When setting up Google Home Broadcast recently, it worked fine from my Android device, but when I tried sending a broadcast from one of the speakers, I got an error reporting that there were no other speakers on the network.
After chatting with Google Support they were a little confused, but after calling back a second time and trying a few things, we arrived at the fix of factory resetting the Google Home Hub and Google Home Mini.
For the Home Hub, press and hold volume up and volume down for 10 seconds to perform a factory reset.
For the Home Mini, press and hold the orange button on the device base for 12 seconds.
After reconfiguring each device, I was able to say “Ok Google, broadcast ‘test message’” and it was broadcast to all other speakers on my network.
It’s a handy feature we’ll be using often – especially when notifying everyone in the house that it’s time to wake up, a meal is ready, it’s time to leave, or even remotely that you’re on you’re way home.
You can even reply to broadcasts making it a handy home intercom feature. To learn more, check out the Google Home Broadcast documentation.
