Life360 - Mapping

[whmoorejr]

Credit to neilk for pointing me in the right direction for this.

Below is some python bits that can be cut-up however you want. I included examples for geofences and L360 member devices. With this you can:

• Create a map showing the center point of your geofence and the radius you set in the L360 plugin.
  Create a map with any number of geofences as circles or points or both with any number of member devices.
  Create a map that can show the driving route between any two points (member -> member, geofence -> member, etc.)
  Create a map that can show a banner with the calculated distance between any two points.

You will need an API key (which is free and allows 15,000 requests per month) I included the URL for getting an API key and the URL for additional online documentation in the python bit.

Hopefully someone finds this useful for something.

whoa. This is awesome. I wonder if theres a way to make this functionality part of the plugin

I thought about that too. One trick would be metering it so you wouldn't go above a user's 15,000 asks / day. With multiple devices polling regularly, that would add up quick. Maybe something that only updates every x minutes after the device has traveled y distance... but that would add a lot of overhead to the plugin.

Simplest would be actions where the user could select the devices to map out and put those actions into schedules or triggers.

Either way, it's a bit beyond my abilities with plugin creation. But if you decide to go for it, hopefully what I posted helps out.
