Modbus Wallbox Monitor and Signal Messenger

Overview

This project consists of a Python application designed to monitor a Modbus-enabled Wallbox (charging station) and send updates via Signal Messenger. It reads various parameters like the status of the charging point, total energy, and RFID tags from the Wallbox, and then sends notifications about these parameters to a specified Signal Messenger recipient.

Features

  • Monitor status, total energy, and charged energy of a Wallbox via Modbus TCP.
  • Read RFID tags associated with charging sessions.
  • Send updates and alerts via Signal Messenger.
  • Log data to a CSV file for each Wallbox.

Configuration

The application is configured through a config.yaml file. This file contains settings for:

  • Modbus connection (Host, Port, and Wallbox Name).
  • Modbus register addresses for different parameters (status, total energy, etc.).
  • Signal Messenger settings (Host, Port, Own Number, Send Number, and Check Frequency).

An example configuration is as follows:

log_level: DEBUG
modbus: 
  host: 192.168.178.95
  ...
signal:
  host: 192.168.178.23
  ...

Installation

To run this project, you need Python 3 and several Python packages including pymodbus, requests, pyyaml, and csv. These packages can be installed using pip.

Usage

Start the application by running the main.py script. This script will continuously monitor the Wallbox, read data from the configured registers, and send updates via Signal Messenger based on status changes or charging session events. Transactions are logged into a CSV file named after the Wallbox, with spaces in names replaced by underscores.

Logging

The application's operational details are logged, and the level of verbosity can be adjusted through the log_level setting in the config.yaml file.
