Python code for Raspberry Pi + BME680 to update the cloud service WeatherUnderground.
This code is a fork of https://github.com/pimoroni/bme680-python.

Collect data from all the sensors, calculate and send the average of each over a period to prevent variation/noise in the acquisition.
Optionally, a second counter, multiple of the first counter, can execute an additional task.
The credentials are not hard-coded, but Linux environment variables.
Clone this repo and execute the installation script of BME680 module:
git clone https://github.com/davift/rpi-bme680-wu.git
cd rpi-bme680-wu
sudo ./bme680-instal.sh
Add your WU credentials as environment variables in file /etc/environment:
WU_ID=__ID_HERE__
WU_PASS=__PASSWORD_HERE__
Then, create service:
sudo nano /etc/systemd/system/rpi-bme680-wu.service
Add the following content replacing the path accordingly:
[Unit]
Description=RaspberryPi_BME680_WeatherUnderground
[Service]
User=root
Restart=always
RestartSec=10
EnvironmentFile=/etc/environment
WorkingDirectory=/__PATH__/rpi-bme680-wu/
ExecStart=python read-all.py
StandardOutput=file:/__PATH__/rpi-bme680-wu/session-output.log
StandardError=append:/__PATH__/rpi-bme680-wu/alltimes-error.log
[Install]
WantedBy=multi-user.target
Enable to load the script during the boot and start the service:
sudo systemctl daemon-reload
sudo systemctl enable rpi-bme680-wu.service
sudo systemctl start rpi-bme680-wu.service
Ideally, this code runs as a service managed by the systemd, which will restart if it crashes, and load on boot.
Additional commands for managing this service are:
sudo systemctl status rpi-bme680-wu.service
sudo systemctl stop rpi-bme680-wu.service
This code converts the acquired unities to meet the WU requirements.
The dew point is calculated from temperature and humidity.
The air quality index is not supported by WU.
- winddir - 0-360 instantaneous wind direction
- windspeedmph - mph instantaneous wind speed
- windgustmph - mph current wind gust, using software specific time period
