title: Controlling frequency of notifications received from device
body: <p>Is there a way to control when and how often push notifications are received from the device?</p>
  <p>I'm sending push notifications from Azure to Windows UWP device.  Notification is sent if temperature reaches a tag value or greater, tags are 0, 10, 20, 30, 40, 50 etc</p>
  <p>So device that subscribes to 20 will receive notification from server when temp is 20 or anything higher than 20.</p>
  <p>However my problem is that the server updates every half hour and so if the temperature on one update is 23 then the next updates always stays above 20, the user keeps receiving push notifications. And its kind of not alerting them to anything new, just keeps sending the same message.</p>
  <p>I want to be able for the user specify the following settings for notifications
  because receiving a notification every half hour can get annoying and bother the user too often.</p>
  <ul>
  <li><p>notify always (already doing this)</p>
  </li>
  <li><p>only notify for the first time you reach temperature 20 or greater</p>
  <p>OR
  notify me only once every 2 hours</p>
  </li>
  <li><p>only notify during these times (9:00AM - 10:00pm) - I think this is easy to do, as I can unsubscribe to the notification I guess with a background task and then subscribe back to it)</p>
  </li>
  </ul>
