netatmo-to-json

This project writes data from your Netatmo weather station to a JSON file that can be read by PyMultimonAPRS https://asdil12.github.io/pymultimonaprs

Getting Started

source set_env.sh
python3 fetch-netatmp.py

Weather file format

The format of the file as required by PyMultimonAPRS is as follows:

{
	"timestamp": 1366148418,
	"wind": {
		"speed": 10,
		"direction": 240,
		"gust": 200
	},
	"temperature": 18.5,
	"rain": {
		"rainlast1h": 10,

	},
	"humidity": 20,
	"pressure": 1013.25
