Bingo ! Works indeed.
Sorry for such basic question …

Hello - I need some help setting up my Bluetooth speaker
I am on Pi3 model B with openhabian and OH3 installed.
Current setup is I play an mp3 file at specific times of the day based on a rule. I have a speaker set connected to pi through the audio jack. Everything works as expected.

I would love to replace the speaker set with a Bluetooth one I have but I am not sure how to get started.
Good news is when I SSH to my pi and run the below command,

hcitool scan

it returns the MAC address and name of my Bluetooth speaker but I don’t know how to connect to it. Don’t know how to tell openhabian to connect to the speaker and from there how to tell Openhab to output the sound through the speaker
Appreciate the help

ltai0001 · May 15, 2022, 4:39pm

ok made some progress using the bluetoothctl tool. I paired the speaker device successfully. But when I try to connect to it I get a bizarre error. Any advice?

Searching for

at the end led me to

I did not try that one so I can’t say anything about cons if there are any.

ltai0001 · May 17, 2022, 2:40am

ok I installed Pulseaudio and now I have the speaker connected

Final step is which audio sink to use? I wrote a simple rule to play the doorbell.mp3 but I don’t hear anything. when I reconnect my old speakers through the audio jack I can hear so the rule is correct…

ltai0001 · May 17, 2022, 3:09am

I ran the below command

pacmd list-sinks

and I see that my default sink is correctly assigned to my bluetooth speaker yet I cant hear anything

ok more updates on this. I installed mpg123 and tested the doorbell.mp3 running the below command

mpg123 doorbell.mp3

It runs correctly and I can hear the sound through the blouetooth speaker.
Now the question is how do I select this default sink in Openhab. See rule below - but I still can’t hear the doorbell

Wolfgang_S · May 17, 2022, 6:20am

I assume that you require the pulse audio binding for this to select the sink from within the openhab UI.
Alternatively you could use executeCommandLine to run your command line to play the sound.

ltai0001 · May 17, 2022, 7:39pm

@Wolfgang_S thank you for your feedback. I will start with the command line because I know that the below one works when I ssh to my system. I can hear the sound.

mpg123 -f 2000 /etc/openhab/sounds/doorbell.mp3

So I tried to recreate through a rule and I installed the Exec binding (screenshot below for the “Thing”, “Channel”, “Item”, and “Rule”. I would love the leverage the interface as much as possible. When I run the rule no sound - I am close but something is still off. BTW the log doesn’t show any errors. Item is switching state as expected it just the sound isnt coming through…

ltai0001 · May 18, 2022, 12:02am

Ok more updates on this never ending quest for the answer
when I run this command I hear sound

openhabian@openhabian:$ mpg123 -f 2000 /etc/openhab/sounds/doorbell.mp3

But, when I run this command I don’t hear anything and no error is given meaning the group openhab does have read write access to the mp3 file

openhabian@openhabian:$ sudo -u openhab mpg123 -f 2000 /etc/openhab/sounds/doorbell.mp3

According to this page - its the openhab user that needs to run the command so how do I give the user access to run the mpg123 command?

Wolfgang_S · May 20, 2022, 8:31pm

where is mpg123 located ? Is it located in standard system bin directory ?
you may try to add the path in front of mpg123
is your command whitelisted ?
mpg123 has it’s r and x bit set so that openhab can read and execute the file ?
same applies for doorbell.mp3 and path towards it
check the groups the user openhab ( id openhab ) belongs to and the user openhabian ( idopenhabian ) belongs to
