bme680_to_influxdb - BME680 Monitoring with InfluxDB
This script sends the data from the RaspberryPI Bosch BME680 module to a InfluxDB. The script itself and the documentation is work-in-progress. However, feel free to open issues for your questions and ideas.
Feel free to read the full story on how to send BME680 sensor logs with a RaspberryPi to InfluxDB and into Grafana on ayeks.de.
Installation
InfluxDB on a RaspberryPI
Download and install the InfluxDB ARM package:
wget http://ftp.us.debian.org/debian/pool/main/i/influxdb/influxdb_1.1.1+dfsg1-4+b2_armhf.deb
sudo dpkg -i influxdb_1.1.1+dfsg1-4+b2_armhf.deb
Modify influxdb.conf to enable admin GUI and restart the database.
sudo nano /etc/influxdb/influxdb.conf
sudo service influxdb restart
Go to the admin GUI of the InfluxDB and create a new database with the name logger:
# goto: http://localhost:8083/
CREATE DATABASE "logger"
BME680_to_InfluxDB on a RaspberryPI
You need the bme680 python lib, the InfluxDB client and the bme680_to_influx script.
git clone https://github.com/ayeks/bme680_to_influxdb
cd bme680_to_influxdb
pip3 install -r requirements.txt
Go to the config.ini file and change the values to match your environment. You should change at least host, user and the password.
Execution
Simply call: python3 senddata.py "./config.ini" .
Often you want your Raspberry to execute the senddata script automatically after it started. Use the following to do so:
# automated startup:
sudo nano /etc/rc.local
python3 /home/pi/senddata.py "/home/pi/config.ini" &
Analysis
Collecting data is just half the fun without proper analyzing. To crawl through your data just use the InfluxDB admin GUI:
# select the "logger" database first!
# show all available measurements
SHOW MEASUREMENTS
# show available tags for measurement
SHOW TAG KEYS FROM "dev"
# get results by measurement
select * from dev
In this repo is the JSON included that generates the following Grafana Dashboard:
