Certified by Amazon to work with Alexa

The Feit is also a Wi-Fi dimmer that installs in place of a standard switch and requires a neutral wire in the box. It works with both major voice platforms, Alexa and Google Assistant, so a household split between the two is not locked out. The name does not state a pole configuration, so buyers with a three-way circuit should confirm compatibility before ordering rather than assume.

The distinguishing feature here is the Amazon certification. Feit has gone through Amazon’s certification program for Alexa compatibility, which means the switch is validated to pair with Echo devices and respond to voice commands through them. For a buyer who already has Echo speakers in the room and wants the shortest path from box to voice control, that certification is the main reason to pay the higher price. The trade-off is straightforward: the Feit asks for more money than the Kasa without adding a feature the Kasa lacks on the voice side, so the premium buys confidence in the Alexa pairing rather than extra capability.

Trade-off: The higher price is hard to justify on features alone, since the switch covers the same voice platforms and the same neutral-wire requirement as the cheaper Kasa.

Both switches land on the same wiring requirement, which is the first thing any buyer should check. A neutral wire is present in most modern switch boxes, but not all, and neither product offers a no-neutral variant under these model names. The installation job is the same for either switch: cut power at the breaker, confirm the box has a neutral bundle, and wire the new dimmer in place of the old one.

The voice-control row is close to a wash. Both cover Alexa; both cover Google’s assistant under slightly different naming. The difference is the certification. Kasa carries UL certification for the electrical side, Feit carries Amazon certification for the Alexa side. A buyer who cares about safety testing on the device itself will weight the UL mark; a buyer who wants a guaranteed clean Alexa pairing will weight the Amazon certification. Neither mark is a knock on the other product.

The pole type is where the Kasa is more transparent. It states single pole outright, which tells the buyer exactly what it will and will not do. The Feit does not state a pole configuration in its listing name, so a buyer with a multi-switch circuit has to dig further before committing. That is an information gap rather than a confirmed limitation, but it is friction the Kasa does not create.

On price tier, the gap is real. The Kasa sits in the budget bracket and the Feit in the mid-range bracket, and for a room with several dimmers to replace, that difference multiplies. A buyer outfitting a whole floor will feel it; a buyer replacing one switch in a hallway may not care.

Which Should You Buy?

Choose the Kasa HS220 if the wall box has a neutral wire, the circuit is single pole, and the plan involves more than one switch. The lower price tier makes a multi-room install far easier to justify, and the no-hub Wi-Fi design keeps the setup simple. It also suits a household that uses Google Home as much as Alexa, since both are supported without a bridge.

Choose the Feit Electric Smart Dimmer Switch if the house runs on Alexa and the buyer wants the Amazon-certified pairing as reassurance. The higher price is easier to accept when it buys confidence in the voice integration and the install is a single switch rather than a whole floor.

Buy neither if the switch box lacks a neutral wire or the circuit is three-way. Both products require a neutral, and the Kasa is explicitly single pole. In those cases the right move is a different model entirely, not a compromise between these two.

FAQ

1. Do both the Kasa HS220 and the Feit dimmer need a neutral wire?
   Yes. Both product names state a neutral wire requirement, so the wall box must have one for either switch to work.

2. Does either switch need a hub or bridge?
   The Kasa name states no hub required, and it connects over 2.4GHz Wi-Fi. The Feit name does not mention a hub, and it is a Wi-Fi dimmer, so a direct network connection is the expected setup.

3. Which one works with Google Assistant?
   Both. The Kasa name lists Google Home and the Feit name lists Google Assistant — the same platform under two names.

4. Can the Kasa HS220 be used in a three-way circuit?
   No. The name specifies single pole, which means one switch controlling one circuit from one location.

5. What does the UL certification on the Kasa mean?
   It indicates the switch has been tested against recognized electrical safety standards, which matters for a device installed permanently inside a wall.

6. What does the Amazon Alexa certification on the Feit mean?
   It indicates Amazon has validated the switch to work with Alexa-enabled devices such as Echo speakers, so voice pairing is confirmed rather than assumed.

7. Which is cheaper?
   The Kasa sits in the budget price tier and the Feit in the mid-range tier. Current prices are on each product page.

8. Can either dimmer be controlled from a phone?
   Both are smart Wi-Fi switches, so app control from a phone is the core function of each, alongside voice commands.

Bottom Line

For most buyers the Kasa Smart HS220 is the pick: it covers Alexa and Google, needs no hub, carries UL certification, and sits in a lower price tier that makes outfitting several rooms realistic. The Feit Electric Smart Dimmer Switch is a reasonable single-switch choice for an Alexa household that values the Amazon certification, but it asks for more money without adding a capability the Kasa lacks. Confirm the neutral wire and the single-pole circuit first — that check decides more than the price tag does.
