OH3 Echo Dot Play External MP3

1

Hi,
Still playing with Echo Dot integration and was hoping to be able to play my own MP3 files, but looks like only files internal to the Echo Dot/AWS can be played.
Is that correct?

Does NOT work:
BackRoomEchoDot_Speak.sendCommand('<speak><audio src="https://openhab.ext.domain:1999/webres/mp3/test.mp3" /></speak>')

DOES work:
BackRoomEchoDot_Speak.sendCommand('<speak><audio src="soundbank://soundlibrary/home/amzn_sfx_doorbell_chime_01" />There\'s someone at the door.</speak>')

Can anyone confirm/deny this?

Tanks,
Richie

correct, as far as I know it is not possible to play other sounds than the soundbank sounds in TTS/speak commands.

I thought that might be the answer.
Oh well, I can’t use my “funny” MP3s :frowning:

Thanks,

Hi,
Ok, so I’ve made some progress and you CAN play external MP3 files, but there are a few caveats:

  1. the file must be formatted as per Amazon’s details (MP3, 16K sample, 48Kb Bit Rate, Constant Bit Rate
  2. The file must be externally accessible on HTTPS (port 443 only) - my tests with https:domain.com:1999/folder/file.mp3 failed
  3. You can’t have JUST the sound, you have to also include some speech text (this is a bit of a pain, so you can’t have just your mp3)

Thanks,
Richie

Hi,
Ok, slight fudge, but I have got it to work using the following:
BackRoomEchoDot_Speak.sendCommand('<speak><prosody volume='silent'>x</prosody><audio src="https://openhab.ext.domain/webres/mp3/test.mp3" /></speak>').

Using x
It provides something to speak, but wrapped in a silent volume, so it isn’t heard.

Hopefully this will help others.

Thanks,
Richie

Hi, can you explain how you created a trusted SSL certificate for HTTPS?

Hi,
I use nginx as a reverse proxy in front of openhab and you can use something like CertifyTheWeb or winacme to get free SSL certs through LetsEncrypt

Thanks,
Richie
