Yeah. I am super excited too.
The description says…
Home Assistant 0.35 will include text to speech support that can play on the Google Home, Sonos or any other media player that supports playing from a remote URL.
I’m wondering am I able to DIY it using a Raspberry Pi attached to a speaker?
From the next release you can control vlc from ha: https://github.com/home-assistant/home-assistant/pull/4800
Then you can play the file from your Raspberry Pi
Can you control a remote VLC running another machine? I have one Raspberry 3 Running HA, and another in the kitchen that handle my google calendars for the family and weather radar. I already have VLC running on it and accessible as a speaker from smartthings via VLC Thing. VLC runs on port 8080. I would be nice if I could send TTS to it from HA
Maybe in the future something like this
media_player:
- platform: vlc
name: test
host: 192.168.7.xx << host of device running vlc
port: 3030
password: vlc password
if you can log into http:\192.168.7.xx:3030 with the password it should work.
