Get your missing Smart Life/Tuya lights and plugs back inside Google Home without factory resets.

This is for Google Home users whose devices suddenly disappeared after a sync glitch.

Time required: about 2–5 minutes.

Quick Answer

If your Smart Life devices vanish from Google Home, remove the Smart Life link in Works with Google, then link it again. Google Home usually re-imports your devices immediately, and you can reassign rooms in under 5 minutes.

What You Need (Prerequisites)

The Single Trick: Re-Link Smart Life in Google Home

  1. Open linked services in Google Home.
    Open Google Home → tap your profile photo (top-right) → Assistant settings → Home control (or Works with Google, depending on app version).
    Expected result: You can see Smart Life/Tuya listed under linked services.
  2. Unlink Smart Life.
    Tap Smart Life (or Tuya Smart) → Unlink account / Remove and confirm.
    Expected result: Connected Smart Life devices temporarily disappear from Google Home.
  3. Link Smart Life again.
    Tap + Add → Set up device → Works with Google → search for Smart Life → sign in and authorize.
    Expected result: Devices re-import into Google Home and can be assigned to rooms again.
  4. Run a quick voice test.
    Say: “Hey Google, turn on kitchen light.”
    Expected result: Device responds normally and routines work again.

Expected Result Checks

  • Missing devices are visible again in the Devices tab
  • Each device appears in the correct room (or can be reassigned)
  • Voice commands and routines run without “device unavailable” errors

Common Mistakes

  • Unlinking the wrong service: Some users have both Smart Life and Tuya linked—remove and re-add the one your devices actually use.
  • Skipping Smart Life verification first: If devices are offline in Smart Life, Google Home cannot import them.
  • Not finishing authorization: Closing the browser too early can leave the service half-linked.

Quick Troubleshooting

  • Smart Life does not appear in Works with Google: Update Google Home and reopen the app. Official setup reference: Set up and manage Works with Google devices.
  • Devices still missing after re-link: Confirm each device is online in Smart Life, then reboot your router and one affected device.
  • Android app acting stuck: Clear Google Home app cache, then retry. Steps: Clear an app’s cache and data on Android.
  • Still broken after all steps: Remove and re-add only the failing devices inside Smart Life, then sync again.

Why This Works

When account linking tokens desync, Google Home may keep stale mappings and show devices as missing. Re-linking forces a fresh authorization and new device pull from Smart Life.
