Google will stop supporting Assistant on smartwatches running Wear OS 2 in the near future. "Google Assistant support on this watch is ending soon," reads a message in the latest version of the Wear OS companion app, as spotted by 9to5 Google. "Please upgrade to a newer watch that supports Google Assistant and runs Wear OS 3 or later." The companion app is only needed for devices that use Wear OS 2 or earlier versions of the operating system. There's a dedicated Assistant app for Wear OS 3 devices, such as the Samsung Galaxy Watch 4, Fossil smartwatches and, of course, the Pixel Watch.

Google brought its AI assistant to Android Wear 2.0 last year, and has been adding features like Routines and Custom Device Actions ever since. Now the company is bringing a few new features to Assistant on Wear OS (as it's now called), including contextually aware conversation suggestions, auditory answers to your questions and actions for connected devices. 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.
