Yep, that's a university project too!

Weather station

Install

DB

Create a database:

intidb <file> -E utf8

psql
=# CREATE DATABASE stacja;
<Ctrl-D>

psql -d stacja < dump.sql
=# CREATE USER pi WITH PASSWORD '<password>';
=# GRANT USAGE, SELECT ON readings TO pi;
=# GRANT USAGE, SELECT ON SEQUENCE readings_id_seq TO pi;

Express server

Install server:

npm install

Script

Install python dependencies:

pip3 install -r requirements.txt

.env

Copy and fill .env:

cp .env.sample .env
vim .env

Run on boot

# change neccessary variables in services/weather-{script|server-express} files
# add services
# usage: sudo service weather-{scripts|server-express} {start|stop|status}
sudo ln -v <project-dir>/services/weather-script.sh /etc/init.d/weather-script
sudo ln -v <project-dir>/services/weather-server-express.sh /etc/init.d/weather-server-express

# run services at boot
sudo update-rc.d weather-script defaults
sudo update-rc.d weather-server-express defaults

Use Grafana (on Raspberry Pi Zero W)

Install some packages and add the bintray pubkey to the apt keyring:

sudo apt-get install apt-transport-https curl
curl https://bintray.com/user/downloadSubjectPublicKey?username=bintray | sudo apt-key add -

Update your apt source

echo "deb https://dl.bintray.com/fg2it/deb-rpi-1b jessie main" | sudo tee -a /etc/apt/sources.list.d/grafana.list

Install

sudo apt-get update
sudo apt-get install grafana

For more see: https://www.circuits.dk/install-grafana-influxdb-raspberry/#

Start at boot

Check if /etc/systemd/system/grafana-server.service is a correct link to /lib/systemd/system/grafana-server.service.

If not, create /lib/systemd/system/grafana-server.service the source file is here.

Then create the correct link:

sudo ln -s /lib/systemd/system/grafana-server.service /etc/systemd/system/grafana-server.service

Then enable grafana-server;

sudo systemctl enable grafana-server

Then start grafana-server

sudo systemctl start grafana-server
