Written initially for use in Home Assistant to drive DLNA DMR-capable devices, but useful for other projects as well.

Usage

See examples/ for examples on how to use async_upnp_client.

upnp-client

A command line interface is provided via the upnp-client script. This script can be used to:

• call an action

• subscribe to services and listen for events

• show UPnP traffic (–debug-traffic) from and to the device

• show pretty printed JSON (–pprint) for human readability

The output of the script is a single line of JSON for each action-call or subscription-event. See the programs help for more information.

An example of calling an action:

$ upnp-client --device http://192.168.178.10:49152/description.xml --pprint call-action RC/GetVolume InstanceID=0 Channel=Master
{
    "timestamp": 1531482271.5603056,
    "service_id": "urn:upnp-org:serviceId:RenderingControl",
    "service_type": "urn:schemas-upnp-org:service:RenderingControl:1",
    "action": "GetVolume",
    "in_parameters": {
        "InstanceID": 0,
        "Channel": "Master"
    },
    "out_parameters": {
        "CurrentVolume": 70
    }
}

An example of subscribing to a service, note that the program stays running until you stop it (ctrl-c):

$ upnp-client --device http://192.168.178.10:49152/description.xml --pprint subscribe --bind 192.168.178.72 RC
{
    "timestamp": 1531482518.3663802,
    "service_id": "urn:upnp-org:serviceId:RenderingControl",
    "service_type": "urn:schemas-upnp-org:service:RenderingControl:1",
    "state_variables": {
        "LastChange": "<Event xmlns=\"urn:schemas-upnp-org:metadata-1-0/AVT_RCS\">\n<InstanceID val=\"0\">\n<Mute channel=\"Master\" val=\"0\"/>\n<Volume channel=\"Master\" val=\"70\"/>\n</InstanceID>\n</Event>\n"
    }
}
{
    "timestamp": 1531482518.366804,
    "service_id": "urn:upnp-org:serviceId:RenderingControl",
    "service_type": "urn:schemas-upnp-org:service:RenderingControl:1",
    "state_variables": {
        "Mute": false,
        "Volume": 70
    }
}
