Instructions for the mobile app

The app allows users to create a list of GSM devices with predefined commands. These commands can be sent in the form of an SMS message to the target GSM device and thus control its behaviour, e.g., switch on/off a relay, open/close a gate, or de/activate an alarm.

Duplicate existing GSM device

  1. Click on "three-dot" context menu button of the given device

Note: You can use this function in case you want to add more similar GSM devices to the list. We recommend to add one device with all required commands at first and only then use the duplicate function.

Delete existing GSM device

  1. Click on "three dots" context menu button of the given device
  2. Choose Remove device option

Note: If you accidentally delete a GSM device from the list, you can undo this within next 5 seconds by clicking on Undo button in the bottom pop-up bar.


Delete all existing GSM devices

  1. Click on main menu button (three horizontal lines) in the top left corner of the screen

Drop-call support

Some GSM devices support drop-calls. This comes in handy for basic control, e.g. for switch a GSM relay on/off or open/close entrance gate, because drop-calling is free of charge.

How to make a drop-call:

  1. In the list, tap the device button to open device-specific page.
  2. Click on phone icon to make a call, your default telephone app will pop-up
  3. Make a call

Note: Some GSM devices drop the call automatically, for some the call has to be dropped by user.
