GoWeather

A way to read data from a USB weatherstation based on the FineOffset WH1080 or compatible device.

This is meant to be used as a way to read data from the device and return something that can be used for other applications

Usage

# get deps
go get -v
# build it
go build -o goweather main.go types.go
# run it
./goweather
