Telemetry

How it reports

  • Wind speed is sampled for 60 - 120 seconds before each upload.
  • The station uploads to the iWeathar server every 10 minutes.
  • During heavy rainfall (over 16 mm) the interval drops to as little as 3 minutes for flood warnings.
  • Readings are stored permanently on the iWeathar server, and optionally on a micro-SD card in the unit.
