pi-energy-reader

Schedule data collection from energy meters connected to a Raspberry Pi and push it to an MQTT Broker.

• Supports MODBUS energy meters
• No need to write custom code to use it
• MQTT Integrated
• Lightweight

Getting started

This project is designed to work on a Raspberry Pi. It has only been tested on a Raspberry Pi 3 B+, but it should work on any version of the board.

Installation

Fist of all, clone the project somewhere in your system and cd into it.

git clone https://github.com/samueleallegranza/pi-energy-reader.git

For the project dependencies, it's reccomended to use a Python3 virtual environment. You'll need to install virtualenv from pip. Then create a virtualenv folder inside the project's folder, activate the environment and download all the dependencies contained in requirements.txt

pip3 install virtualenv
virtualenv venv
. venv/bin/activate
pip3 install -r requirements.txt

To deactivate the virtualenv use the deactivate command

Run on startup

Once you tested the project and got it up and running, the need to run the project on boot may arise. This way, you won't need to restart everything manually every time the power goes out.

To achieve this, is necessary to run the project as a service on linux (systemd). An example of .service file has been already created and tested for you, you can find it in examples/energyReader.service. All you need to do is to adjust the paths with yours. Then copy the file into the systemd directory and reload:

[!] The use of absolute paths is highy recommended

cp examples/energyReader.service /etc/systemd/system/
sudo systemctl daemon-reload

To start the service use

sudo systemctl start energyReader.service

To check its status use

sudo systemctl status energyReader.service

If you need to restart the service for some reasons, use

sudo systemctl restart energyReader.service
