On my Car Integration page you can see how I have setup a tracking system that integrates with Homeseer. What I really wanted is Geofences. This results in a couple of HS devices that tell me where my car is.

Example: When my car enters a geofence I get a push notification.
Example: When my car leaves a geofence the thermostat is set to 17 degrees

How does it work?

1. On the gps-trace website you create geo-fences that ‘define’ your home, work and other important locations
2. On the gps-trace website you create notifications that send emails to HS, triggered by entering/exiting the geo-fences from step 1
3. Emails are send to an email address which is monitored by Homeseer.
   Based on the email content a script is started.
4. Homeseer runs this script that sets device status

For more information check out the GPS Geo Fence script page.

Cheers!
