Recommended server hosting infrastructure for 20 devices - Help

Adams 6 years ago

First let me thank the team at traccar for such a wonderful solution.I have managed to run traccar server on AWS free tier instance just to test and understand the features and configurations of the system.
I have a few questions I would love help with :-
-How do we configure a detach event such that if someone detaches the device we get a notification.
-How do we detect moving devices (devices in motion)
-How do we convert knots to km/h.
-What is the recommended VPS server size for 20 Devices on production.
-What about the recommended Mysql infrastructure for the same number of devices.
-Any other recommendations that can increase the performance of the application.
I will be honest there is the option of paying for support but we are so cash tight currently we can't afford it.
Please Help

-How do we configure a detach event such that if someone detaches the device we get a notification.

  • Partly depends on the trackers you're using, I use Teltonika, which give an "unplug" event for obd devices for example. Other devices I setup a computed attribute which detects the "power" going below 1v:
    `power < 1 ? "powerCut" : null

-How do we detect moving devices (devices in motion)

  • You should be able to use the "notification" deviceMoving for this

-How do we convert knots to km/h.

  • you can set the server level units in settings --> Server --> attributes --> speed unit

Out of interest, where are you based? would you be interested in a shared server or dedicated server on a shared infrastructure?

Thank you for your reply.
I am using chinese made clones,when I click on 'check computed attributes' on the device after pasting the command you have written above I get 'Invalid parameters or constraints violation' is there something am missing .....?
On detecting movement I woud wish to have a notfication on my server so that I could use a different UI to draw movement on map..how can I achieve this...?
About setting speed attributes I have managed to set up...Thank you.
I would be interested in dedicated server on shared infrastructure....I am in Eastern region of Africa.
Thanks.
