The following is my config:
- platform: rest
name: waze
resource: "http://my.domain/waze/routeHome.php?lat={{ state_attr('person.andreash', 'latitude') }}&lon={{ state_attr('person.andreash', 'longitude') }}"
value_template: '{{ value_json["route 1 name"] }}'
json_attributes:
- "route 1 name"
- "route 1 duration"
- "route 1 delay"
- "route 2 name"
- "route 2 duration"
- "route 2 delay"
- "route 3 name"
- "route 3 duration"
- "route 3 delay"
- "route 4 name"
- "route 4 duration"
- "route 4 delay"
scan_interval: 120
The link equals in template tools:
http://my.domain/waze/routeHome.php?lat=56.00865849&lon=12.76764844
The actual GPS position is set using a mock locations app.
Page returns the following:
{
"route 1 name":"E6 \/ E20 S; Fjelievägen",
"route 1 duration":37,
"route 1 delay":0,
"route 2 name":"E6 \/ E20 S; M 923",
"route 2 duration":44,
"route 2 delay":0,
"route 3 name":"N\/A",
"route 3 duration":"N\/A",
"route 3 delay":"N\/A",
"route 4 name":"N\/A",
"route 4 duration":"N\/A",
"route 4 delay":"N\/A"
}
“N/A” you ask…?
Yes… The PHP code makes sure there is four groups of values:
$i=1;
foreach($routes as $name => $time){
$arr['route ' . $i . " name"] = $name;
$arr['route ' . $i . " duration"] = $time['timeMin'];
$arr['route ' . $i . " delay"] = ($time["timeMin"]-$time["timeNMin"]);
$i++;
}
for($i; $i<=4;$i++){
$arr['route ' . $i . " name"] = "N/A";
$arr['route ' . $i . " duration"] = "N/A";
$arr['route ' . $i . " delay"] = "N/A";
}
echo json_encode($arr, JSON_UNESCAPED_UNICODE );
Meaning, if routes array has less than four items then the for loop below will “trigger” and create the remaining, as the json above shows.
Now… This is what HA gives me:
And that can only happen if the link HA uses is incorrect with lat/lon that returns no results at all…
But since my debug link is copied from a template tool output, that can’t happen.
Or can it?
Can anyone see the error?
Or is there anything that could make this easier? I can’t seem add an array as json_attribute, or is that possible?
