New Bang Olufsen Masterlink Gateway / Beolink Gateway integration (MLGW/BLGW)

g.iac · January 3, 2021, 10:41pm

Hi there,
Wanted to share my new Bang & Olufsen Masterlink Gateway / BeoLink Gateway integration. This allows you to fully integrate your B&O audio and TV system with Home Assistant through the Master Link or Beolink Gateways.

Hope you like it!

CMDK · January 13, 2021, 11:21am

I’m impressed!

Great, I’ve been waiting for that for a long time Unfortunately, I already have a problem with the login. If I try to connect to my Beolink Gateway (version 1.5.4.557) via integration, I get the error message “Login failed”.
I’ve tested login on my BLGW via telnet/9000 and MLGW-sequences, that is working fine.
The login from Integration on my Beolink Converter works, but of course it doesn’t know the different devices …
What am I doing wrong? Thanks for any hints …
best regards
Lutz

Thanks for the feedback!
can you post the relevant part of the homassistant log? (need to activate Debug logging)

logger:
  logs:
    custom_components.mlgw: debug

Also would be super helpful if you can post a cut and paste of the Telnet session to the BLGW. It may be that the BLGW has a slightly different login sequence than MLGW.

Hi Giovanni,

after I load your component via configuration.yaml and switched off the authentication for the ML protocol in the BLGW, it works!

I have the following entries in the configuration.yaml:

mlgw:
  host: 192.168.1.210
  username: admin
  password: *******
  use_mllog: true
  default_source: RADIO
  available_sources: 
    - A.MEM
    - CD
    - RADIO
  devices:
    - name: TV Wohnzimmer
    - name: BS Essen
    - name: BS Kueche
    - name: TV Arbeitszimmer
    - name: TV Schlafzimmer
    - name: BS Bad
    - name: BLC ML
    - name: BLC NL
    - name: Moment
    - name: Beosound Bad

Here are the log entries:

The login fails, but the devices are then loaded and can then be controlled via HA.

Excellent!

If you need more information …

The component establishes two connections: the failing one is for the enhanced functionality. Your basic functionality works. Can you please send me a cut and paste of a normal telnet to the blgw?

It may be that the blgw responds differently than the mlgw

Also once you are logged in, try the command:

_MLLOG ONLINE

lutzha · February 10, 2021, 4:58pm

Hi Giovanni

When I send the login request via telnet or nc, I only see in the BLGW log that the connection was accepted.

I have activated “require authentication” in the BLGW for Prot. 9000 and restarted HA.
I see only one login attempt in the logbook of the BLGW:

Feb 10 17:37:31 [debug] server: Processing Integration Protocol login...
Feb 10 17:37:31 [notice] server: Integration Protocol: successful login for admin

Feb 10 17:41:18 [debug] server: Sending feedback for an event over Integration protocol connection
Feb 10 17:47:39 [notice] server: Integration Protocol: Ping received.

In the log of the HA I see two login attempts, the first is due to errors (I think for the enhanced functionality), the second is successful.

And a stupid question:

where I should execute the command ‘_MLLOG ONLINE’ ?

best regards
Lutz

PS:
If you want and if it makes sense, I could give you access to my BLGW, I could release port 9000 via NAT …

g.iac · February 10, 2021, 7:17pm

No need to do the nat.
Just do the following from a command line on your computer:

telnet 192.168.1.210

it should show something like this:

Escape character is Ctrl+[

login:

Write your admin password for the blgw

then at the prompt write _MLLOG ONLINE

please cut and past the entire session

thanks!

Can you also cut and paste the full telnet login sequence? I want to see the prompt for login and the command line prompt. That may be the issue.

HA! Found it. the prompt is different, not MLGW>, but BLGW>

thanks to your debugging, I fixed the code.
Try to re-install from the GitHub source and test it again.

So that is because the authentication with BLGW is not working. Either the password was wrong, or potentially BLGW uses a different type of authentication than MLGW.

Can you please try to do this from your browser:
http://192.168.1.210/mlgwpservices.json

and screen shot the login screen and the output.

Ok, so the file is available. Are you sure that the first time you inserted the correct username and password?

If you are putting in the correct username and password, then the authentication type is wrong.

can you please try this from a command line. If you don’t have the curl command, it can be downloaded for windows here: https://curl.se

curl --anyauth -v http://192.168.1.210/mlgwpservices.json

Yes, I am sure with user and password

Ok that’s helpful. I am on vacation right now but will hopefully get to check this when I am back on the weekend.

Hi @g.iac!

First off… Great project! Nice work!
I have been looking for a solution like this for a long time.

I have found a cheap MLGW and managed to connect to it using just the automatic config. So far so good!

I am able to use the Media Player to control my TV but I haven’t been able to receive anything using mlgw.MLGW_telegram.

Am I missing something in the setup? I see you have a “custom strings: hassio” setup as a device in MLGW. Is that needed for this to work?

Hi Jesper

Cool! thank you!

The mlgw should send a few through MLGW_telegram: source status updates, virtual button presses, and light telegrams only if the b&o device in the room actually supports it.

Did you try to scan for mlgw.ML_telegram ? There is typically a lot more traffic there because that monitors the entire bus, not just the small subset that the MLGW forwards ‘officially’.

The custom strings can be used to make events on the mlgw cause to launch a script on home assistant, using Home assistant’s REST API:

POST /api/services/scene/turn_on HTTP/1.1\0D\0AAuthorization: Bearer XXXX\0D\0AContent-Type: application/json\0D\0AContent-Length: 40\0D\0A\0D\0A{"entity_id": "scene.front_evening_off"}

But it’s a pain to configure. You are better off listening to the ML_telegram events on HA. I’m not using custom strings anymore.
