If anyone is interested, I created an squeezebox_alert addon for Hass.io. This was necessary due to shell_commands not getting executed correctly in Hass.io. This addon supports playing mp3 files stored locally on your LMS server and also playing audio generated using the TTS component. See below for instructions to set it up. Note, I have only tested this on Hass.io running on a Pi 3. Note, I used the Samba addon to create the files and sometimes had issues where a “^M” character appeared at the end of each line in the file. I used the SSH addon, edited the file using nano and pasted in the text directly to fix the issue. Reference https://home-assistant.io/developers/hassio/addon_tutorial/ for creating the add-on… it is actually very straight-forward.
-
With Samba addon configured, open HASSIO network share. Create a new folder called “squeezebox_alert” in the addons folder. Create the following 4 files in the squeezebox_alert folder:
Dockerfile
config.json
run.sh
squeezebox_alert.sh
-
Paste the contents below into each of the 4 files.
Dockerfile:
