title: Can't get vpn_url from Netatmo Welcome camera
body: <p>I'm developing an app that shows the live video from a Welcome camera. The problem is that I can't get the vpn_url from my camera. When I try to get this info from the gethomedata api call I get the following object within cameras json array.</p>
  
  <pre><code>[ { id: 'XX:XX:XX:XX:XX:XX',
      type: 'NACamera',
      status: 'on',
      sd_status: 'on',
      alim_status: 'on',
      name: 'MyFirstCamera' } ]
  </code></pre>
