Rail-Meter-TX

Rail Meter Transmitter is intended to send DTSU666 data to InfluxDB using Modbus through python.

This project was made for my use case. I commented out some parameters I do not intend to use, so they don't take unnecessary space on my InfluxDB.

The file app/DTSU666_2019.py holds the addresses for my device (manufactured in 2020) found on the device manual dtsu666_series_2019.pdf. I found that the same models fabricated before can have different addresses (like 2016 for example).

Feel free to fork this project and modify it to yourself.

Usage

You can run this script directly with a python interpreter or as a Docker container.

If you choose to run just using python (on a embedded system) you need to:

clone repo git clone https://github.com/onvrb/Rail-Meter-TX (and enter project with cd Rail-Meter-TX)
setup a venv (recommended) python3 -m venv venv and enter source venv/bin/activate
install the requirements pip3 install -r requirements.txt
setup the environments on your host, or hard-code it into the app/run.py
run script python3 app/run.py

or

Using Docker:

Create a docker-compose.yml file:
Change the environments to suit your needs and run.
