@FruityBebbles looks like the doc for the module references a google doc with says
directionsRequest Required The directions to show on the map.
Type: google.maps.DirectionsRequest interface
direction request link takes you here
https://developers.google.com/maps/documentation/javascript/reference/directions#DirectionsRequest
which says LatLng or LatLngLiteral
https://developers.google.com/maps/documentation/javascript/reference/coordinates#LatLngLiteral
which both show as this
{lat: -34, lng: 151}
so
module: "MMM-google-route",
position: "top_left",
config: {
key: "google api-key",
directionsRequest:{
origin: "address, city, country",
destination: {"lat": number, "lng":number}, // can't figure out...
height: "400px",//default=300px
width: "400px",//default=300px
avoidTolls: true,
showAge: false,
fontSize: "80%",
}
}
},
