Kasa Smart Plug HS103P4 Review: Is This Alexa and Google Home 4-Pack Still Worth Buying?

The HS103P4 turns four compatible indoor devices into app-controlled, voice-controlled, and scheduled appliances. It also works without a separate smart-home hub.

However, buyers should understand its 2.4GHz-only Wi-Fi, lack of Matter support, and limited energy information before ordering.

Four rooms, one familiar app, and fewer trips to the wall switch.

Use the Kasa Smart app or a supported voice assistant to manage lamps, fans, humidifiers, and seasonal decorations. Therefore, the four-pack may suit buyers who want simple automation without paying for advanced energy monitoring.

Product overview

What is the Kasa Smart Plug HS103P4?

A four-pack of indoor Wi-Fi smart outlets

The Kasa HS103P4 contains four compact smart plugs that connect directly to a 2.4GHz Wi-Fi network. Each outlet can switch a compatible appliance on or off through the Kasa Smart app.

In addition, users can create schedules, countdown timers, groups, and supported voice-assistant routines. A separate smart-home bridge is not required.

In practice, the plugs work best with indoor lamps, fans, humidifiers, and decorations. Nevertheless, the connected appliance must support switched power and stay within the rating printed on the exact plug.

Benefits and features

Why buyers consider the HS103P4 four-pack

Its strongest value is straightforward multi-room automation without another bridge or complicated control system.

Four-device coverage

For example, one pack can cover a bedroom lamp, living-room fan, office light, and seasonal decoration.

No additional hub

Instead, each plug connects to a compatible 2.4GHz Wi-Fi network and uses the Kasa Smart app.

Remote app control

When connectivity is available, the app can display and change each plug's current power state.

Schedules and timers

As a result, compatible devices can follow recurring routines or switch off after a selected period.

Voice-assistant routines

Furthermore, Alexa or Google Assistant can control clearly named plugs through supported commands and routines.

Compact outlet design

Meanwhile, the mini housing can preserve access to the second receptacle in many standard duplex outlets.

Compatibility and limitations

What buyers should understand before purchasing

It requires 2.4GHz Wi-Fi

The HS103 uses 2.4GHz IEEE 802.11b/g/n Wi-Fi. However, it will not connect directly to a 5GHz-only network.

It does not support Matter

Instead, the HS103P4 focuses on the Kasa app, Alexa, and Google Assistant. Matter-first households should consider a newer certified alternative.

It is not an energy-monitoring plug

Although the app may show operating time, runtime is not the same as live wattage, historical kWh, or electricity-cost tracking.

Hardware-revision warning TP-Link publishes several HS103P4 hardware revisions. In addition, the official specification describes the 15A rating as applying to the newer version. Check official hardware-version resources .

Practical ways to use a Kasa HS103P4 four-pack

Check Current Offer

Buying guide

Six things to check before buying a smart plug

Choose your ecosystem

First, select the HS103P4 for Kasa, Alexa, or Google Assistant. Consider Matter when broader compatibility matters.

Confirm 2.4GHz Wi-Fi

Next, make sure your router provides a usable 2.4GHz connection and compatible security settings.

Match the electrical load

Then check amperage, wattage, motor rating, startup current, and the label on the exact hardware revision.

Decide whether energy data matters

In contrast, choose a monitoring model when you need live watts, historical kWh, or electricity-cost estimates.

Check power-return behavior

Also confirm whether the appliance restarts safely, remains off, or requires a manual button press.

Review seller and warranty terms

Finally, verify the seller, return window, pack size, hardware version, and warranty eligibility.

Setup and usage tips

How to create a cleaner and more reliable setup

Use clear room-and-device names

For example, “Bedroom Lamp” and “Office Fan” are easier for voice assistants and household members to understand.

Pair the plug near your router

Initially, complete setup where the 2.4GHz signal is strong. Afterward, move the plug to its intended location.

Update firmware before building routines

Before relying on schedules, check the hardware version and install any applicable updates.

Test the appliance after a power interruption

Consequently, you will know whether the appliance restarts, remains off, or needs manual control.

Keep essential safety controls independent

Above all, do not use a cloud service or schedule as the only protection against overheating or overloading.

Frequently asked questions

Kasa HS103P4 buyer questions

Compatibility and setup questions

Does the Kasa HS103 work with 5GHz Wi-Fi?

No. The HS103 connects to a 2.4GHz Wi-Fi network. However, a dual-band router can work when its 2.4GHz band is enabled and configured compatibly.

Does the Kasa HS103P4 require a hub?

No separate smart-home hub is required. Instead, each plug connects directly to a compatible 2.4GHz Wi-Fi network and is configured through the Kasa Smart app.

Does the HS103P4 support Matter or Apple Home?

No. The HS103P4 is not a Matter-certified or native Apple Home smart plug. Therefore, Tapo P125M or Kasa KP125M is more suitable for a Matter-based setup.

Does the Kasa HS103 measure energy consumption?

It does not provide detailed live wattage, historical kWh, or electricity-cost monitoring. Instead, choose an energy-monitoring model such as the Kasa KP125M when those features are required.

Will IFTTT continue working with Kasa smart plugs?

TP-Link states that IFTTT service for Kasa and Tapo products is scheduled for full termination on August 1, 2026. Consequently, buyers should use supported Kasa Smart Actions or voice-assistant routines instead.

Electrical use and safety questions

What is the maximum load of the Kasa HS103?

The official specification lists the newer version at 15A resistive at 120VAC and a 1/6 HP motor load. Nevertheless, always follow the rating printed on the exact unit.

Can the Kasa HS103 be used outdoors?

No. It is an indoor-use smart plug. Instead, use a properly weather-rated outdoor plug for patios, landscape lighting, or exposed decorations.

Will the physical button work without internet?

The physical button provides local manual switching. However, remote app control, voice assistants, and cloud-dependent features require compatible connectivity and service availability.

Can two HS103 plugs fit in one duplex outlet?

The compact design can preserve access to both receptacles in many standard vertical duplex outlets. Actual fit, however, depends on outlet orientation, wall plates, and nearby plugs.

Can I use it with a heater, iron, coffee maker, or air conditioner?

Only use those appliances when their instructions, startup current, and the exact plug rating permit it. Above all, do not automate high-heat or high-demand appliances for unattended operation unless the appliance manufacturer expressly allows it.

Package and purchase questions

What comes in the HS103P4 package?

The current product information identifies four HS103 smart plugs plus setup documentation. Before purchasing, confirm the pack size and included components on the seller's listing.

Final verdict

The HS103P4 remains useful for simple four-room automation

The Kasa HS103P4 is a sensible option for buyers who want four indoor smart outlets for Alexa, Google Assistant, app control, schedules, timers, grouping, and Away Mode.

In addition, its compact design and no-hub setup make everyday control easier. However, buyers should not choose it for Matter, Apple Home, long-term IFTTT use, or detailed energy analytics.

Therefore, the final decision depends on priorities. Choose the HS103P4 for basic four-pack value, Tapo P125M for Matter, or Kasa KP125M for Matter plus energy monitoring.
