This rule template uses the Waze RoutingManager API to query for and calculate the time and distance to drive between two points. My original idea for this template was to get an alert in the mornings so we know when to leave early because there’s yet another accident on the interstate.
The template has four properties:
- starting coordinates in “lat,lon” format
- ending coordinates in “lat,lon” format
Number:TimeItem that will be updated with the current driving timeNumber:LengthItem that will be updated with the current driving distance
This rule template does not have any triggers or conditions. To avoid hammering the Waze servers this rule remains inert until you further add your own triggers and conditions. I recommend a polling period in minutes at the most and adding conditions so the rule does not run at times when it’s not needed.
If more than one route is desired, create multiple rules using this template, one for each route.
