Connect to Fluvius smart energy meter via P1 and publish data via MQTT broker to Home Assistant

I created a python script that runs as a service to read out the Fluvius energy meter via the P1 port to USB on a Raspberry Pi. See installation notes here: https://github.com/smartathome/fluvius2mqtt/tree/main

The output into Home Assistant looks like this:

Testing a basic Zwave setup for the first time

I have myself ordered a Zwave.me USB stick and an Aeotec MultiSensor 6 to start building my sensor network at home. There are a few tools out there to get you started with Zwave on a Raspberry Pi, or see my howto. But the issue I had was that I was not able to see the technical configuration of my hardware devices. There is a script called api_help.py that comes with the python_openzwave library, that I have slightly modified so that it prints the useful information in a friendly way.

Output:

Install Louie for Python3

I needed Louie for a Python3 script, but it is not available through apt-get. To install directly from the github, just use the following command which makes use of pip3.

pi@raspberrypi:~ $ sudo pip3 install git+git://github.com/11craft/louie.git

In order to check for the installed modules in your python3 installation:

>>> import pip
>>> installed_packages = pip.get_installed_distributions()
>>> installed_packages_list = sorted(["%s==%s" % (i.key, i.version)
...      for i in installed_packages])
>>> print(installed_packages_list)
