Google Home Extension for Visual Studio Code is designed and created for Google Home Platform developers. This extension gives you access to Google Assistant Simulator, Cloud Logging, and other tools to simplify your smart home development process.
Google Home Extension Features
Google Assistant Simulator
To test whether your smart home devices work properly with the Google Home ecosystem, you can interact with Assistant Simulator at any time without leaving VS Code.
Similar to the existing Simulator provided in the Actions Console, Assistant Simulator enables you to easily control your devices by typing your queries, for example, "Turn on the light." Inside VS Code, Assistant Simulator responds back with text messages based on your commands, for example, "Alright, turning on the light." See Use Google Assistant Simulator for more details.
To test your Google Home integration like an automaton, you can send batch utterances to Google Assistant Simulator by running an utterance script. See Run Batch Utterances for more details.
Cloud Logging provides debugging information and key metrics to give you insights into your Action's usage. To simplify development, the Google Home Extension shows real-time Google Cloud Logging messages right next to your code during troubleshooting. See View Cloud Logging for more details.
Home Graph Viewer
Home Graph Viewer is now available directly in the Google Home Extension so that you can verify the state of the device in your Home Graph inside VS Code. See View Home Graph and Run Tests for more details.
