I am using HA to output audio messages, using Google Home units as speakers, at specific times or when an event occurs.
I use:
Text-to-speech (TTS): Say a TTS message with google_translate.
This works fine, but my Google Home Units are often on during the day, playing music (not controlled by HA), at a low level, and the music level is sometimes so low that I may not hear when the HA message is activated/playing.
Is it possible (when the message is about to be played), that via an automation or template, temporarily set the sound level of the Google Home unit to a preset value, play the HA message, and then restore the level to its previous (music)level ??
