Here is a first stab at getting data uploaded to a better route planner ( https://abetterrouteplanner.com/ ). You will need a couple of things -
-
Your token or email address - this is found on the https://abetterrouteplanner.com/ after you have logged in -
Show Settings
Show More Settings
Live Car Connection Setup
Next until User Email Address is shown - copy that here -
API token - can be obtained from contact@iternio.com, but I’m hoping we can share the same one
Custom code script is -
import time
import logging
import requests
import json
import urllib
log = logging.getLogger(__name__)

Issues I’ve seen so far are -
- AttributeError: ‘module’ object has no attribute ‘time’
- OBD operations failing when they return zero. Sigh.
- I don’t think the car_model is quite correct
So I’m pretty sure this still needs work … but sharing all the same.
Note that the route planner folks are interested in doing this properly - I suppose this could be a plug-in on the cloud so its very easy for all to use.
