WTherm

This is a second rewritten version of my original WTherm project. This project was expanded as part of a final thesis which can be found in the report folder. The new WTherm has added functionality like scheduling, and uses a thermal model to predict the temperature. If you set the schedule to 20.0 degrees at 6:00, it will make sure that it reaches 20 degrees at exactly that time.

Installation instructions

sudo apt-get install php5-curl php5-cli
sudo service nginx restart
  • cd into your home directory: cd ~
  • Clone the git repo: git clone https://github.com/niekproductions/WTherm-alpha.git.
  • Create a symlink to it: cd /usr/local/bin && sudo ln -s ~/WTherm/code WTherm.
  • Import WTherm.sql into the MySQL server.
  • Edit the base.php configuration to suit your installation.
  • Add a new group of users that are allowed to control GPIO and add www-data to the group:
sudo groupadd GPIOcontrol
sudo usermod -a -G GPIOcontrol www-data
  • Allow the group to use the GPIO utility by adding the following line to the end of /etc/sudoers: %GPIOcontrol ALL=NOPASSWD: /usr/local/bin/gpio
  • Use crontab -e and add these lines to the end of the file to run the thermostat script every 5 minutes:
*/5 * * * * php5 /usr/local/bin/WTherm/thermostat.php >> /usr/local/bin/WTherm/wtherm.log
@reboot php5 /usr/local/bin/WTherm/startup.php >> /usr/local/bin/WTherm/wtherm.log &
  • And finally, add a user by executing the following command: php5 /usr/local/bin/WTherm/adduser.php [username] [password] [password-confirm] You should now be able to log into the WTherm!

optional

  • Set up nightly database backups by creating backup.sh:
#!/bin/bash
NOW=$(date +"%d-%m-%Y")

MUSER="WTherm"
MPASS="[database password]"
DB="wtherm"

FILE="$HOME/backup/wtherm-$NOW.gz"

/usr/bin/mysqldump -u $MUSER -p$MPASS $DB | /bin/gzip -9 > $FILE
  • Mark it as an executable script: chmod +x backup.sh
  • Add it to the crontab (crontab -e):
30 2 * * * ~/backup.sh
