misfans
rPi experiment to automate a fan accesory to switch between ON/OFF based on temperature measurements.
Requirements
A ruby runtime installed. If new to ruby my personal recommendation is RVM:
curl -sSL https://get.rvm.io | bash -s stable --ruby
Also install Bundler: gem install bundler
Installing
Clone the repo git clone https://github.com/fdoxyz/misfans.git and move into the directory (cd misfans).
Logging is done directly to the file /var/log/misfans.log. Make sure the user running the deamon has write access to the file, if you need access or you're not sure first do sudo touch /var/log/misfans.log and then chown <YOUR_USER> /var/log/misfans.log.
Install dependencies bundle install and start the daemon with ruby daemon start. misfans is using the Daemons gem, so from within this directory you can use ruby daemon.rb status, ruby daemon.rb restart, ruby daemon.rb stop to interact with the daemon.
Once the daemon is running you should expect the fan to be triggered/enabled by a GPIO pin if the temperature rises above 72 'C and the fans will stop when the temperature falls below 55 'C.
To-Do (a lot):
- Use Daemons' argument feature for data
- Organize in a proper class & make less of a script
- Consider embedding in Docker container (ruby runtime dependency)
- Test
