I’d like to use a D1 mini (connected to an external speaker with a jack cable) as a media player. The whole idea is to use it to read notifications sent from Home Assistant.
The jack cable (mono) is connected to the RX and GND pins:
This where my struggles start.
I found a number of ESPHome components that can probably be used:
Which one would be the correct one to use?
How do I specify which pins to use ?
Thanks in advance for your help.
You will soon find out that esp8266 doesn’t have DAC or I2S.
Get Esp32 (like your title says) and MAX98357A.
There is this project: Turn an ESP8266 WemosD1Mini into an audio notifier for Home Assistant: Play MP3, TTS & RTTL
Thanks @tom_l, this is the post I originally followed. Since I was not comfortable with the idea of uploading a binary I had no view upon, I was looking to achieve the same thing with esphome…

my bad… sorry about that.
Have you built this yet?
I read your comments a couple months ago and decided to do the same thing.
Sonocotta makes several ESP32 boards (and full products - like a wireless streaming amp for existing speakers, if you prefer not to build yourself)

Check out the “Louder” and derivatives. Andriy has a flowchart to help you decide which one you need based on your usage requirements. His ESParagus line are ready built amplifiers.
FYI, I finished building a wireless speaker last week and his ESP32 board made it easy to integrate with Home Assistant. Apologies for the shameless plug, I’m exploring the idea of selling them. 3DAudioSpeakers.com
