AaronDavidSchneider/SonosAlarm v1.1.3

Fix for advanced-use

on GitHub

You can also use configuration.yaml configurations to specify your specific network requirements.

Here is an example configuration:

sonos_alarm:
   switch:
      hosts:
        - 192.168.178.22
        - 192.168.178.29
        - 192.168.178.24

For more information see: https://www.home-assistant.io/integrations/sonos/#advanced-use
(same idea, just use sonos_alarm and switch instead of sonos and media_player)

Many thanks for bringing this up @Schmandre!!!
