How to get android state information remotely?

Question

Android

I have a smartphone that I use as a modem, I would like to be able to remotely control it and be able to receive information about the level of charging, on / off distribution, mobile Internet,
etc. distribution. But here is the problem with feedback. You can't call or send SMS from the installed SIM card.
I know that there are all sorts of Android Monitor or AirDroid, but they are too heavy for smart and they require constant work, which is not very good. I would like to come up with my own scooter, simple as a stick and performing the necessary tasks.
Does anyone have experience or ideas? I would be grateful for any lead.

Answer 1

In principle, you can write your application using Android Studio and interact with Heroku or Aamazon AWS to send requests.
In fact, there will be an application installed on a smartphone / modem from which you need to take information and an application is installed on a smartphone to which information will come.
Scheme: go to your application on a personal android and request the necessary information about the modem system --> then the request from the application goes to the Heroku or AWS cloud, then it is sent to the smartphone / modem and takes the necessary information. --> further the answer passes a chain on the contrary.
But this implementation is more suitable for larger projects.
You can make remote access to the terminal via SSH and optionally turn it into a VPN.
