gonetatmo

Overview

This is a CLI tool to retrieve data from a personal weather station of Netatmo.

Demo

In this demonstration, at first, it retrieves data from own Netatmo. And then, all values in a square area 50 km on a side are retrieved as centering on Tokyo station, and the average values are displayed.

Description

I have a personal weather station of Netatmo. I check the data of my local environment using it. In most case, I have used my browser to retrieve the data so far. About retrieving data using curl, I have created it before. Recently, I thought that I wanted to create this as a CLI too. So I created this. This tool can retrieve not only the data of own Netatmo, but also the data of specific area using Netatmo APIs. By this, I got to be able to retrieve easily the data of various places. This tool has the following features.

• Retrieves data from Netatmo.
• Using Getstationsdata, retrieve data of own Netatmo.
• Using Getmeasure, retrieve past data of own Netatmo.
• Using Getpublicdata, retrieve data of various places.
  • For using Getpublicdata, you can retrieve data by inputting the address using Google Maps Geocoding API.

How to Install

Download an executable file of gonetatmo from the release page and import to a directory with path.

or

Use go get.

$ go get -u github.com/tanaikech/gonetatmo

Usage

Help

$ gonetatmo --help

Retrieve data from own Netatmo

$ gonetatmo

• This can be seen at the demonstration movie.
• If you want to retrieve the data as JSON object, please run as follows. In this case, the raw data from Netatmo can be retrieved.
• $ gonetatmo -raw

Retrieve past data from own Netatmo

$ gonetatmo m -di "### your device ID ###" -b 2018-01-01T00:00:00+00:00 -e 2018-01-02T00:00:00+00:00

• -b 2018-01-01T00:00:00+00:00 and -e 2018-01-02T00:00:00+00:00 mean that the data from 2018-01-01T00:00:00+00:00 to 2018-01-02T00:00:00+00:00.

Retrieve data of a specific area using latitude and longitude

$ gonetatmo p -lat 35.681167 -lon 139.767052 -r 50

• -r 50 means that all values in a square area 50 km on a side are retrieved as centering on (35.681167, 139.767052), and the average values are displayed.
• When -raw is used, you can retrieve the raw data from Netatmo.

Retrieve data of a specific area using address and place name

$ gonetatmo p -a "tokyo station" -r 50

• In this case, API key for using Google Maps Geocoding API is required.
• This can be seen at the demonstration movie.

About the retrieved area

When you run the command of $ gonetatmo p -a "tokyo station" -r 50, the following flow is run.

1. "tokyo station" is converted to the coordinate using Google Maps Geocoding API.
   • The converted coordinate means the center of area.
   • It's (35.6811673000, 139.7670516000).
2. -r 50 means a square area 50 km on a side.
   • The coordinates of North east corner and South west corner are calculated.
   • Those are (35.9064834975, 140.0432177479) and 35.4558511025, 139.4908854521.
3. All values of the square area 50 km on a side are retrieved using Netatmo API.

You can see above flow as an image. The orange anchor is the center coordinate. The green anchors of upper right and lower left are the calculated points. The values are retrieved from the red colored area.
