Hello dears,
I have a good project in mind that I want to collect around (12 analog & 2 digital) inputs, and send them to fleet management platform (like wialon) through gps device of course.
Now my questions are:
1- Is there a GPS device model that have up to 12 analog inputs? Or I should use an external adaptor (like arduino kit) to collect all needed analog/digital data and prepare them in one packet each time data will be sent??
2- If using external adaptor, how those packets (say every 5 seconds) should be sent through the GPS device?? Through its serial RS-232 port for example?!
3- Suppose complete data (around 15 sensors/data inputs) were sent every 5 seconds, can I see them all at units monitoring window when I place the mouse on the unit??
4- What is the perfect solution to achieve this goal (of monitoring more than 3000 units, each with 15 sensors) live online in one dash-board? No problem to divide the total number of units into groups of course..

Many thanks for your help.

    Hello Ahmad-Arnous ,

    1. I can't suggest a specific device model as we're developing a software platform, not devices. You may try to ask on the Wialon forum for that: https://forum.wialon.com/viewforum.php?id=18
    2. The way of sending such data is device-specific. Usually, RS-232 port data will be stored in the parameter "payload.hex" or "payload.text" in the flespi devices. In any way, if you receive custom data in any parameter, you will be able to parse it into human-readable parameters using PVM plugins: https://flespi.com/kb/how-to-script-custom-parsing-logic-for-message-payload
    3. flespi is a backend platform, you can use the TrackIt tool ( https://flespi.com/tools/trackit ) to display device positions, or fork and modify it as it's an open-source tool. If you mean Wialon monitoring, please ask the Wialon support team that question.
    4. I'm not sure you will find a ready solution for your goal to name it "perfect". You can set up Wialon for this, or use the flespi platform as a backend, develop a UI dashboard, display all 3000 units on it, and make it the perfect solution ourselves.
