This project, H-BACK, helps you take back your HVAC by using a tally of devices connected to a wireless network, along with predefined information about the room (dimensions, insulation R value, desired temperatures, etc.) to determine how to adjust the HVAC settings in order to maintain the current temperature in the room.
It's a basic functioning prototype, not feature-complete.
H-BACK detects devices on a network by running an ARP request and subtracting a predefined number of known non-wireless hosts to determine occupancy.
- Python 3
- Apache
- Linux (tested on Ubuntu 22.04 LTS, but should work on any modern distro)
- net-tools
- Know your IP on the network you want to scan (use
ifconfig) - Know how many devices on that network you want to exclude from the calculations (use
nmap, or check your router's connected device page)
- Simply clone the repository to an Apache2 web server's directory (
/var/www/htmlby default) - Start the Apache service:
(Replace
sudo systemctl start apache2.service
startwithenableif you want the service to persist across reboots) - Test the system by running the
update.pyscript:python3 updater.py
- The numbers on the GREEN indicators of the website should start gradually counting up.
- If all goes well, your web server, Python 3, JavaScript, CSS, and HTML are all in the right place.
- End the previous Python 3 script, then start the script that actually deals with the wireless devices:
python3 updater2.py
- You should see a string of numbers on your terminal. This is the current number of devices that have been detected MINUS the number of devices you want excluded from the count. The boxes on the web page should also reflect this.
