Hey everyone, I’ve been really curious about integrating the DFPlayer Mini MP3 player into my smart home setup. I’ve seen some great examples online, but I wanted to share my own journey and see if others have tackled this too!
The Setup
I’ve got an ESP32-cam based doorbell system that I’d love to add some voice notifications to. The idea is to have pre-recorded messages like “Just a moment. I’ll be right there.” play when someone rings the doorbell. It’s a small touch that could make things much smoother for visitors.
The Challenge
I’ve been exploring how to control the DFPlayer Mini using ESPHome. From what I gather, it’s possible to use the UART bus or a custom UART device with one of the Arduino libraries like DFPlayerMini Fast. I’ve been tinkering with the code, but I’m not entirely sure if I’m on the right track. Here’s a snippet of what I’ve tried so far:
python
// Play track 0013.mp3 of Dfplayer microSD
class DFPlayerMini {
public:
DFPlayerMini(SoftwareSerial *swSerial);
void begin();
void play(uint16_t track);
void next();
void previous();
void volume(uint8_t vol);
void eq(uint8_t eq);

void LedEffectBlinkSlow(uint8_t LedEffectBlinkSlow);
void LedEffectBlinkMedium(uint8_t LedEffectBlinkMedium);
void LedEffectBlinkCustom(uint8_t LedEffectBlinkCustom);
void LedEffectBlinkStop(uint8_t LedEffectBlinkStop);
void LedEffectBlinkResume(uint8_t LedEffectBlinkResume);

}
The Goal
I’d love to know if anyone else has successfully integrated the DFPlayer Mini with ESPHome. Any tips or tricks would be greatly appreciated! I’m also curious if there’s a more streamlined way to handle the MP3 playback without relying too heavily on custom code.
Looking Forward
I’m really hopeful that this project will come together. It’s a fun way to add a personal touch to the doorbell system, and I can’t wait to see how it turns out. If anyone has experience with this or similar setups, please share your insights!
Cheers,
