MQTT Broker settings

MQTT allows the anemometer to publish wind data to a broker under a specific topic.
The broker then relays the messages to all clients subscribed to that topic.
This protocol is commonly used in IoT systems.

Messages

Messages are published periodically in JSON format:

• Instantaneous wind data is sent every 3 seconds when the device is not in Eco mode.

{
  "type": "INSTANT_WIND",
  "wind_instant_speed": 4.3,
  "wind_instant_dir": 237, // in degrees, ranging from 0 to 359
  "wind_instant_dir_cardinal": "WSW",
  "unit": "m/s"
}

• Minimum, maximum, and average wind values over the past 10 minutes are sent every minute (2 or 5 minutes in Eco mode). When a value is unavailable or cannot be computed, the corresponding field is set to null.

{
  "type": "MOVING_10MN",
  "wind_avg": 4.3,
  "wind_max": 1.74,
  "wind_min": 0,
  "wind_dir": 207, // in degrees, ranging from 0 to 359
  "wind_dir_cardinal": "SSW",
  "unit": "m/s"
}

• Device health information is sent every minute (2 or 5 minutes in Eco mode).

{
  "type": "DEVICE_HEALTH",
