The Kasa plug works in the Kasa app but Alexa says it is not responding

Start here

Confirm you can switch the plug on and off in Kasa first. If Kasa itself fails, solve that before touching the Alexa integration.

What applies to this exact problem

Check these first

• First check: Confirm you can switch the plug on and off in Kasa first. If Kasa itself fails, solve that before touching the Alexa integration.
• What to do: In Alexa, confirm the TP-Link Kasa skill/account link is current and run device discovery again. Avoid factory-resetting the plug for an Alexa-only failure.
• Done when: The same plug responds in both Kasa and Alexa without creating a duplicate device.

Fix it in this order

1. First check: Confirm you can switch the plug on and off in Kasa first. If Kasa itself fails, solve that before touching the Alexa integration.
2. What to do: In Alexa, confirm the TP-Link Kasa skill/account link is current and run device discovery again. Avoid factory-resetting the plug for an Alexa-only failure.
3. Done when: The same plug responds in both Kasa and Alexa without creating a duplicate device.
4. If it still fails: If Kasa remains healthy but Alexa still fails, unlink/relink the Kasa integration using Amazon/TP-Link guidance and check for duplicate or stale device entries.
5. Confirm you can switch the plug on and off in Kasa first.

Evidence to keep

• LED/error state — keep it with the evidence for “Kasa plug works in the Kasa app but Alexa says it is not responding”.
• Router/network details without passwords — keep it with the evidence for “Kasa plug works in the Kasa app but Alexa says it is not responding”.

Do not make it harder

• Factory-resetting before checking simpler causes For “Kasa plug works in the Kasa app but Alexa says it is not responding”, that can hide whether the underlying issue is actually resolved.
• Posting Wi-Fi passwords or tokens in support screenshots For “Kasa plug works in the Kasa app but Alexa says it is not responding”, that can hide whether the underlying issue is actually resolved.
• Changing multiple router settings at once For “Kasa plug works in the Kasa app but Alexa says it is not responding”, that can hide whether the underlying issue is actually resolved.

How you know it is fixed

• The next action has an owner and a traceable completion record for “Kasa plug works in the Kasa app but Alexa says it is not responding”.
• The official status changes to the expected final state, not merely “case closed” for “Kasa plug works in the Kasa app but Alexa says it is not responding”.

If this still isn't resolved

1. Vendor status/support State the unresolved issue explicitly: “Kasa plug works in the Kasa app but Alexa says it is not responding”.
2. Router/ISP support if the network itself is failing State the unresolved issue explicitly: “Kasa plug works in the Kasa app but Alexa says it is not responding”.
3. Warranty/replacement when hardware diagnostics point to a device fault State the unresolved issue explicitly: “Kasa plug works in the Kasa app but Alexa says it is not responding”.
