Symptoms
- Multiple devices show as offline or unresponsive
- Commands from the app don't take effect
- Physical control of devices, like a light switch, still works
Likely causes
- CommonInternet or Wi-Fi outageCloud-connected devices need internet access to respond to app commands.
- CommonHub or bridge device is offlineMany devices route through a central hub that, if down, takes everything with it.
- PossibleApp or manufacturer server issueA widespread outage on the manufacturer's servers can affect all connected devices at once.
- PossibleRouter needing a restartOverloaded or glitching routers can silently drop many devices.
- PossiblePhone's own connectivity issueIf your phone itself has no signal or Wi-Fi, the app can't reach anything.
What to do
- Check your phone's own internet connection first by trying a website or another app.
- Check whether the hub or bridge device (if you have one) shows as online.
- Restart your router and modem.
- Check the manufacturer's status page or social media for a reported service outage.
- Try controlling one device physically, like a light switch, to confirm the device itself is fine and it's a connectivity issue.
- If only the app is affected, force-quit and reopen it, or reinstall it if problems continue.
Tools and parts
- Smartphone
When to call a pro
Contact your internet provider if the outage is network-wide, or the device manufacturer if only their specific app and devices are affected.
