On our android phones, we hold the home button to bring up Google Assistant.
Then we tell it to “turn off [chromecast name]”, by voice command.
Back in the day, we used the Google Home Mini to perform that function. However, over time we started feeling uneasy about its potential to breach our privacy. So we parted ways.
