Support for personal automation

[chrisbergr]

This topic is about personal automation. I'm not sure if there is some overlap with #64

I'm pretty sure you could do some fancy things with it. But a great first step would be to set the value for "Tracking Enabled" to "on" or "off" after the trigger. Everything beyond is nice to have.

What I'd like to do:

When I leave my home, the "Travel trigger" should set the value "Tracking Enabled" in the overland app to "on", and when I get home, to "off" accordingly.
