You can already tell Google Assistant to control your smart home devices like, say, setting the temperature of your LG fridge. Now this feature is coming to your Wear OS device, too, which means you'll get to talk to you wrist to set your thermostat or turn on the Hue lights in your bedroom. Hearing the answer to a question via your watch speaker or Bluetooth-connected headphones can be more convenient than having to lift your wrist to see a visual response, too, and pre-set response suggestions will offer up things you might not think of when asking Assistant for the weather, for example. All these features will roll out to Wear OS devices over the next several days, so keep an eye out for an update.
