Looking good

Moving creation of the "readings" variable into the function using it solved the memory leak issue.

Thanks again for all you do for this community!

// Get Sensor Readings and return JSON object
String getSensorReadings()
{ 
  StaticJsonDocument<500> readings; 
  String jsonString; 
  readings["temperature"] = String(1.8*bme.readTemperature()+32);
  readings["humidity"] =  String(bme.readHumidity()+3.1);
  readings["pressure"] = String(bme.readPressure()/3312.50);
  readings["windspeed"] = String(windspeed);
  serializeJson(readings, jsonString);   
  Serial.println(jsonString);    
  return jsonString;  
 }
