2 things hopefully able to be fixed:
Listening to sonos with higher volume on the day and then asking with Google Assistant later, e.g. switch the lights of. Is very annoying. As Sonos repeats with the last volume set very loud.
Either a separate volume for voice assistant or a scheduled maximum volume set would be important.
IFTT does not work as well because I can only set to a specific volume what could potentially increase the volume while watching TV.
The second wish would be scheduled activation of the night mode.
