ESP Wireless Speaker? Music Streaming

3LECTROSHOCKED · November 21, 2020, 9:36am

Is it possible to create an output component for audio streaming. Connect ESP to a DAC?

I want to have wireless speakers around my house and stream music to them from HA. Is this possible?

How about SPDIF signal? Can an ESP output that or does it require a codec interface?

Appriciate if anyone with more C++ knowledge is interested in looking into this

Squeezelite-esp32 is an audio software suite made to run on espressif’s ESP32 wifi (b/g/n) and bluetooth chipset. It offers the following capabilities

Stream your local music and connect to all major on-line music providers (Spotify, Deezer, Tidal, Qobuz) using Logitech Media Server - a.k.a LMS and enjoy multi-room audio synchronization. LMS can be extended by numerous plugins and can be controlled using a Web browser or dedicated applications (iPhone, Android). It can also send audio to UPnP, Sonos, ChromeCast and AirPlay speakers/devices.
Stream from a Bluetooth device (iPhone, Android)
Stream from an AirPlay controller (iPhone, iTunes …) and enjoy synchronization multiroom as well (although it’s AirPlay 1 only)

Very interesting project, thanks!

But that’s not really what I was thinking of. My idea is to have an output component in the ESPHome framework (like a pwm generator or others). Use that with ESP board to receive stream from Home Assistant (like a cast) and output signal to a DAC. This would be a super efficient and low cost way of having audio nodes around the house for music and notifications (alarm, doorbell). If thats possible anyways with this hardware

Buying a full blown music machine with tons of wifi-features is just too expensive and totally an overkill for just playing a chillout mix in the bathroom etc

Thanks for your answer.

Hum sorry for intrusion but makes me think as a very cool and simple design for doing satellites for voice command system like Rhasspy too

Nobody suggested a full blown music system. An esp32 is cheap and lms is open source.

3LECTROSHOCKED · November 21, 2020, 10:26pm

Didn’t mean to offend anyone, sorry Just that my point was to stream from Home Assistant, not to control a music device with it’s own music source. Example, using new HA media browser as player. Or can this suggested setup act as a speaker node? No airplay or cast is what I am looking for in my scenario I am wondering could there be a native HA to ESPHome audio link? Similar to airplay or cast…

3LECTROSHOCKED · November 21, 2020, 10:33pm

Thanks! That would actually be a cool additional feature. A two way setup. Add: A mic preamp, an analog to digital shield and connect esp. Use that to hear you all around the house and take commands. Or sence people presens via audio level differences. Alexa and siri are not always near us and those hubs are just too expencive to have them everywhere…

Did you find a solution?

nickrout · October 21, 2021, 6:48pm

The solution is in post 2.

kazemab · October 26, 2021, 8:08am

yes, but 3LECTROSHOCKED was looking for some other solution. I just wonder if he/she could find it.

I follow this project for quite some time, but it is WIP:

it seems very interesting
I have ordered some components to play around, but didn’t have the time so far
normally, you can enable snapcast server in HA and stream to these satellite ESP32 speakers around your house

I am looking for the same function in ESPHome and Homeassistant, it will bee nice to bee able to make own small speaker to doorbell, notifycations

**Describe the problem you have/What new integration you would like** An ESPHome component that appears as a Media Player to Home Assistant, and presents whatever controls the ESP has to present. e.g. Media Player/Speakers, which would present on/off and 'Volume' for control by HA. **Please describe your use case for this integration and alternatives you've tried:** In my case, I will have an audio amplifier with its own signal source and attached speakers, but whose volume control is accessible via I2C. So an ESP would make an easy way to control its audio volume via HA. **Additional context** An existing component with very similar functionality is "Monochrome Light", because it offers on/off/dimming functions. If you substitute 'volume' for 'dimming' it's almost the same thing. The main difference is that it should present itself to HA as a 'media player' instead of as a 'light'.

you could…

Use the Media_Player_Template
https://github.com/Sennevds/media_player.template
Post MQTT commands to the ESP32 that would be subscribing to whatever topic you configure
ESP32 MQTT Publish Subscribe with Arduino IDE | Random Nerd Tutorials
Use Phil Schatzmann audio streaming
https://github.com/pschatzmann?tab=stars to play the audio

Turn an ESP8266 WemosD1Mini into an audio notifier for Home Assistant: Play MP3, TTS & RTTL?

magiva · March 6, 2022, 10:06am

nice! so you just need the media player template to make it seemless in home assistant

I have been testing on this for a while.

Home assistant → LMS → Squeezelite-esp32 → Bluetooth Speaker (Echo devices)

You have to set transcoding on LMS before transmitting to ESP because it can handle a specific properties while streaming into Bluetooth Speaker.

More importantly, synchronization is not accounting Bluetooth specific delays. So, having synchronized multi room audio with Bluetooth speakers might be a hard reach.
