gassist_text

A Python library for interacting with Google Assistant API via text.

Credits

Uses https://pypi.org/project/google-assistant-grpc/. See instructions there how to get credentials.json.

Code is essentially a copy of https://github.com/googlesamples/assistant-sdk-python/blob/master/google-assistant-sdk/googlesamples/assistant/grpc/textinput.py wrapped in a package.

Example

import json
import google.oauth2.credentials
with open('/path/to/credentials.json', 'r') as f:
    credentials = google.oauth2.credentials.Credentials(token=None, **json.load(f))

from gassist_text import TextAssistant
with TextAssistant(credentials) as assistant:
    print(assistant.assist('tell me a joke')[0])
    print(assistant.assist('another one')[0])

Limitations/Known issues

If you see the issued commands in My Google Activity the library is working fine. If the commands don't have the expected outcome, don't open an issue in this repository. You should instead report the issue directly to Google here. Examples of known Google Assistant API issues:

• Broadcast commands don't work unless speakers and device that runs this library are in the same network and IPv6 is disabled in the router
• Most queries for media controls don't work
  • not working: e.g. play music on kitchen speaker, stop kitchen speaker
  • working: e.g. play news on kitchen speaker, play rain sounds on bedroom speaker
• Routines don't work
• Commands that need to verify your identity through voice match don't work

To get personal results working you need to create an OAuth client ID of Desktop app, see step by step instructions here.
