Chillmon is our Raspberry Pi powered system for maintaining the proper temperature in the Beer Church fermentation chamber. It interfaces to IRC, like so:

   <+Toba> !temp
   < chillmon> temperatures: beertop: 67.9 F, beer: 68.5 F, room: 64.4 F   

Interfaces

There's a web interface running on Bellamy that shows the PID controller state history.

• http://10.100.0.106:8008/
• You can get a stream of JSON objects over ZeroMQ that might interest you from tcp://10.100.1.76:7000 if you know how to do that.
• Chillmon's irc interface should be workin' right now.

Hardware

AC Unit

Wiring: green ground, white common, red fan, thicker red AC chiller.

RPi

• Mac: b8:27:eb:fd:d5:a4
• IP (maybe): 10.100.1.76
• Username: pi

To find the IP if that IP isn't working, use:

   eastein@bowmore ~ :) $ sudo arp-scan -R --interface wlan0 --localnet | grep -i b8:27:eb:fd:d5:a4
   [sudo] password for eastein: 
   10.100.1.76	b8:27:eb:fd:d5:a4	(Unknown)

If you don't use linux, I'm sorry that you are trying to do useful things with your computer, but I can't help you.

The screen session containing the chillmon process starts up at reboot on the Pi using vixie cron's @reboot in the pi user's user-crontab.
