Wemo smart plugs and switches are known for occasional connectivity issues. This guide helps resolve common problems with Wemo devices.
Device Shows as "Not Detected"
If the Wemo app can't find your device:
- Same network: Ensure your phone and Wemo are on the same 2.4GHz WiFi network
- Restart device: Unplug the Wemo for 30 seconds, then plug back in
- Router reboot: Sometimes a router restart resolves discovery issues
- Firmware update: Check for and install any pending firmware updates
- Re-pair: Factory reset (hold button 5 seconds until light blinks orange) and set up again
Device Goes Offline Randomly
Wemo devices dropping offline frequently:
- WiFi band: Wemo devices only work on 2.4GHz - disable or separate 5GHz if using same SSID
- DHCP reservation: Set a static IP for each Wemo device in your router
- UPnP: Enable UPnP in router settings if disabled
- Firmware bugs: Some firmware versions have stability issues - check Wemo community for known problems
- Power cycling schedule: Some users set up weekly smart power strip reboots to maintain stability
HomeKit Issues
For HomeKit-enabled Wemo devices:
- HomeKit code: The setup code is on the device or quick start guide
- Already paired: If previously paired, you may need to reset and re-add to HomeKit
- Home Hub: Ensure you have an Apple TV, HomePod, or iPad as a home hub for remote access
- iCloud sync: HomeKit issues can stem from iCloud - sign out and back in
Matter Wemo Devices
For newer Matter-enabled Wemo products:
- Thread border router: Matter over Thread requires a border router (HomePod Mini, Apple TV 4K, etc.)
- Commission via app: Use the Home app or Wemo app to commission the device
- QR code: The Matter QR code is on the device or packaging
