Symptoms

  • App shows the plug as offline or unreachable
  • Physical button on the plug still works
  • Other smart devices on the same network are fine

Likely causes

  • CommonTemporary Wi-Fi dropBrief network interruptions can leave a device showing offline until it reconnects.
  • PossibleRouter changed settings, name, or passwordAny router configuration change can disconnect previously paired devices.
  • PossiblePlug too far from the router or access pointWeak signal can cause devices to drop offline periodically.
  • PossibleManufacturer server issueA cloud outage can make devices appear offline even though they're connected locally.
  • Less commonPlug needs a factory reset and re-pairOccasionally the device's Wi-Fi settings get corrupted and need to be reset.

What to do

  1. Check whether other smart devices on the same network are also showing offline, which points to a router or internet issue.
  2. Restart your router and wait a few minutes for devices to reconnect.
  3. Move the plug to an outlet closer to the router temporarily to test whether range is the issue.
  4. Check the manufacturer's status page for reported outages.
  5. If only this one plug is affected, unplug it for 30 seconds, plug it back in, and see if it reconnects automatically.
  6. As a last resort, factory reset the plug (usually by holding its button 5–10 seconds) and set it up again from scratch.
