fronius-mqtt-bridge

Python scripts

• to fetch data from various APIs like power flow realtime data from a fronius data manager and pubish it to a mqtt broker.
• for implementing controll-algorithms based on and setting via mqtt topics

I use it with this setup.

Requirements

• Tested with Python 3.5 on raspian

Usage

Create, activate and setup venv:

cd fronius-mqtt-bridge
python3 -m venv ./venv
source venv/bin/activate
pip install -r requirements.txt

Then set the right hostnames or ip addresss and ports in all python files that will be used and run for example:

python3 fronius-connector.py

The scripts will run in an infinite loop until an error happens or they are aborted via Ctrl+C.
