I’m using my brewpi to control a fan in a Son of Fermentation Chiller setup. In my test runs I was able to bring ambient temperatures down to about 15C.
I haven’t added warming yet, so at night the chamber temp gets lower than it should. For now I can just work on tuning the cooling. One change I attempted is setting minimum rest and activation times to 0 since I’m not running a compressor.
Here’s a log of the first 24 hours or so of my current brew.

I am getting ready to test run my own SoF chiller. The beer chamber is about 50% longer than the official plans so I am expecting the chamber not to be so efficient with more frequent ice changes. This is so I can fit an extra carboy. All I have done so far is construct the chiller and get the brew pi to turn on a fan based on ambient temperature but have yet to marry the two projects together.
For device configuration, should I have the cooling method be listed as a fan or as a fridge cooler? I am using a 12v dc fan that will be controlled by the brewpi arduino, no compressor whatsoever.
Jkyle, did you ever add a heating element to your chiller or did you go with something like a heat wrap? Did it work for you? I was thinking of not having a heating element at all given the flammable nature of foam insulation.
