New command errors on commands I've relied on

Community Member

Ever since new Google platform rollout, basic commands are no longer working. "Hey Google, turn off all lights" now responds "I need to know which lights" And "Hey Google, play xxx on (the device name) now response "I also need to know which device to use" or "I can't find any devices in the home that can play that". Yet the command will work on other devices in the home. Also, preprogrammed routines are not completed.

I too am having the same issue with all my speaker devices when I try to play music or change volume.  "I also need to know which device to use.  Try saying that again, and include the device's name."


Ditto.  It feels like Google Home devices are breaking...and not just the 3rd party brands like Lenovo.

Hi folks,


@JonSn, @gpoduska, @MartySco, this is not the experience we want you to have, let me help you. A few questions: which Nest speakers are we working with? When did your issue begin? Were there any recent changes made?


It would help a lot if you could do a sequential reboot first:  


  1. Unplug the power cord of your router, followed by your Nest speakers.
  2. Plug them back in after 3 minutes.
  3. Restarting your phone might also help.


If the issue persists, follow the steps below to create a new home structure and move your devices there.


To create a home:


  1. Open the Google Home app.
  2. At the top, tap Add.
  3. Tap Create new home.
  4. Follow the steps.

Note: You can have up to 5 homes in your account.


Move a device to a different home:


Note: Not all devices can be moved to a different home this way. Speakers, displays, and Chromecast can be moved, but Nest Wifi point and Nest Hub Max can't. Some Nest and Wifi devices can't be moved to another home. If you have a device that can't be moved to a different home, you need to factory reset your device and set it up again in a new home.


  1. Open the Google Home app.
  2. Open the home the device is in.
  3. Touch and hold your device's tile.
  4. Tap Settings > Device information > Home.
  5. Tap the home you want to move the device to > Next > Move device.
  6. If asked, tap the room you want to move the device to > Next.

For more information about home structures, see this guide.


Let me know how it goes.
