I’m using the RESTful integration to acquire data for my bus stop, especially the next three departures for a specific bus line. I’m trying to fetch these values from the JSON response and use them in a sensor. My sensor configuration is below:
- platform: rest method: POST name: HSL_LPV_550 resource: https://api.digitransit.fi/routing/v1/routers/hsl/index/graphql payload: '{ stop(id: "HSL:1463113") { stopTimesForPattern(id: "HSL:2550:0:01", numberOfDepartures: 3) { realtimeArrival } }}' headers: Content-Type: application/graphqlThe POST request gives a response of:
{ "data": { "stop": { "stopTimesForPattern": [ { "realtimeArrival": 71746 }, { "realtimeArrival": 72527 }, { "realtimeArrival": 72892 } ] } } }The above response contains the desired next three departures, the format is seconds from midnight.
However, here comes the tricky part. I would like to use the values to determine the sensor value and a sensor attribute according to the following formula (I’m comparing the realtimeArrival to the current time):
IF:
the difference on first timestamp and current time is under 4 minutes, set the second timestamp difference as sensor value and third timestamp difference as sensor attribute called next.
ELSE:
set the first timestamp difference as sensor value and second timestamp difference as sensor attribute called next.I could extract the time difference of first arrival and current time in minutes using the following:
{% set current_time = ((now().hour*60+now().minute)*60+now().second) %} {% set arrival_time = (value_json.data.stop.stopTimesForPattern[0].realtimeArrival) %} {% set ETA = ((arrival_time-current_time)/60) | int %}My issue could be broken to the following parts:
- I don’t know how to extract all three values of the JSON reply and use them in value_template, as they have same names
- I don’t know how I can use IF-ELSE statement as described above, this seems trivial as long as I have the three values available somewhere.
