Thanks for this excellent work, very helpful, all up and running on hassbian 0.60.0, I struggled somewhat with the installation locations filenames but sorted in the end, for those on a learning curve as I am all went well once installed to the directory where you have your .yaml’s for config and so on, a folder created in here for scripts with the file pair_bluetooth.sh and the tts_bluetooth speaker.py also in this directory in these folders for me /home/homeassistant/.homeassistant/custom_components/media_player/ I’m not sure if it helped in my case but also ran the sudo adduser homeassistant pulse-access, ran sudo chmod a+x /home/homeassistant/.homeassistant/scripts/pair_bluetooth.sh, also created a /tmp/tts folder and included this parameter in the config for google tts and tts_bluetooth_speaker in the configuration.yaml as per the guide on HA for tts. I’ve not included any of the device tracker set up for the time being. I also found these useful; https://www.cnet.com/uk/how-to/how-to-setup-bluetooth-on-a-raspberry-pi-3/ and https://www.raspberrypi.org/forums/viewtopic.php?t=53299 for getting the devices paired in the Pi. It’s going to be a bit of a pain identifying when I get to multiple speakers.
I already have a load of notifications from the speaker jack on the Pi (via vlc) that works great and annoys the wife along with Alexa bespoke intents/responses so ill be working on a input_boolean to flick between these speakers and my Bluetooth speaker/s depending where I want the sound. I have speakers all over the house so this Bluetooth is great with the Bluetooth amp they are connected to (turned on via HA and set to Bluetooth via the broadlink IR). WinSCP was great for quick editing. Thanks Again.

[Sunonline (Sun K)]

may I ask regarding the bluetooth. Did you use the default bluetooth from rp3 or external bluetooth and if you use the default bluetooth of rp3, did you also connect the internet via lan or wifi?

For me, it work great but not automatically connected to the bluetooth once restart rp3. and seem I have to bluetoothctl everytime to see the sink_bluetooth speaker to connect.

[dingleydell (dingledell)]

Hi

If I recall I spent quite some time on this same issue but got it to connect permanent in the end, Ill see if I can put a post together with the files I changed, it was in the pulse system and default ones and there was a few others with idle times just to be sure. Mine stays connected for good generally but will reconnect if turned on (either pi or speaker). I have file play audio from the 3.5mm jack on omxplayer and Bluetooth vlc, run from shell_command and tts from this script/post on Bluetooth and tts from 3.5 jack on vlc tts. I’ll put something together and post for the disconnection issue as soon as I can with the ones I altered.

Thanks

hy. i tried the guide for enabling TTS via bluetooth, but no matter what I do, pulseaudio service is still failed. I’m using Hassbian

Hello I am not sure what i am doing wrong i have everything working i believe and my Echo speaker is paired and connected. However i cant get audio playback ive tired volume and pre_silence_duration in the config and did not help. Any ideas? when i grep for bluez i see SUSPENDED… any help guys I would appropriate it ! @pkozul @alandtse

Suspended is normal when not playing. Have you tried running the mplayer command manually? You’ll need to find an actual mp3 on your system.

mplayer -ao pulse::bluez_sink.4C_EF_C0_F1_8C_81.a2dp_sink -quiet -channels 2 -volume 100.0 whatever.mp3

Which should result in this in a succesful run:

di someone already try to get this running with intel NUC ?

[Andrew_Lozoya]

Thanks at this point I’ve abandoned this my TTS Polly service never went through the Bluetooth. Either did the mplayer commands.

[marijngiesen]

What helped me to finally get this working on Raspbian Stretch is this:

1. Make sure your bluetooth device is paired successfully

2. Enable a2dp sink in pulse audio

pactl list cards short
0       alsa_card.platform-soc_audio    module-alsa-card.c
1       bluez_card.xx_xx_xx_xx_xx_xx    module-bluez5-device.c

# Grab the card number and enable a2dp sink
pactl set-card-profile 1 a2dp_sink

3. Set this sink as default

pactl set-default-sink bluez_sink.xx_xx_xx_xx_xx_xx.a2dp_sink

4. Now address the device with the .a2dp_sink suffix in the bluetooth tts script

Hope it helps someone else.

@oakbrad

What I’d really like to do is have all of HA’s TTS go through my Echo Dot and just get all TTS through that speaker. Does anyone know if you can still use Alexa commands if it’s paired as a speaker?

@oakbrad did you ever get this to work?

[moskovskiy82]

Any chances for an update? Seems this component relies on HA but there was a breaking change in 0.76

I’m not sure exactly what you want to do with this but you might want to check out the following and see if it meets your needs:

How is it related?
pkozul wrote a great component that uses Bluetooth speakers for tts. It has nothing to do with alexa.

Read the reply from freekeys. They were asking about tts on echo. I might have misunderstood what you were asking about. If I did then ignore my post.

Hi All,

I am nowhere close to getting the Bluetooth speaker added, I just came close to detecting the Bluetooth device in known devices.yaml. I want to use the bluetooth speaker for google home sdk on hassio.

The instructions provided requires a hassbian os, i am directly running my hassio on the raspberry 3 B+. Any addons that can help me with in setting this up ?
