Teleinfo Reader

Rust program that read serial data from teleinformation flux. Only work for the TEMPO subscription. Send data into PostgreSQL database.

Configuration

Create a .env file to configure the PostgreSQL connection with:

• the variable DATABASE_URL (like postgres://user:password@database-host:port/dbname, see diesel documentation for more information),
• the variable TELEINFO_SERIAL (path of serial device).

CLI scripts

Read teleinfomation data

The read-teleinfo executable read the serial data and send them into a PostgreSQL database.

Usage: read-teleinfo [-v] [-c file] [device]

The device path can be force. In this way, the device path set in the configuration file is ignored. The configuration file path can be force to read a specific configuration. By default, the script read /etc/read-teleinfo.conf and .env file.

Data generator

The data-generator executable open a file socket and send fake serial data into it.

Show stored data

The show-data executable read and show the last values from the PostgreSQL database.

Usage: show-data [-c file]

The configuration file path can be force to read a specific configuration. By default, the script read /etc/read-teleinfo.conf and .env file.

Dump data stored in database

The dump command export all data stored in the PostgreSQL database in CSV format.

Usage: dump [-c file] output

The configuration file path can be force to read a specific configuration. By default, the script read /etc/read-teleinfo.conf and .env file. output is the output path.

Test with the data generator

Run the data generator script to create file socket and send data into it:

cargo run --bin data-generator

Run the reader script to read data from /tmp/output:

cargo run --bin read-teleinfo /tmp/output -v

Deploy executable by creating debian package that install a systemd service

First, install cargo-deb:

cargo install cargo-deb

Build the debian package:

cargo build --release && cargo deb

Install the debian package:

sudo dpkg -i target/debian/teleinfo_reader_<version>_<arch>.deb

Configure the device path and database access by editing the /etc/read-teleinfo.conf.

Reload the daemon:

sudo systemctl restart read-teleinfo

Check that the service is active:

sudo systemctl status read-teleinfo
sudo journalctl -u read-teleinfo  # to see the logs

Uninstall the package:

sudo dpkg --purge read-teleinfo_reader
