howto setup a virtual media renderer?

[sajov]

Hi, impressive work, Thanks!

I have a problem of understanding. I would like to apply loadUri to a specific device. LoadUri is only available for virtual renderers. How can I make a media renderer a virtual media renderer with raumkernel?

A virtual renderer is a device which will be created by raumfeld if you create a zone out of a room So you have to create a zone out of a room (or find the zone with a room-udn if already there) to get a virtual media renderer.

eg.:

this.managerDisposer.zoneManager.connectRoomToZone(_roomUdn, "", true).then(function(_data){
                _resolve(_data);
            }).catch(function(_data){
                _reject(_data);
            });

Above code will create a new zone for the room with the given room-udn. And so it will create a virtual media renderer too

thank you for the answer! I want to address a specific speaker, regardless of whether it is assigned to a room. To understand, I want to send an acoustic feedback from a smart home system to a speaker. In the logs my devices look like this, I see media renderer, virtual media renderer and media server. Test to connectRoomToZone gives me following error:

I am lost in Glossar

I want to address a specific speaker, regardless of whether it is assigned to a room.

The Raumfeld system itself can not play anything if the speaker is not attached to a room and the room is not attached to a zone. The times the Raumfeld system was able to do that are long time ago :-(

Test to connectRoomToZone gives me following error:

what's your code?

The code looks now this, on systemReady i try to get/create a virtual reanderer

    const raumkernel = new RaumkernelLib.Raumkernel();
    raumkernel.settings.raumfeldHost = '192.168.0.20';
    raumkernel.settings.uriMetaDataTemplateFile = 'src/services/raumfeld/setUriMetadata.template';
    raumkernel.createLogger();
    raumkernel.on('systemReady', function (_ready: any) {
      raumkernel.logInfo('System ready: ' + _ready);
      raumkernel.managerDisposer.zoneManager.connectRoomToZone('uuid:5208bce6-a82b-40a2-a85f-722ef24af11b','', false).then(function (data: any) {
        console.log({data});
      }).catch(function (error: any) {
        console.log({error});
      });
    });
    raumkernel.init();

log shows:

I don't have rooms. The Raumfeld mobile app -> settings -> devices, shows for each speaker, the speaker name also as room name. :-(

@sajov Can you try to call connectRoomToZone with the third parameter as 'true' ? This will ensure that the promise which will be returned will be fulfilled when the room was connected to the zone or a new zone was created. With the parameter set to false the promise will return immediately, it does not wait for the zone to be created raumkernel.managerDisposer.zoneManager.connectRoomToZone('uuid:5208bce6-a82b-40a2-a85f-722ef24af11b','', true)
