Manage Google Nest speaker groups
Nate edited this page Nov 18, 2020 · 9 revisions
This is an app that was created for managing Groups of Google Nest speakers.
Some of its features:
- When playing music on a group, change the volume to
musicVolumeunless the volume has been overridden--in which case, use that. - Switch between a "speaking" volume when not playing music and restore the volume to your prior music volume.
- Adjust the volume based on a day mode and night mode (e.g. once it's sunset, make Assistant talk quieter than during the day).
Hope this helps someone get more familiar with this awesome tool!
