BlueWeather

A (hopefully soon) fully featured selft-hosted web interface and server-backend to store weather data (comparable to opensensemap.org)

State of development

• interface and backend planned
• readonly dashboard is working

Installation

1. Install the required packages

sudo apt install git apache2 mysql-server mysql-client php libapache2-mod-php php-mysql php-cli php-common -y

2. Prepare the working directory and download SafeMail

cd /var/www/html/

git clone https://git.itsblue.de/dorian/blueweather.git

3. Create the database

sudo mysql -u root

CREATE DATABASE blueweather;

4. now create the database user, if you change the username, password or database name, don't forget to change that data in the config.php file!

GRANT ALL ON blueweather.* TO 'blueweather'@'localhost' IDENTIFIED BY 'root';

FLUSH PRIVILEGES;

exit;

5. Prepare database for usage (create Tables and Keys)

cd /var/www/html/blueweather/api

sudo mysql -u root blueweather < blueweather.sql

Your BlueWeather instance can now be reached under: <your_ip>/blueweather

- signature: SHA1 Hash of the JSON encoded string of 'data' rsa encrypted with the API Key as private key
- data: JSON array[array[
        sensorId,
        measvalue,
        timestamp
    ]]
    CAUTION!! This MUST be a string and NOT direct JSON!!
### Reply

    - 500: internal error 
    - 900: format of data JSON string was invalid
    - 901: signature was fine but one or more sensors have been ignored due to some error (see 'data') all other sensors were processes successfully
- data: Array[Array[sensorId, errorCode]] sensors which were ignored due to some error (401: user doesn't own sensor; 404: senso wasn't found) 
        only set if status is 901
