BSEC-Conduit Daemon FORK for HASSIO

A first class Systemd process which acts as a conduit between between BSEC-Library and MQTT. Provides an alternative method of getting data out of an I2C connected Bosch BME680 sensor and into Home Assistant. Much more accurate than the native HA BME680 module, as it uses the Bosch Sensortec Environmental Cluster (BSEC) fusion library to process the raw BME680 sensor readings.

Requirements

• python-systemd
• paho.mqtt

sudo apt-get install python3-pip

sudo apt-get install python3-systemd python3-paho.mqtt or pip3 install python-systemd paho.mqtt

Installation

In this example we'll be installing into a Python venv located at /opt/bsec with the user pi on a recent Debian based distro (Raspbian/Hassbian). You can use any location and user you want, just make sure they are a member of the i2c group.

• sudo raspi-config > interfacing options > enable I2C
• sudo mkdir /opt/bsec Create the directory.
• sudo chown pi:pi /opt/bsec Change permissions on the directory.
• sudo -u pi git clone https://github.com/badstraw360/BSEC-Conduit.git /opt/bsec Clone the repo into our new directory.
• sudo -u pi python3 -m venv /opt/bsec Create our venv.
• cd /opt/bsec Change into the directory.
• source bin/activate Activate our new venv.
• sudo -u pi pip3 install systemd-python paho-mqtt Install required Python modules.
• sudo python3 install.py Run the installer.
• sudo -u pi nano bsec-conduit.ini Edit the config section at the top of the file. Use CTRL-X to save.
• sudo systemctl start bsec-conduit.service; journalctl -f -u bsec-conduit.service Start the program and open the log file.

Usage

Here's a typical log output when started for the first time, stopping and subsequent runs:

iT'S VERY IMPORTANT TO ENABLE THE SERVICE ONCE IT'S WORKING:

sudo systemctl enable bsec-conduit.service
