Alerts only returns 1 alert when there can be many

[blackeneth]

Today in the Philly area there are 3 alerts:

{"lat":39.87,"lon":-75.23,"timezone":"America/New_York","timezone_offset":-14400,"alerts":[{"sender_name":"NWS Philadelphia - Mount Holly (New Jersey, Delaware, Southeastern Pennsylvania)","event":"Heat Advisory","start":1626102000,"end":1626220800,"description":"...HEAT ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT TUESDAY...\n* WHAT...Heat index values between 100 to 105 expected.\n* WHERE...In New Jersey, Gloucester, Northwestern Burlington and\nCamden.

OWOC will only return the first alert.

OWOC.alert->summary

An enhancement would be store all alerts, to allow them to be queried

OWOC.alert[x].event
OWOC.alert[x].description 
OWOC.alert[x].start
OWOC.alert[x].end
OWOC.alert[x].sender_name
OWOC.alert[x].tags

The ArduinoJson helper comes up with this structure:

for (JsonObject elem : doc["alerts"].as<JsonArray>()) {

  const char* sender_name = elem["sender_name"]; // "NWS Philadelphia - Mount Holly (New Jersey, Delaware, ...
  const char* event = elem["event"]; // "Heat Advisory", "Flash Flood Watch", "Flood Advisory"
  long start = elem["start"]; // 1626102000, 1626103380, 1626118200
  long end = elem["end"]; // 1626220800, 1626166800, 1626145200
  const char* description = elem["description"]; // "...HEAT ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT ...

  const char* tags_0 = elem["tags"][0]; // "Extreme temperature value", "Flood", "Flood"

}

Another field would be needed to let the programmer know the maximum "x" to retrieve alerts for.

Thank you for your consideration.

Thank you, I initially entertained being able to store more than 1 alert. However, the number of areas with more than 1 alert at a time is very small given the area of the Earth, and the memory required to store full information for all alerts in areas with more than 2 would be prohibitive. However, I do continually monitor alerts and evaluate including said routine in the program.
