## CONFIG:
## BME280 via I2C - TEMP, PRESSURE, HUMIDITY in Cone
## WS1080 Rain, Anemometer, Vane
## Status LED x2 - 1 in Cone & 1 in remote
## 64x128 OLED Screen via I2C
## Remote board is ~14ft. elevation in my back alley - one day will be mounted at approx 30' with no obstructions
## NodeMCU Board is connected via Cat5 DIY Patch Panel -> 50' CAT5 cable x2 + 14AWG wire for Status LED
##### Future Adds:
##### Light / Lightning / UV Sensor via I2C
