This is because min_level was adjusted recently. Now we check if 500L and 1000L belongs to the given intervals, and we do not assum they are lower bounds of such intervals.
Get current fioul price from Bretagne Multi Énergie and store it. Also with an incredible web interface to list price history.
Requirements
This project is written in Python and uses the following libraries:
- requests: to retrieve current price using a GraphQL query;
- peewee: a simple ORM, to store and query the data in a SQL database;
- bottle: a micro web framework.
Those libraries are all packaged in Debian and can be installed with:
apt install python3-request python3-peewee python3-bottle
Optional: a MySQL server (although switching to another database should be easy). Otherwise, a SQLite backend can be used.
Installation
We suppose the repository is cloned under /opt/fioul.
Create a fioul.ini config file, and fill in MySQL credentials. You can use
fioul.ini.example as a starting point. MySQL database can be created with the
following commands:
create database fiouldb;
create user 'fioul'@'localhost' identified by 'fioul_is_beautifioul';
grant all privileges on fiouldb.* TO 'fioul'@'localhost';
Tables can be created by running ./fioul.py initdb
To update the database day at 9:30am, the following line can be installed as a cronjob:
30 09 * * * /opt/fioul/fioul.py update
To launch the server automatically, you can install and use the systemd service file :
adduser --system --group --no-create-home fioul
ln -s /opt/fioul/fioul.service /etc/systemd/system/fioul.service
systemctl enable fioul.service
systemctl start fioul.service
The server listens to port 9980 on localhost by default, unless otherwise specified in the config file. Setting up a reverse proxy and ssl is left as an exercise to the reader.
