Yes, you can use IoT Manager.
Install IoT Manager from Google Play, broker settings in app not needed. Go to Statistics and press SEND ID TO EMAIL.
Then use simple OneSingnal REST API for send push notifications to you mobile device (required app installed, app running not needed).
Note: you must always use app_ip=8871958c-5f52-11e5-8f7a-c36f5770ade9, ids from you device(s)
Example (Arduino IDE for ESP8266)
And you can receive push notifications for all you Android devices. Thats all!
