Symptoms

  • Smart plug won't show up in the app during setup
  • Plug loses connection randomly
  • Plug doesn't respond to app or voice commands

Likely causes

  • CommonWeak Wi-Fi signal at the outlet's locationSmart plugs need a decent signal, and outlets are often in corners or behind furniture with poor coverage.
  • CommonThe plug is on a 5GHz-only network it doesn't supportMany smart plugs only connect to 2.4GHz Wi-Fi, not the 5GHz band.
  • PossibleOutdated app or firmwarePairing issues often clear up after updating the app or plug firmware.
  • PossibleThe outlet itself has no powerWorth ruling out a dead outlet before troubleshooting the smart plug's software.

What to do

  1. Confirm the outlet has power by testing it with another device.
  2. Move the plug closer to the router temporarily to test if signal strength is the issue.
  3. Make sure you're connecting to a 2.4GHz Wi-Fi network, not 5GHz, during setup.
  4. Update the smart home app to the latest version before retrying setup.
  5. Reset the plug to factory settings following the manufacturer's instructions, then pair it again.
  6. Restart your router if multiple smart devices are having trouble connecting.
  7. Contact the manufacturer's support if the plug still won't pair after these steps, since it may be defective.
