New SD card configuration

This software requires Python 2 and will not work with Python 3. Support for Python 2 has been dropped in most new Raspberry Pi SD card images. For easiest setup please use a Buster compatible image. The last lite image provided by Rasbian is:

https://downloads.raspberrypi.org/raspios_lite_armhf/images/raspios_lite_armhf-2021-05-28/2021-05-07-raspios-buster-armhf-lite.zip

Please check your Python version before continuing using:

python -V

Which should report "Python 2.7.x"

If you are creating a new SD card image then you must configure the raspberry pi for your locale and to enable sensor interfaces using raspi-config. Use [tab] key to navigate between UI elements, [space] to select options, and [enter] to select buttons.

 sudo raspi-config

• Select Option 3 Interface Options -> P4 SPI -> Yes to enable SPI.
• Select Option 3 Interface Options -> P5 I2C -> Yes to enable I2C.

If not in UK set locale to your country

• Select Option 5 Localisation Options -> L1 Locale -> Use [down arrow] to find your desired language code e.g. en_US.UTF-8 (for USA) -> Select using [space] -> [OK] -> Select default locale to match previous selection e.g. en_US.UTF-8 -> [OK]
• Select Option 5 Localisation Options -> L2 Timezone -> e.g. America -> Los Angeles -> [OK]
• Select Option 5 Localisation Options -> L3 Keyboard -> e.g. Generic 105 key Intl -> Select appropriate keyboard layout. For US first select "Other" then "English (US) -> [OK] -> Use defaults [OK] -> No Compose Key [OK]

If using Wifi:

• Select Option 1 system Options -> S1 Wireless -> Select country [ok] -> Enter your wifi SSID [ok] -> Enter your wifi password [ok].

Optional but recommended:

Enable SSH to allow for remote command line interface.

• Select Option 3 Interface Options -> P2 SSH -> Yes to enable SSH.

Change hostname:

• Select Option 1 system Options -> S4 Hostname -> Enter your desired name e.g. "skyweatherpi" [enter]

Change "pi" user password:

IMPORTANT: If you have changed the keyboard layout please exit out of "raspi-config" and reboot before changing password.

• Select Option 1 system Options -> S3 Password -> Enter your desired password [enter]

New SD: Install core requirements

sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install -y build-essential python-smbus python-pip python-dev git libi2c-dev pigpio python-pigpio python-numpy python-matplotlib python-mpltoolkits.basemap python-picamera
sudo pip install --upgrade pip setuptools apscheduler requests

Install this next:

 cd ~
 git clone https://github.com/adafruit/Adafruit_Python_PureIO.git
 cd Adafruit_Python_PureIO
 sudo python setup.py install

New SD: Download SkyWeather

 cd ~
 git clone https://github.com/switchdoclabs/SDL_Pi_SkyWeather.git
 cd ~/SDL_Pi_SkyWeather/Adafruit_Python_BMP
 sudo python setup.py install
 cd ~/SDL_Pi_SkyWeather/Adafruit_Python_GPIO
 sudo python setup.py install
 cd ~/SDL_Pi_SkyWeather/Adafruit_Python_SSD1306
 sudo python setup.py install

New SD: Configuration settings

We recommend you copy config.py to conflocal.py to avoid updates copying over your configuration file.

 cd ~/SDL_Pi_SkyWeather
 cp config.py conflocal.py

Edit the setting:

 nano conflocal.py

New SD: Database configuration

If you plan on using the SQL database for data storage.

sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install mariadb-server python-mysqldb -y
sudo mysql_secure_installation
sudo mysql -u root -p < ~/SDL_Pi_SkyWeather/SkyWeatherSQLWeatherPiStructure.sql

Upgrading existing SD card

If you have an existing working SD card and wish to upgrade the SkyWeather code.

 cd ~/SDL_Pi_SkyWeather
 git pull

Existing SD: Updating conflocal.py

To merge new config.py variables into your conflocal.py version for compatibility run this command:

diff conflocal.py config.py

Check your new settings:

nano conflocal.py

Starting SkyWeather.py program

You start the program with two statements:

 sudo pigpiod
 sudo python SkyWeather.py

Auto start SkyWeather on Boot

Set up your rc.local for start on boot. Insert the following in your /etc/rc.local before the exit 0 statement:

 pigpiod
 cd /home/pi/SDL_Pi_SkyWeather
 nohup sudo python SkyWeather.py &

NOTE:

If you have a WXLink wireless transmitter installed, the software assumes you have connected your AM2315 outdoor temp/humidity sensor to the WXLink. If you put another AM2315 on your local system, it will use those values instead of the WXLink values
