Google Assistant SDK: gRPC API — “Device SDK”

i believe its the official Google Assistant SDK for Devices.

Specifically: the Python “gRPC” sample implementation (googlesamples.assistant.grpc.pushtotalk).

iv been trying for a few days now to get this to work.

i want to use googles TTS voices to control the mirror
i have the voice its self working but when i try getting the assistant to work i have gotten loads of different errors from tenacity to 9979 error. any suggestions? is google assistant just not worth it?
