MQTT_TOPIC_JSON option
By default, the status will be updated to the topic aw/data and the payload will be JSON received from the Ambient Weather query. Setting this to false will split each property in the JSON payload to individual topics, one for property.
Example of default behavior (MQTT_TOPIC_JSON=true or MQTT_TOPIC_JSON=):
{"dateutc":1537282680000,"tempf":85.6,"humidity":92,"hourlyrainin":0,"dailyrainin":0,"weeklyrainin":0,"monthlyrainin":1.83,"yearlyrainin":37.23,"totalrainin":37.23,"tempinf":87.8,"humidityin":63,"baromrelin":31.02,"baromabsin":30.06,"dewPoint":83,"lastRain":"2018-09-14T14:56:00.000Z","deviceId":"5a41138884f9e0000d5a822d","date":"2018-09-18T14:58:00.000Z"}Example of (MQTT_TOPIC_JSON=false), individual topics with the value as the payload:
