Google Cast Group volume setting

Configuration
1

Hi all,

I have different gmini grouped in a “broadcast” group. Sporadically I use some of them to stream music so It may happens that they have very different volumes.

That’s why I have an automation that set volume to zero during the night. But I noticed (via automation or via ghome app) that if I change volume to the group it does not apply it to every gmini but it reduces volumes of a certain percentage based on the starting volume of each device.

Can some one please suggest me a way to avoid it?

Thank you in advance

I’m not sure if you have solved your problem, and not 100% sure i understand your problem either.

For volume sync i use: https://github.com/allanpersson/home-assistant-config/tree/master/config/automations/areas/helehuset/media_players_volume_sync

A solution if your volume goes down could be if you have nightmode activated in your Google Home app for the device, which lower the volume and light. See https://support.google.com/googlenest/answer/7426381?hl=en

Uhm let me understand:

those automation are triggered by every media player you have and as action they change volume to every other media player accordly, right?

Because maybe this will be a good solution to me!

Yes, if:

Google home volume is raised to a new volume level, the other ones will sync to the same volume level. The delay is there to avoid volume changes getting stuck in a loop.

Note it’s only triggering when you change the volume, so if entity1 is at 10% and entity2 is at 20% when you start the media it will stay there until one of your devices changes to a new volume level.
