Weather Station Simulator

Runs the logic of firmware v3 (RAK3172, main board Rev B) against weather you set: pulse counting, the 16-position wind vane ladder, the 46-byte uplink, store-and-forward during gateway outages and the network server's decoder. Weather inputs and the wind factor are illustrative; the firmware rules are taken from weather_station.ino.

Station

18650 cell voltage

Reed pick-up half-angle

Report every min PM every reports

These two act like the port-10 downlinks 01 MM MM and 02 NN. Firmware v3 accepts 1 to 1092 minutes, the most the 16-bit interval field can hold, and skips the PM sensor while the battery reads below 3.4 V.

Wind pulses use an assumed 0.7 m/s per Hz only to drive the simulation. The real factor comes from the calibration run, and until then the decoder reports frequency, not speed.
