🔵 How to Fix: Alexa Not Discovering Devices

Follow these steps in order. Most Amazon users fix the issue by step 3.

• Step 1: First confirm the device works in its own app (Hue, Kasa, LIFX, etc.) before trying Alexa discovery. Alexa cannot discover devices that are offline or not set up.
• Step 2: In the Alexa app go to More → Skills & Games → find the device's skill (e.g., "Philips Hue", "TP-Link Kasa") → tap "Disable" → then "Enable" and re-link your account.
• Step 3: Say "Alexa, discover devices" or go to Devices → + → Add Device → select the type to force a manual discovery scan.
• Step 4: Check that the Alexa device and the smart home device are on the same WiFi network. Alexa cannot discover devices on a guest network or separate VLAN.
• Step 5: Disable IPv6 on your router if devices still won't appear — some routers with IPv6 enabled create duplicate network paths that confuse Alexa's discovery.
• Step 6: For Zigbee devices: only the Amazon Echo (4th gen) has a built-in Zigbee hub. Other Echo models cannot discover Zigbee devices directly — they need a bridge like the Hue Bridge.

Alexa going not discovering devices is one of the most common smart home problems — searched 9,200 times every month. The most frequent causes are WiFi signal strength, cloud server outages on the manufacturer's end, firmware updates applied overnight, or the device losing its IP address after a router restart.

• WiFi signal drop: Smart devices need a minimum -65 dBm signal. Use our WiFi Checker tool to test your signal strength at the device location.
• Cloud outage: Amazon's servers can go down. Check the manufacturer's status page before spending time on local troubleshooting.
• Firmware update: Manufacturers push updates overnight. These sometimes break connectivity temporarily. Wait 24 hours before assuming hardware failure.
• IP address change: If your router restarted, the device may have a new IP. A power cycle of the device usually resolves this automatically.
