openhomedevice

Library to provide an API to an existing openhome device. The device needs to have been discovered first by something like netdisco (https://github.com/home-assistant/netdisco).

The underlying UPnP client library used is https://github.com/StevenLooman/async_upnp_client

• Tested against Linn Products Ltd devices running Davaar 80 (thought expected to work on earlier variants)
• Tested against OpenHome Player devices

Installation

pip install openhomedevice

{
   "status":"update_available",
   "current_software":{
      "version":"4.99.491",
      "topic":"main",
      "channel":"release"

When the system is on the latest firmware:

{
   "status":"on_latest",
   "current_software":{
      "version":"4.100.502",
      "topic":"main",
      "channel":"release"
   }
}

Upgrading Firmware

Use this to check if an update is required and then instruct the device to apply it

    await openhomeDevice.check_latest_firmware()
    await openhomeDevice.update_firmware()

Playing A Track

Use this to play a short audio track, a podcast Uri or radio station Uri. The audio will be played using the radio source of the device. The trackDetails object should be the same as the one described in the TrackInfo section above.

    track_details = {}
    track_details["uri"] = "http://opml.radiotime.com/Tune.ashx?id=s122119"
    track_details["title"] = 'Linn Radio (Eclectic Music)'
    track_details["albumArtwork"] = 'http://cdn-radiotime-logos.tunein.com/s122119q.png'

    openhomeDevice.PlayMedia(track_details)
