Control freezer temperature to keep kegs cold.
This project is meant to run on an Onion Omega2 (https://onion.io/). The python script is written for Python 2.7.
To install:
-
Copy the files to the Omega2. If not in /root, you'll need to change some paths.
-
Follow the 1-wire setup instructions at: https://wiki.onion.io/Tutorials/Reading-1Wire-Sensor-Data
-
A crontab file should be created:
-
-
-
-
- /usr/bin/python /root/tempcontrol.py
-
-
-
- Make a symbolic link for web display: ln -s /root/webkeezer/ /www/console/webkeezer
The script tempcontrol.py switches a relay on/off based on a temperature and the setpoint and temperature delta defined in lines 1 and 2 of keezerparams.txt.
Start the cron scheduler with: /etc/init.d/cron enable /etc/init.d/cron start
