push allert to my phone that will ignore silent profile How can I make my phone check my website in a background every 30s and activate voice alert that will ignore silent mode if website says for example '1'? Pushing from server to phone is also acceptable but I guess much more difficult and is susseptable to hangs when conectivity is bad. So far i;ve been using Light Flow Lite and additional gmail account - sending myself any email there triggers alarm.
You could try pushover.net, which provides an easy-to-use API for sending notifications to your Android or iOS device.

It should be very efficient, because it's already using Google Cloud Messaging to deliver your push notifications, thus it should not have any adverse effects on the battery life, unlike your proposed solution of manually doing the polling every 30 s.
