VSCP BME680 sensor handler

vscp-python-sensor-bme680

VSCP routines to deliver data from BME680 sensor to a VSCP daemon or a MQTT broker. It is built upon the Adafruit BME680 module

It will deliver VSCP events for

• Temperature
• Humidity
• Pressure (raw reading)
• Pressure (adjusted for sea level)
• Altitude
• Gas concentration

Typically used in a cron job to deliver the events on timed intervals.

Install

The script depends on some other modules that you need to install before using it. It is recommended to install everything in a virtual environment.

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate

You may need to install Python venv

apt install python3-venv

Configparser

Configparser can be found on PyPi and is documented https://docs.python.org/3/library/configparser.html. Install with

pip3 install configparser

Install adafruit-circuitpython-bme680 module

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-bme680

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-bme680

Install VSCP modules

pyvscphelper is not needed if only MQTT should be used. You can install the modules from PyPi

pip3 install pyvscp
pip3 install pyvscphelper

If you need them on more places either go for a global install or use a virtual environment and install all the modules in it.

Install MQTT module

For MQTT functionality Paho MQTT module is needed. You can install the modules from PyPi

pip3 install paho-mqtt

Install

You setup the code by editing the script. All relevant values are in the beginning of the file. Documentation is in the file.
