Hi on my old raspberry pi 3b with raspbian stretch i installed the old google assistant sdk with :

  1. http://wiki.seeedstudio.com/ReSpeaker_2_Mics_Pi_HAT/
  2. <LINK_TEXT text=“https://developers.google.com/assistant … ry/python/”>https://developers.google.com/assistant/sdk/guides/library/python/</LINK_TEXT>



    I started the google assistant with the google-assistant-demo script.



    But the old google assistant library is depreciated so i installed a fresh version on my rpi 3b.



    I cleaned my rpi and installed:
  3. the latest image buster from raspberry pi org - and
  4. i followed the latest google assistant procedure <LINK_TEXT text=“https://developers.google.com/assistant … ce/python/”>https://developers.google.com/assistant/sdk/guides/service/python/</LINK_TEXT>



    what i missed after installation is my the google-assistant-demo script.

    In my previous/old configuration i had the following bash script /home/pi/google-assistant.sh with



    #!/bin/bash

    source /home/pi/env/bin/activate

    /home/pi/env/bin/google-assistant-demo



    and a file /etc/systemd/system/google-assistant.service with:



    [Unit]

    Description=Google Assistant



    [Service]

    ExecStart=/bin/bash -c ‘/home/pi/google-assistant.sh’

    Restart=always

    User=pi



    [Install]

    WantedBy=multi-user.target

    i installed the service with sudo systemctl enable google-assistant.service.



    i could start and stop this google service



    questions:
  5. How can i start the latest google assistant sdk as a service and put it on or off ?
  6. how do i install my ReSpeaker_2_Mics_Pi_HAT on the latest software Buster / google assistant service?
