Time schedule from Json

Hey guys,

I need to get the next train departure data from a Json and show it on HA dashboard, but I’ve no idea where/how to start.

The json data is:

    {
    "Weekdays": 
 ["05:20","05:48","05:55","06:12","06:20","06:37","06:45","07:02","07:10","07:15","07:27","07:35","07:45","07:55","08:05","08:10","08:20","08:30","08:40","08:50","09:00","09:10","09:20","09:25","09:35","09:45","09:55","10:15","10:30","10:55","11:15","11:40","11:55","12:10","12:25","12:40","13:00","13:20","13:35","13:50","14:05","14:20","14:35","14:50","15:05","15:20","15:33","15:47","16:05","16:15","16:30","16:45","16:55","17:05","17:15","17:25","17:35","17:45","17:55","18:05","18:12","18:22","18:32","18:37","18:50","18:57","19:07","19:17","19:25","19:35","19:52","20:14","20:38","20:55","21:27","21:57","22:21","22:45","23:09","23:33","00:05","00:40","01:20"],
  "Weekends":["05:20","06:00","06:30","07:00","07:15","07:30","07:55","08:10","08:30","08:50","09:10","09:30","09:50","10:10","10:30","10:50","11:10","11:35","11:55","12:20","12:45","13:10","13:35","14:00","14:20","14:40","15:00","15:20","15:40","16:06","16:20","16:40","17:00","17:20","17:40","18:00","18:20","18:40","19:00","19:25","19:50","19:50","20:10","20:35","21:00","21:30","22:00","22:30","23:00","23:30","00:05","00:40","01:20","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""]
}
