Import data

The goal of the app is to collect, organize, analyze and visualize weather data from your backyards weather station.

You need to export/backup the data from your weather station and import them as a .csv file into the app. You can also use your handwritten Excel lists or whatever - just save them as a .csv file with named headers, and you are good to go!

Currently, only .csv files with named headers are supported. You can manage the header names and the units within the app settings. You can also configure the input date and time format (this is important because various personal weather stations backup their data in different date formats).

Import settings

Before starting the first import, open the Import settings.

Open the settings via the right Sidebar. The right sidebar can be opened with the little button in the top right.

Headers

Under the heading Import you will find all the relevant import settings. You need to set all header names according to your csv file header naming.

Consider the following csv structure (table is split for better readability):

time	temperature	humidity	pressure	rain	solar
2022/11/30 17:21	10	80	950	0	100.4
2022/11/30 19:21	15.7	75	951	0.9	124.9
...	...	...	...	...	...

uvi	wind	wind_direction	gust	dew_point	felt_temperature
4	15	303	25	8	10
5	5	187	280	10	10
...	...	...	...	...	...

To import this csv successful you need to set

the option Header time to "time"
the option Header Pressure to "pressure"
the option Header Rain to "rain"
and so on...

Date format

You likely need to change the option Date format to match your data date and time format.

The default format is YYYY/M/D k:mm which translates to 2022/5/8 11:06. Other examples would be:

YYYY/MM/DD HH:mm is 2022/05/08 11:06
HH:mm - YYYY/DD/MM is 11:06 - 2022/08/05
DD.MM.YYYY HH:mm is 08.05.2022 11:06

Units

You can change the unit for each supported characteristic. Note: Setting this will only change the labels used within the app, there will be no conversion.

Import

If you followed the previous steps, you are now ready to hit the Import from CSV button and choose your file.

Navigate

Choose a date range and view every possible diagram for each characteristic.

Date selection

In the top bar there is a date range widget, with that you can set a custom date range to filter your data. Default value is the date of the first record and the date of the last record.

All tables, diagrams and stats respect the selected date range.

Pages

The app includes 7 pages:

Overview

This page provides a quick overview of all collected characteristics via a diagram and table view.

Temperature page

Diagrams

Temperature with stats (Ø per day)
Combined: Temperature, Felt temperature and Dew point (Ø per day)
Combined: Felt temperature Minimum & Maximum (Min/Max per day)
Combined with selectable date range: day, month or year: Minimum, maximum and average per date

Precipitation page

Diagrams

Annotated diagram per day with stats
Selectable date range day, week, month or year: Rain per date
Humidity (Ø per day)

Pressure page

Diagrams

Pressure (Ø per day)

Wind page

Diagrams

Wind (Ø/day) and Gust speed (max/day)
Wind direction (Ø per day)

Solar page

Diagrams

Solar radiation (Ø per day)
UV Index (Max per day)

Database page

A huge sortable table of all records.

Deleting records

You can either remove all records form your database or you can choose and remove single records.

First, go to the Database page. Select either single records you want to remove or select all records by clicking on the checkbox in the upper left of the table.

Data storage

All data you upload is stored only on your local filesystem.

On import, the data gets transformed and saved to your local filesystem. The folder is in your user data directory which is typically

For Linux, in ~/.config/weather-data-center/nedb
For Windows, in %LOCALAPPDATA%\weather-data-center\nedb
For MacOS, in ~/Library/Application Support/weather-data-center/nedb

Inside that folder you will find a file called data. Simply open it with a text editor of your choice. Please stop the app when editing this file directly.
