Goal Track car real-time. Integrate into HomeSeer and create location based services.
UPDATE: a new version (0.2) of the tracking script for Homeseer has been posted below.

HOW?

• Tracking device
• Xexun TK102/103 tracking device (see “Tracker” section below)
• Option 1: Use script with an existing tracking service (see GPS-TRACE.COM example below)
  (I used option 1)
• Option 2: Create Software that acts as a ‘server’ for your tracking device
  • TCP client sample
  • TCP listener sample
  • Sockets example
  • Sockets example 2

Using GPS-TRACE.COM?

If you’re using the gps-trace.com service please look at the following script. It allows you to grab your location from the website and put it in HomeSeer devices.
How?

• Create an account on www.gps-trace.com
• Make sure your tracker works with this service.
• Download my gps-trace grabber script (New version 0.2!)
• Copy script to your HomeSeer\Script directory
• Create HomeSeer devices (see instructions in script)
• Modify parameters in script (see instructions in script: easy!)
• Create event that runs the script every x minutes.

Information

• NMEA data send by tracker uses this format:
• $GPRMC,aaaaaa,b,cccc.cc,d,eeeee.ee,f,ggg.g,hhh.h,jjjjjj,kkk.k,l*mm

Where

• aaaaaa is the time of the fix UTC in hhmmss format
• b is the validity of the fix (“A” = valid, “V” = invalid)
• cccc.cc is the current latitude in ddmm.mm format
• d is the latitude hemisphere (“N” = northern, “S” = southern)
• eeeee.ee is the current longitude in dddmm.mm format
• f is the longitude hemisphere (“E” = eastern, “W” = western)
• ggg.g is the speed in knots
• hhh.h is the true course in degrees
• jjjjjj is the date in DDMMYY format
• kkk.k is the magnetic variation in degrees
• l is the direction of magnetic variation (“E” = east, “W” = west)
• mm is the checksum

Tracker

One of the most popular trackers are the Xexun 102 and 103 trackers. There’s imitation devices being sold so be careful. I have never seen a product where the documentation is so bad, the amount of documentation versions is so huge (each saying something different) and where there is NOT 1 place on the internet that tells you how it works. There’s a forum with a lot of information: 1 THREAD with 2,500 messages !??

That is why I have setup a small overview of how I configured my TK-103. These instructions will most likely also work for the Xexun TK-102.

Xexun TK 102  This is a ‘pocket’ tracker. Very small, with battery, built in antennas.

Xexun TK 103  More for a fixed mount in a car. Has a lot of extras like an external microphone, external antennas for GPS and Cell, ability to close switches remotely etc.

Data Connection

For the data connection I ordered a pre-paid SIM card with data. In the Netherlands I found Simyo.nl to be one of the cheapest. They charge per Kb which is very convenient as the tracker doesn’t send large amounts of data. I’m using a 10 euro card for over 1 year now. It does not have international data support.
