Frequently Asked Questions
Wemo app shows devices but all greyed out — cause?
Greyed-out devices in the Wemo app indicate all devices are offline or the app cannot connect to the cloud. Check your internet connection, then restart all Wemo plugs.
Wemo app worked yesterday and suddenly cannot connect today — cause?
A sudden app connection failure is usually caused by a Wemo server issue, an automatic app update that introduced a bug, or a router firmware update that changed local network settings. Check Wemo server status and restart the router.
Can I control Wemo plugs without the internet?
Wemo plugs support limited local Wi-Fi control without internet on some models. If your phone is connected to the same home Wi-Fi as the plug, the Wemo app may still show and control the device even when internet access is down — this depends on the specific Wemo model.
