Hey, thanks. Are these the actual commands?
sudo apt-get update
sudo apt-get upgrade
My Rpi came with two little heatsinks for two of the chips, I suppose. Are you guys putting them on?
Run sudo update the run sudo upgrade then try the install script again.
On my BrewPi, connected via ssh, if I paste this into a text document named gettemp.py, save, exit and run:
python gettemp.py
it will return
["Mode Beer Profile ", "Beer 50.5 50.0 °F", "Fridge 41.8 39.9 °F", "Wait to Cool 00m31"]
So disappointing. I bought a 10 pack of phono jacks to make up my temp probe connectors. They are literally the worst quality I've ever seen. 2 of them have stripped jackets and I just pulled them from the bubble wrap. Stupid Chinese crap!

I purchased most of the items in FuzzeWuzze's original post. I also purchased the rev c shield from BrewPi.com because I wanted a display. Everything seems to be working ok with the exception of the backlight on the display.
My understanding is that if you press or rotate the rotary encoder, the backlight will come on making the display easier to read. As it is now, the display is almost unreadable.
If I apply voltage to pin 15 on the display, the backlight works fine.
Is this a problem with the shield or a software problem? Any ideas?
Yeah I was totally looking forward to doing this for 5 bucks instead of 40

Go big or go home.

I have the BrewPi shield and I don't recall a backlight pot. There is a contrast pot that needs to be adjusted, but not one for the backlight. Because the backlight eventually turns off (roughly after about ten minutes of inactivity from the encoder), I would guess that Elco has one of the Arduino pins driving the backlight. If you are not getting the backlight to work, there might be an issue with the connection between the shield and the display. If you have found that 5V to pin 15 is lighting up the backlight LED, there must be a problem with the connection on the shield to the Arduino pin that drives the backlight. The problem is either in the connection to the shield, or in the ribbon cable from the shield to the LCD display board. You could in theory test this by uploading your own sketch to the Arduino that turns that pin on the Arduino to high. If this works, then there is a software issue. I suspect it's likely a hardware problem. You might want to contact Elco about this since it is not an issue with the LCD itself.

Here's my fermentation chamber controlled for a week now using my BrewPi. I just have one carboy fermenting a Dopplesticke Altbier that I brewed last Saturday. Yeast is WLP036, and I'm fermenting at 57F for 8 days before I kick it up to 68 for a 2 day diacetyl rest, and then cold crash it.
Looking at the fridge temp sawtooth plot I thought it looked wicked active, but on closer examination it's averaging only ~13 cycles in a 24 hour period, so it's not actually working the compressor that hard at all.
Very encouraging. I'm in the midst of cobbling together my new keezer control/monitoring system and intend to have BrewPi run it, with an MH1210 as backup if things go pear shaped. My keezer cycles around 7 times per day and would like to keep it in the ballpark of that lazy level...
Cheers!
I found these nice 12mm three pole aviation plugs on ebay that look like they are good quality for a great price.
As a matter of fact, while I was posting this I decided to purchase some. 10 sets for $10.16 delivered. I may not get them till December but I'll have them for future projects.
