Hello,
I’m very new to writing addons for home assistant and am running into some difficulties.
There is bound to be a lot I don’t understand, any help would be great.
Long term goal
Setup my raspberry pi 4 as both a hassio server and a bluetooth speaker so I can connect my phone to the raspberry pi 4 via the built in bluetooth and play music from my phone to a set of connected speakers on the raspberry pi.
I figured the way to get both of these working on the one device is to get the bluetooth speaker part setup as a hassio plugin as I already have hassio setup.
Short term goal
Play local audio generated from within a hassio addon to speakers connected to the raspberry pi 4 running hassio.
To do this, I’m starting with gTTS to generate a sound clip saying “hello”.
What I’ve got so far (for the short term goal)
I started by following the addon tutorial with a few minor additions, the main one being to add the "audio": true config which I read from here.
I ended up with my addon installed and running, here are the 3 files that make it up:
Dockerfile
ARG BUILD_FROM
FROM $BUILD_FROM
ENV LANG C.UTF-8
# Copy data for add-on
COPY run.sh /
# Install requirements for add-on
RUN apk add --no-cache python3 mpg123 alsa-plugins-pulse
RUN pip3 install gTTS
WORKDIR /data
RUN chmod a+x /run.sh
CMD [ "/run.sh" ]
config.json
{
"name": "Hello world",
"version": "12",
"slug": "hello_world",
"description": "Says hello to the world, literally.",
"panel_icon": "mdi:bluetooth",
"arch": ["armhf", "armv7", "aarch64", "amd64", "i386"],
"startup": "before",
"boot": "auto",
"options": {},
"schema": {},
"audio": true
}
run.sh
#!/usr/bin/with-contenv bashio
echo "Saying hello"
gtts-cli "Hello" | mpg123 -
echo "All done"
The result
The script executes ok but does not play any sound.
Here is the output from the log tab of the addon page:
