GHome Smart WP3-A Review
Many smart plugs still require a 2.4GHz-only connection during setup. However, the GHome Smart WP3-A supports both 2.4GHz and 5GHz WiFi. As a result, Alexa and Google Home users get a more flexible way to automate four compatible indoor devices.
Price, availability, seller, shipping, and return terms can change. Confirm the current Amazon listing before buying.
Product Overview
The WP3-A is a compact indoor WiFi outlet adapter. It turns compatible plug-in appliances on or off through the GHome app, schedules, timers, Alexa, or Google Assistant. In addition, the four-pack helps buyers automate several outlets without adding a separate hub.
The WP3-A is best suited to Alexa or Google Home households with a dual-band or mesh router. More importantly, the product manual confirms both 2.4GHz and 5GHz support. In contrast, many comparable WiFi plugs remain 2.4GHz-only.
Read the WP3-A user manualHowever, Matter, Apple Home, HomeKit, Siri, and energy monitoring are not listed for this model in the official materials reviewed. Therefore, choose a different plug when any of those features is essential.
Key Benefits
For example, use 5GHz near the router or 2.4GHz when longer reach through walls is more useful. Therefore, setup may be easier than with a 2.4GHz-only smart plug.
The manual lists 120V, 15A maximum input and 1800W maximum resistive output. Nevertheless, appliance type, startup current, and manufacturer instructions still matter.
In addition, use the GHome app to check status and switch compatible devices from your phone when the plug and network services are available.
For instance, automate simple on/off routines for lamps, seasonal lights, and other compatible devices instead of switching them manually every day.
First, add the plug to GHome. Next, link the account to Alexa or Google Home for voice commands and compatible routines.
Moreover, the four-pack can automate several rooms or device groups in one purchase, provided each connected appliance is suitable for remote power control.

Buying Guide
Because a smart plug cannot press an electronic power button, the appliance must safely resume when outlet power returns.
Moreover, do not rely on wattage alone. Instead, check resistive, motor, compressor, and heating-load requirements in the appliance manual.
Choose WP3-A for Alexa or Google Home. However, choose a Matter- or Apple-compatible model when those platforms are required.
For example, use 5GHz close to the router and 2.4GHz where range through walls matters more. First, complete setup near the router.
Since the WP3-A is an indoor device, use a purpose-built outdoor model for patios, yards, garages with moisture, or exposed areas.
Although a four-pack can offer value, it is useful only when several suitable devices need automation. Otherwise, a single premium plug may be better for one outlet.
Expert Setup Tips
Frequently Asked Questions
Yes. The WP3-A manual lists support for both 2.4GHz and 5GHz WiFi. During setup, therefore, select “WP3-A (5G & 2.4G)” in the GHome app rather than the older 2.4GHz-only WP3 option.
Yes. Alexa and Google Assistant are optional. Therefore, you can still control the plug with the GHome app or its physical on/off button after setup.
No separate hub is listed as required. Instead, the plug connects to WiFi and is managed through the GHome app.
The manual lists 120V, 15A maximum input and 1800W maximum resistive output. However, confirm the appliance label, startup current, load type, and unattended-use instructions before connecting it.
Those integrations are not listed for the WP3-A in the official product information reviewed. Therefore, buyers who need Matter or Apple Home should choose a model that explicitly supports those platforms.
Energy monitoring is not listed in the official WP3-A product page or manual reviewed. As a result, treat this model as an on/off automation plug rather than a power meter.
No. The manual states that the plug is for indoor use only. Therefore, do not use it in humid environments or outdoors.
The manual says to use the GHome app version 5.7.0 or later on a phone running iOS 11 or later or Android 6.0 or later. In addition, Bluetooth should be enabled during setup.
First, keep the plug powered. Next, press and hold the reset button for about five seconds until the indicator begins flashing. Finally, reconnect it in the GHome app.
GHomeSmart publishes a one-year limited warranty for qualifying defects under normal use. However, the policy excludes issues such as misuse, improper installation, unauthorized modification, and purchases from unauthorized resellers.
Final Verdict
The GHome Smart WP3-A solves a specific buyer problem. Many mainstream WiFi smart plugs still accept only 2.4GHz connections. In contrast, this model is documented for both 2.4GHz and 5GHz. As a result, its 15A maximum input, schedules, timers, app control, and four-pack format can suit compatible indoor on/off devices.
However, its limitations are equally important. Matter, Apple Home, Siri, energy monitoring, outdoor use, and a motor horsepower rating are not officially listed for this model. Therefore, buyers who need those features should choose a more suitable alternative rather than assuming cross-model compatibility.
