Custom Variables

You can create custom variables when you need a suitable variable name for your device mapping configuration. For instance, you could use it when you need a variable for a custom purpose or when you need it your own language.

How to create a new custom variable

1. Go to SiteAdmin > Devices > Variables page.

 

On this page you can see the overview of custom variables.

2. In the last row you can fill the details (Name, Description, Type, Unit) of new variable you are adding.

Type: select DoubleStringBoolean depending on what kind of value will you store into this new variable. Typically:

Double: is for anything that stores a number or "something that could be measured" like any Analog signal (fuel level, temperature, speed, etc).

String: is for anything that stores a string of characters, for example RFID or Ibutton that sends the "driver identification number".

Boolean: is to store a signal that can only handle two states (true/false, 0/1, etc). For example: door open, lights on, SOS, etc.

3. Click the Save button.

The new variable will be available in the Device Mapper in the Vehicle Tracker application for any Device type selected.
