WeMos/Lolin D1 + BME280 - Environmental Data Fetcher - Python-Script for RaspberryPi/Linux - HTML-Graph

thingiverse

A simple script for collecting and storing the data from one or more environmental sensors (WeMos/Lolin D1 Mini with BME280 running my code https://www.thingiverse.com/thing:3152008 ) in csv-files. Make a cron-job to run this script regularly. Prerequisites: - pip install requests - One or more - depending on how many sensors you're running - csv-files. - Running the python-script for the first time will create the files on its own - The first line should be edited to look like this: Time(UTC),Temperature(°C),Humidity(%),Pressure(hPa) - Put a symbolic link of the CSV-files into the HTML-folder (usually under /var/www/ ) Update 2018-10-22 I've added a HTML-file which shows the collected data in a graph using Dygraph. Initially i wanted to make a single HTML-file which then would show all graphs on a single page, but i wasn't able to make this work. For now you have to copy and edit the file which then shows a single graph for each CSV-file you want. If anyone is able to do this more elegant please feel free to remix and share it with us. Update 2018-11-21 Edited and tested the script for use with python 3
