Hi everybody,
I am trying to get a dfplayer module to work with ESPHome. It seems to be connected and programmed correctly (for example, I get log output like TF Card available when I insert one), but I cannot get it to play any audio.
However, when I manually initiate audio playback (by connecting GND to the dfplayer's IO_2 or IO_1), it does play. So this makes me think that
- the speaker is connected correctly
- the size and file system of my SD card is correct
- the MP3 files have the appropriate encoding
It is connected like this (Wemos D1 Mini powered via USB, but also tried an external power source, no difference):
| Wemos D1 Mini | dfplayer |
|---|---|
| 3V3 | VCC |
| GND | GND |
| D4 | TX |
| D5 | RX |
The relevant part of my dfplayer.yaml is at the bottom. The defined logger.log message will be displayed when I manually initiate audio playback, so I assume the ESPHome does register things correctly as well. Only initiating playback won’t work. I tried it like this
service: esphome.tester_dfplayer_play
data:
file: 1 #or file: 001
# ==> [13:24:21][D][dfplayer:032]: Send Command 0x3 arg 0x01
service: esphome.tester_dfplayer_play_folder
data:
folder: 1 #or 01 or 001
file: 1 # or 01 or 001
# ==> [13:23:59][D][dfplayer:032]: Send Command 0xf arg 0x101
I tried the esphome.tester_dfplayer_next service as well after manually initiating playback. This does not work, either (even though there are multiple MP3 files on the SD card).
So while I cannot control the dfplayer module successfully via ESPHome, I can communicate with it via UART, as it will display message when inserting/taking out an SD card and when playback has stopped after manually initiating it.
Only using Home Assistant to play/stop/change tracks does not work. Can you please help me fix this problem? Thank you in advance for your ideas
