hi all. i have a diy brewpi i made awhile back but never got around to using.
the other day i decided to make a sour and planned to use the brewpi as the temp controller for souring.
i decided to run a quick test to see if my heat source could keep up, and all seemed to go well for about 2 days. Then the strange thing happened. I got home from work and noticed the brewpi stopped working at about midday.
It said the script was running and displayed the beer and fridge set values, but not the actual beer/fridge temps. It also didnt seem to be heating anymore.
I gave it a quick disconnect from the usb (running wheazy on an old laptop) and it seemed to be back to normal for the few hours before i went to bed.
This morning when i woke up i checked it again and it had began the same behavior of not working again right after i fell asleep last night.
upon checking the logs i got the following:
warning 2 temperature sensor disconnected from pin 18 address.....
info message 0 temp sensor connected pin 18 address... (same address
tried to reboot again to no avail
checked logs again and see
Arduino debug message: INFO MESSAGE 19: No peak detected. Drifting up after heating, current temp: 83.9, estimated peak: 118.4. Previous heat estimator: 0.004, New heat estimator: 0.002..
if i stop the script and restart it
Traceback (most recent call last):

Mar 29 2016 09:47:13 Found BrewPi v0.2.4, running commit 2a6f7f05
build 40, on an Arduino standard with a revC shield on port /dev/ttyACM0
Mar 29 2016 17:22:02 Error opening alternative serial port: could not open port /dev/ttyACM1: [Errno 2] No such file or directory: '/dev/ttyACM1'. Script will exit.
Mar 29 2016 17:23:02 Error opening serial port: could not open port /dev/ttyACM0: [Errno 19] No such device: '/dev/ttyACM0'. Trying alternative serial port /dev/ttyACM1.
at this point im not even sure if my issue is hardware or software, or even where to begin.
i'm tempted to do a wipe of brewpi and install via the new install instuctions (i built this one about a year ago) however i'm not linux savvy and had a hell of a time getting the drivers for the laptop im using installed and REALLY dont want to have to go through that again.
anyone have any helpful advice?
thanks in advance, and i'll owe ya a beer
