Smart homes can be tricky to manage, especially if you've invested in a bunch of different brands. If you have a Google Home, good news: You can now use the Google Assistant to clean up and "sync" any misbehaving devices. Let's say you have some Philips Hue lights in your living room — you set them up and everything works great. A few months later, you buy some extra bulbs for the kitchen, but your Home doesn't seem to recognise them. You could, of course, start poking around the appropriate apps, but now there's a voice command that will do it for you: Sync My Lights.
