#pi-wind
Sends wind speed and direction data to weatherunderground from a raspberry pi hooked up to a KM53B88 Anemometer, uses the MODBUS-RTU protocol via a RS485 shield attached to a RaspberryPi 3.
Add a .env file containing

some options such as debugging and time between sending data to weather underground
can be set in settings.py

- khla/sonbest KM53B88 Anemometer http://www.sonbus.com/english/products/detail/KM53B88.html
- seedstudio RS-485-Shield https://www.seeedstudio.com/RS-485-Shield-for-Raspberry-Pi.html
Also a weatherunderground account.
- Receive nothing back from the KM53B88 Anemometer - make sure you have the correct unit id. Mine was set to 4 when the docs said it should be 1 from the factory.
- I was unable to get PyModbus or Minimal modbus to work with the rs485 hat.
