TREATLIFE Smart Light Switch Single Pole Works with Alexa, Google Home and SmartThings, 2.4GHz WiFi Timer Smart Switch, Neutral Wire Required, No Hub Required, FCC Listed, 4 Pack: Four Dumb Switches, One Smarter House

The TREATLIFE smart light switch four-pack is aimed at the homeowner who wants to convert several rooms to voice and app control at once, without paying per-switch premium prices or buying a hub. It suits anyone with neutral wiring in the wall box who wants Alexa, Google Home or SmartThings to handle the lights. This review covers what the four-pack includes, how the wiring requirement shapes the install, what the app and voice controls realistically deliver, and where the switch falls short of pricier alternatives.

The specification sheet is short and honest, and that is the point. This is a single-pole switch, which means it controls one light from one location only — no three-way or multi-switch circuits. The 2.4GHz WiFi radio is standard for this class of device, and the absence of a hub requirement keeps the setup simple for a household that already has a router and a voice assistant.

The neutral wire requirement is the single most important line on the sheet. Many older homes, especially those wired before the 1980s, have switch boxes with only a hot and a load wire and no neutral. Those buyers will need an electrician or a different product. The FCC listing is a basic regulatory checkbox rather than a smart-home feature, but it does mean the switch has cleared US electromagnetic and safety screening.

The four-pack format is what separates this listing from most competitors. Buying four singles from a premium brand can easily cost several times the price of this bundle, so the pack is the value story here. The trade-off is that all four switches are identical single-pole units — a buyer who needs one three-way switch and three single-pole switches cannot mix and match within this box.

Build, Wiring and Installation

The switch is a standard wall-plate form factor, designed to drop into a conventional US switch box and reuse the existing faceplate. The body is plastic with a glass-like touch panel on the front rather than a physical toggle, which means operation is capacitive — a light tap rather than a flip. Buyers who prefer the tactile feel of a mechanical switch should note that difference before ordering.

Installation follows the usual smart-switch pattern: kill the breaker, confirm the wires with a tester, identify line, load, neutral and ground, then wire the switch in and tuck it back into the box. The neutral wire is the one that trips people up — it is required for the switch to draw standby power, and without it the switch will not boot. A box with a bundle of white wires capped together is a good sign; a box with only black wires is not.

Because there is no hub, each switch pairs directly to the 2.4GHz WiFi network through the app. That keeps the parts list short but puts four devices on the router instead of one. A mesh or congested 2.4GHz network can make pairing slow, and the 5GHz band will not work at all — a common stumbling block for buyers used to modern dual-band routers.

Trade-off: The neutral wire requirement rules out a meaningful share of older homes, and the single-pole-only design means multi-way circuits need a different product entirely.

App, Voice Control and Timers

The companion app handles pairing, naming, scheduling and the timer functions. Each switch can be assigned to a room, given a name that the voice assistant recognizes, and put on a schedule — lights on at dusk, off at bedtime, or a countdown timer for a bathroom fan. The timer feature is the practical workhorse here; it turns a plain light into something that behaves like a presence deterrent or a morning wake-up cue.

Voice control through Alexa, Google Home and SmartThings is the headline feature, and it works the way buyers expect: "Alexa, turn off the kitchen lights" or a Google routine that dims the living room at sunset. SmartThings support matters for households already invested in that ecosystem, since it lets the switch join broader automation scenes rather than sitting in its own silo.

The app is functional rather than polished. Buyers coming from a premium ecosystem should expect fewer integrations, no native HomeKit support, and a control experience that is a step behind the big-name platforms. The switch does not dim — this is an on/off model — so any fixture that needs dimming needs a different product.

Trade-off: The app is the weakest part of the package — serviceable for schedules and voice setup, but not the reason to buy this switch.

Who It Suits and Who Should Skip It

This four-pack is built for the buyer converting a whole floor or a whole house at once: a landlord updating a rental, a homeowner who wants the kitchen, living room, hallway and bedroom on voice control in a single order, or anyone who has already confirmed neutral wires in every box they plan to touch. The price per switch is the argument, and the shared app keeps management in one place.

Buyers who should skip it fall into three groups. Anyone with a three-way circuit — a light controlled from two switches — needs a different product. Anyone without neutral wires in the switch box needs an electrician’s assessment first. And anyone who wants dimming, HomeKit, or a premium app experience should budget for a higher tier.

Renters should also think twice. Installing a smart switch is a wiring modification, and it is not a reversible, plug-in change like a smart bulb. A smart plug or smart bulb is the lower-risk path for anyone who does not own the walls.

FAQ

1. Does the TREATLIFE smart light switch require a neutral wire?
   Yes. The switch needs a neutral wire in the wall box to power its WiFi radio. Homes without a neutral in the switch box cannot use this switch without rewiring.

2. Does it work with Alexa and Google Home?
   Yes. The switch is listed as compatible with Amazon Alexa, Google Home and SmartThings, so voice control and routines work through any of those platforms.

3. Is a hub required?
   No. The switch connects directly to a 2.4GHz WiFi network, so no separate hub or bridge is needed.

4. Can this switch be used in a three-way circuit?
   No. It is a single-pole switch, meaning it controls one light from one location. Three-way and multi-switch circuits need a different model.

5. Does the TREATLIFE switch dim lights?
   No. This is an on/off switch, not a dimmer. It works with lights that do not need dimming.

6. What WiFi band does it use?
   The switch uses 2.4GHz WiFi only. It will not connect to a 5GHz network, so the router needs a 2.4GHz band available during setup.

7. How many switches come in the pack?
   Four. The listing is a 4-pack of identical single-pole switches.

8. Can the switches be scheduled or put on a timer?
   Yes. The app includes scheduling and timer functions, so lights can turn on and off automatically.

9. Is the switch FCC listed?
   Yes. The product name lists FCC listing, which covers US regulatory compliance for the device.

10. Can a renter install this switch?
    It is a wired replacement for an existing switch, not a plug-in device. Renters should check with the property owner before modifying wiring.

Bottom Line

The TREATLIFE smart light switch four-pack is the right buy for a homeowner with neutral wiring who wants several rooms on Alexa, Google Home or SmartThings without paying premium per-switch prices or adding a hub. The single-pole limitation and the neutral wire requirement are real filters — buyers with three-way circuits or older wiring should look elsewhere — but for a straightforward single-pole house, the pack delivers the core smart-switch job at a budget-tier price.
