I get the best result by adjusting the volume of the other Sonos in the same group to the changed Sonos with a delay from 1 to 3 seconds.
The easiest way > You need for each speaker one Flow like this:
MY FLOW S1
When
Volume S1 changend
And
Logic-Card with cointained a + (to make sure that the speaker is in a group)
Then
Deaktivate MY FLOW S2
Deaktivate MY FLOW S3
Deaktivate MY FLOW S4
Change Volume S2 to Volume S1 delay 1 seconds
Change Volume S3 to Volume S1 delay 1 seconds
Change Volume S4 to Volume S1 delay 1 seconds
Activate MY FLOW S2 delay 2 seconds
Activate MY FLOW S3 delay 2 seconds
Activate MY FLOW S4 delay 3 seconds
MY FLOW S2
When
Volume S2 changend
And
Logic-Card with cointained a + (to make sure that the speaker is in a group)
Then
Deaktivate MY FLOW S1
Deaktivate MY FLOW S3
Deaktivate MY FLOW S4
Change Volume S1 to Volume S2 delay 1 seconds
Change Volume S3 to Volume S2 delay 1 seconds
Change Volume S4 to Volume S2 delay 1 seconds
Activate MY FLOW S1 delay 2 seconds
Activate MY FLOW S3 delay 2 seconds
Activate MY FLOW S4 delay 3 seconds
and so on for the other speakers. You need activation/deactivation otherwise the Flows run into a loop.
