Google Home Glitch Causes Room Commands to Control All Lights in the House

Google Home users are encountering a serious bug: when issuing room-specific voice commands like “turn off the bedroom lights,” the system is activating or deactivating every light across the entire home. This issue has appeared across multiple devices—including Google Nest speakers and smart hubs—and shows up even when lights are correctly grouped within the app.

Reports from Reddit and Google Nest community forums describe situations where a simple command such as “turn on the barn” instead affects unrelated devices—such as ceiling fans—across different rooms or even off-site locations. Rebooting, performing factory resets, and relinking devices have failed to resolve the glitch. It appears that the voice assistant is ignoring room assignments and interpreting commands globally instead of locally.

This malfunction isn’t isolated—users have noticed a general decline in Google Home’s reliability. Frequently, it misinterprets commands, doesn’t execute routines properly, or performs incorrect actions. Recent app and firmware updates meant to fix issues have instead introduced new problems, including this global light control bug. Reports also mention smart bulbs from brands like Tapo and Smart Life flickering offline and playback routines behaving erratically.

Multiple homeowners affected describe significant inconvenience. Some woke family members at odd hours when every light in the house suddenly flipped on. Others experienced headaches managing automations remotely, as the system no longer respects room-level commands. This is more than a minor nuisance—it disrupts daily routines and undermines trust in the smart home setup.

Common troubleshooting steps—rebooting devices, organizing lights into well-defined room groups, and relinking the Home app—haven’t helped. Some users suggest naming and grouping devices more distinctly or using local device routines to intercept faulty voice commands. However, these are partial workarounds, not permanent solutions.

Currently, Google has not publicly acknowledged the issue or provided a timeline for a fix. The lack of response leaves many frustrated and wondering whether to switch to alternative ecosystems or scale back on voice controls until stability returns.

For now, cautious users may want to temporarily disable voice automation for lighting or rely on manual controls and device-specific routines. Monitoring community forums closely will be the best way to track any emerging fixes. As is, the bug highlights the fragility of voice-driven smart home systems when software changes outpace consistent performance.
