Is here anyone using Volumio?

I guess the autonomous change of the hostname is issued by the discovery handler.

patrickse/org.openhab.binding.volumio2/blob/cf791b60103bdc746bb4976872f9a3a5c721d114/src/main/java/org/openhab/binding/volumio2/internal/discovery/Volumio2DiscoveryParticipant.java#L61


DiscoveryResult discoveryResult = null;
ThingUID thingUID = null;


log.debug("Service Device: {}", service);


thingUID = getThingUID(service);


log.debug("Thing UID: {}", thingUID);


if (thingUID != null) {
    properties.put("hostname", service.getServer());
    properties.put("port", service.getPort());
    properties.put("protocol", "http");
    discoveryResult = DiscoveryResultBuilder.create(thingUID).withProperties(properties).withLabel(volumioName)
            .build();


    log.debug("DiscoveryResult: {}", discoveryResult);
}


return discoveryResult;

At this point I retrieve the server name from the mdns name and return the result to openhab. Because the uuid is unique, I guess openhab relates the discovered hostname to the already defined thing and overwrites the property.

That´s just a gues… as I am still struggling with my test environment…
