Hi Hifiberrry Team,
I am trying to add some Home-Automation to HifiBerry OS and wonder what the right method is for controlling volume.
Tried to set volume using:
curl -X POST http://127.0.0.1:80/api/volume -d '{"percent":"-50"}'
But this does not seem to have any effect on Spotify as Source?
Would i need to create my own ALSA Mixer API, or is there a better way?
Thanks,
Tony
It affects all sources as it directly control the ALSA volume control.
However, you're not using the API correctly. If you check the curl output, you should see an error as the API server ins't running on port 80, but 81
Thanks HiFiBerry! I overlooked this (as it was mentioned in the Docs https://github.com/hifiberry/audiocontrol2/blob/master/doc/api.md indeed).
I can control HifiBerry now using Alexa ;) All is working now. Really happy.
Cool, how did you implement the Alexa integration?
Using IFFT webhooks, Docker and NGROK. Alternatively you will be able to use Google also, as long as IFFT is supported.
The idea is that you can add/remove your own using docker-compose
services:
ifft-webhooks:
image: edgecrush3r/ifft-hifiberry
network_mode: bridge
environment:
- "IFFT_PORT=3690"
# CHANGE SERVER_ADDRESS to HifiBerry IP
- "IFFT_VAR_SERVER_ADDRESS=10.0.1.9"
# GENERATE YOUR OWN SHARED_SECRET FOR ADDED SECURITY

I havent done much on the ReadMe. But in generic, you need to edit the docker-compose file, and change your Server_address. Then launch using:
docker-compose up -d
this will also punch a reverse connection using ngrok..
check the logs using
docker logs docker-hifiberry_ifft-webhooks_1
and you will find the available webhooks to use in IFFT
