Why Won't My TP-Link Kasa Smart Plug Respond to Alexa or Google?
- Alexa/Google skill not linked
- Account link expired
- Plug offline (Kasa cloud unreachable)
Problem Description
Your Kasa smart plug works fine through the Kasa app but does not respond to Alexa or Google Home voice commands. The plug turns on and off from the app proving it is connected but voice control says unresponsive. The issue is with the cloud integration link between Kasa and the voice assistant services.
Why This Happens in Real Homes
When a Kasa plug works in the Kasa app but not through Alexa or Google, the plug and its WiFi are fine — the break is in the cloud link between Kasa and the voice assistant. Either the skill/action isn't linked, the account link lapsed, or the assistant hasn't discovered the device.
Link the Kasa skill in Alexa (or the Kasa action in Google Home), signing in with the same TP-Link/Kasa account, then run device discovery so the assistant finds the plug. If control worked before and stopped, re-link the account and re-sync after any device renames. Confirm the plug is online in the Kasa app first — a plug that's dropped off 2.4GHz WiFi won't respond to voice either.
Symptoms
- Works in Kasa app but not Alexa/Google
- Voice control fails
- 'Device not responding' via assistant
- Assistant can't find the plug
- Lost voice control after a change
- Only some commands work
- Delayed voice response
- Skill/account issues
Recognize these? Here's what usually causes it.
Common Causes
- Alexa/Google skill not linked
- Account link expired
- Plug offline (Kasa cloud unreachable)
- Device not discovered by the assistant
- Renamed device out of sync
- 2.4GHz WiFi drop
- Firmware out of date
- Assistant/Kasa account mismatch
Most fixes happen in the first 3 steps.
When re-linking the Kasa skill any custom routines referencing Kasa devices may need to be recreated. Check your routines after re-linking.
Step-by-Step Solution
Re-Link Kasa Account
In the Alexa app go to Skills search for Kasa and Disable Skill. Wait 30 seconds then Enable and sign in again. This refreshes the authentication token. For Google Home go to Settings then Works with Google remove Kasa then re-add by searching and signing in.
Verify Kasa App Control
Confirm you can control the plug from the Kasa app. If the app also cannot control it the issue is WiFi not voice integration. If the app works the problem is isolated to the cloud link between Kasa and your voice assistant.
Rename the Device
Generic names like Light or Plug confuse voice assistants when multiple brands use similar names. Rename to something unique like Kitchen Coffee Plug. Avoid special characters. After renaming ask Alexa or Google to discover devices.
Check Kasa Cloud Status
If all Kasa devices stopped simultaneously the cloud may be down. Check TP-Link forums or downdetector.com. Cloud outages resolve within hours. The Kasa app may still work locally while voice commands go through cloud.
Restart Voice Assistant Device
Unplug your Echo or Google Home speaker for 30 seconds then replug. After boot ask it to discover devices. The speaker itself sometimes loses its smart home skill connections and needs a reboot.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If voice commands stopped working after relinking the account, check that the skill or action is still enabled — relinking sometimes disables it silently.
Group Kasa plugs into rooms in both the Kasa app and voice assistant app. This allows controlling all plugs in a room with one command like Alexa turn off the kitchen.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
