TP-Link HS110 & HS100 Smart Wi-Fi Plug: What They Are, How They Work, and Which One to Buy
Smart home tech has made its way all the way to your outlets. In this guide, we’ll look at two popular TP-Link Kasa models — HS100 and HS110 — explain how they work, how to set them up, and which one fits your needs.
What is a smart plug?
A smart plug is a compact adapter that goes into a standard wall outlet. You then plug your device (lamp, space heater, coffee maker, etc.) into the smart plug. Once connected to Wi-Fi (2.4 GHz) and the Kasa app, you can turn power on/off, create schedules, set timers, enable Away Mode, and — with the HS110 — track energy usage.
Remote control from anywhere: As long as your phone has internet (Wi-Fi or cellular), you can control the plug via the Kasa cloud — even if you’re in another state or country.
| Feature | HS100 | HS110 |
|---|---|---|
| Remote on/off via Kasa | ✔️ | ✔️ |
| Scheduling, timers, Away Mode | ✔️ | ✔️ |
| Voice control (Alexa, Google Assistant) | ✔️ | ✔️ |
| Energy monitoring (real-time & historical) | ❌ | ✔️ |
| Typical use | Simple on/off automation | Power tracking + automation |
Bottom line:
- Choose HS100 if you just need reliable on/off control and scheduling.
- Choose HS110 if you want energy monitoring to see how much power a device uses and estimate costs
What you can do with a Kasa smart plug
- Automate lighting: Turn lamps on at sunset and off at bedtime.
- Pre-heat or pre-cool: Power a space heater or fan 30–60 minutes before you get home.
- Coffee & kitchen routines: Start the coffee maker at 7:00 AM on weekdays.
- Vacation “Away Mode”: Randomizes on/off to make it look like someone’s home.
- Energy insights (HS110): Identify power-hungry devices and reduce your bill.
Tip: Avoid plugging in high-draw appliances that exceed the plug’s rated amperage/wattage. Always check the device label.
Quick setup (iPhone or Android)
- Plug it in and make sure the LED starts blinking (pairing mode).
- Install Kasa Smart app and sign in/create an account.
- In Kasa, tap “+” → Device → Smart Plug”, follow the prompts to join the plug’s temporary Wi-Fi, then connect it to your 2.4 GHz network.
- Name the plug (e.g., “Living Room Lamp”), assign an icon/room, and finish.
- Optional: Link Alexa or Google Assistant in Kasa to enable voice control.

Troubleshooting tips
- Can’t add the plug in Kasa: Ensure you’re on 2.4 GHz Wi-Fi, not 5 GHz. Move closer to the router during setup.
- Offline in the app: Power-cycle the plug (unplug/replug), then reboot your router.
- LED states confusing: Check LED legend in Kasa → Device settings → Help.
- Network changed? Use the reset procedure and re-onboard to the new SSID.
- Voice control not working: Re-link the Kasa skill (Alexa) or service (Google), and confirm the device name matches your voice command.
Safety notes
- Verify load ratings (amperage/wattage) before connecting heaters or other high-draw devices.
- Do not use outdoors unless the model specifically supports it (HS100/HS110 are indoor).
- Keep away from moisture and heat sources; ensure adequate ventilation.
Verdict
Both TP-Link HS100 and HS110 are easy to set up, reliable, and integrate smoothly with Kasa and major voice assistants. If you only want on/off + schedules, the HS100 is perfect. If you want to track energy usage and make data-driven decisions on power consumption, go with the HS110.
