# Handle PNPublishResult and PNStatus
def publish_callback(result, status):
if status.is_error():
# Handle error
return
print "I just received a publish callback!"
pubnub.publish().channel('sensor_channel').message({ temp: 400 }).async(publish_callback)

USE CASE

Realtime Updates

Keep everyone, and every device realtime. From mapping, geotracking and dispatch, to broadcasting alerts and up-to-the-millisecond updates, when something happens in the real world, it's reflected in your app.

pubnub.addListener({
status: function(statusEvent) {
if ((statusEvent.category === 'PNNetworkDownCategory') || (statusEvent.category === 'PNNetworkIssuesCategory')) {
// Handle error
return;
}
},
message: function(message) {
console.log('Realtime update!! ', message);
},
presence: function(presenceEvent) {
// handle presence
}
});
console.log('Subscribing..');
pubnub.subscribe({
channels: ['hello_world']
});
