ClimaViewer is a Linux-based tool designed to visualize and export temperature and humidity data from the DNT Raumklimastation RoomLogg PRO. It allows users to display real-time climate data and trends via a user-friendly web interface or in the console.
- Real-time monitoring of temperature and humidity via both web browser and console
- Data export for further analysis
- Visualized trends over time with graphs
- Runs out-of-the-box with basic shell commands – no need for additional environments like Python or Node.js
- Basic web view (without a web server) and extended web view (requires web server)
- Linux-based system (e.g., Raspbian on a Raspberry Pi)
- sudo apt install xxd
- Adjust the number and the names of channels in
cw.sh(line 6-14) - Update the names of your channels in
web/climaviewer.php(line 250-254) - Update the path to the SQLite DB in
db.sh(line 4) andweb/get_data.php(line 9)
Attach the USB cable to your device (e.g., Raspberry Pi or computer).
Create a cron job to fetch data every 5 minutes (sudo crontab -e):
*/5 * * * * /home/pi/ClimaViewer/cw.sh -j | /home/pi/ClimaViewer/db.sh >> /home/pi/ClimaViewer/logs/$(date '+\%Y-\%m')_ClimaViewer.log 2>&1
Update the paths according to your environment.
Copy the files from the web subfolder to a directory accessible by your web server (e.g., lighttpd). Example path: /var/www/html/.
