Your app works. The lights work manually. But voice control is dead.
This failure happens in the integration layer, not the lights themselves.
Let’s fix it.
Why This Happens
- Cloud service desync
- Account reauthentication needed
- Skill or integration disabled
- Device name conflicts
- Network identity changes
Common Mistakes
- Renaming devices without resync
- Using duplicate names
- Ignoring cloud service outages
Step-by-Step Fix
- Check cloud service status
- Disable and re-enable skill
- Re-link account
- Re-discover devices
- Reboot hub and router
When to Upgrade Hardware
- Old hubs with slow cloud sync
- Unsupported brands
- Cheap bulbs with flaky firmware
Checklist
- [ ] Skill enabled
- [ ] Account linked
- [ ] Device names unique
- [ ] Hub rebooted
FAQ
Why did it stop overnight? Token expiration or cloud update.
Why does one light work and not another? Sync or naming issues.
Final Thoughts
Voice control is only as reliable as the services connecting everything. Refresh the links and control returns.
