Connect Amazon Smart Plug to Alexa

Amazon’s own smart plug has the simplest setup since it’s designed to work with Alexa out of the box.

1. Plug the Amazon Smart Plug into a wall outlet. The LED ring pulses blue.
2. Open the Alexa app on your phone.
3. Tap Devices, then “+”, then “Add Device.”
4. Select “Plug,” then “Amazon Smart Plug.”
5. Alexa finds the plug automatically and connects it to your WiFi. If prompted, select your WiFi network and enter the password.
6. Name the plug (example: “Bedroom Lamp” or “Coffee Maker”).
7. Assign it to a room in your Alexa app.

You can now say “Alexa, turn on [plug name]” or “Alexa, turn off [plug name].” Pick descriptive names that are easy to say – “bedroom lamp” works better than “smart plug 1.”

Connect TP-Link Smart Plug to Alexa

1. Set up the TP-Link plug in the Kasa app first (plug it in, open Kasa, tap “+”, follow the WiFi setup prompts).
2. Open the Alexa app.
3. Tap Devices, then “+”, then “Add Device.”
4. Select “Plug,” then “TP-Link Kasa.”
5. Tap “Enable Skill.” The Kasa skill page opens.
6. Sign in with your TP-Link/Kasa account to link it.
7. Alexa discovers your TP-Link plugs. They appear in the Devices section.

For TP-Link Tapo plugs, the process is the same but search for “Tapo” instead of “Kasa” when enabling the skill.

Connect Wemo Smart Plug to Alexa

1. Set up the Wemo plug in the Wemo app first.
2. In the Alexa app, go to Devices, tap “+”, then “Add Device.”
3. Select “Plug,” then “Wemo.”
4. Enable the Wemo skill and sign in with your Wemo account.
5. Alexa discovers your Wemo plugs.

Connect Any Smart Plug to Alexa

The process is the same for virtually all smart plug brands. The general steps:

1. Set up the smart plug in its own app and connect it to WiFi.
2. In the Alexa app, enable the skill for that brand.
3. Link your account.
4. Alexa discovers the plug.

Voice Commands for Smart Plugs

Once connected, you can control the plug with these voice commands:

“Alexa, turn on [name]” – turns the plug on.

“Alexa, turn off [name]” – turns the plug off.

If you are still exploring options, our pair Philips hue with Alexa guide is a solid next read.

“Alexa, turn on [room name]” – turns on all devices assigned to that room.

“Alexa, turn off everything” – turns off all smart home devices.

“Alexa, turn on [name] at 7 AM” – creates a one-time scheduled action.

For the best experience, name your plugs after what’s plugged into them (“coffee maker,” “desk lamp,” “fan”) rather than generic names.

Create Routines With Smart Plugs

Alexa Routines let you automate smart plugs based on time, voice commands, or other triggers.

1. Open the Alexa app and tap “More,” then “Routines.”
2. Tap “+” to create a new routine.
3. Set the trigger: a scheduled time (e.g., 6:30 AM), a voice command (e.g., “Alexa, good morning”), sunrise/sunset, or another smart device event.
4. Add an action: tap “Smart Home,” select your plug, and choose “Power On” or “Power Off.”
5. Save the routine.

Example routines: turn on the coffee maker at 6:30 AM on weekdays, turn off all plugs at 11 PM, turn on the porch light at sunset and off at sunrise, or turn on the bedroom lamp when you say “Alexa, good night” (then turn it off after 30 minutes using a wait action).

Create Groups

Groups let you control multiple plugs with one command.

This topic ties into our Amazon smart plug unresponsive guide, which covers the next steps.

1. In the Alexa app, go to Devices.
2. Tap “+” then “Add Group.”
3. Create a room (e.g., “Living Room”) or custom group (e.g., “All Lights”).
4. Add your smart plugs to the group.
5. Now “Alexa, turn off Living Room” controls all plugs in that group.

Troubleshooting

Alexa can’t discover the plug. Make sure the plug is set up and online in its own app first. Alexa can’t find a plug that isn’t connected to WiFi. Try saying “Alexa, discover devices” or tap “Discover Devices” in the Alexa app. Check that the correct skill is enabled and your account is linked.

Plug shows as “Offline” in Alexa. The plug lost its WiFi connection. Check the plug’s own app to see if it’s online there. If it’s offline everywhere, the plug needs to reconnect to WiFi (restart it by unplugging for 10 seconds). If it’s online in the plug’s app but offline in Alexa, disable and re-enable the skill.

Alexa says “I didn’t find a device named [name].” The device name might not match what you’re saying. Check the exact name in the Alexa app (Devices section). Rename it to something shorter and easier to pronounce. Avoid special characters in device names.

Plug responds slowly to voice commands. This is usually a WiFi issue. Smart plugs on a congested or weak WiFi signal take longer to respond. Move the plug closer to the router or add a WiFi extender. Plugs on a mesh WiFi system generally respond faster than those on a single router with weak coverage.

Do I need an Echo device to use smart plugs with Alexa?

No. You can control smart plugs through the Alexa app on your phone without an Echo. But for voice control, you need an Echo device (Echo Dot, Echo Show, etc.) or another Alexa-enabled speaker within hearing range. The app gives you tap-to-control access from anywhere.

Can Alexa turn a smart plug on and off on a schedule?

Yes. Use Alexa Routines to schedule plug actions by time of day, day of week, or sunrise/sunset. You can also set schedules in the plug’s own app (Kasa, Tapo, Wemo). Either method works – Alexa Routines are easier if you have multiple brands since everything is in one place.

How many smart plugs can Alexa control?

Alexa supports hundreds of smart home devices per account. There’s no practical limit for home use. Each plug connects to your WiFi router, so your router’s device capacity is the real bottleneck – most home routers handle 20 to 50 devices comfortably.
