I have two brewpi. One I can access from any device. The other I can access only from smartphones. Why? This one, I cant change data logging time sampling. Why?
Is this only in the cron file? I was checking around in the directories and found a cron file that had "wifichecker" in it. This was the issue that was displaying on the prompt on BrewPi page. I just don't want to delete the cron file and crash everything if there's another script that calls on it.
Are you using eth0, lo, or just on the local machine? I'd love to hear how you have it setup to run without wifi and which alterations you had to make. Since I have the monitor, keyboard, and mouse, I really don't need internet access at all.
My BrewPi just decided to stop running the script... I started a new beer profile last night and it looked like it stopped around 8:30 or 9am this morning... Can anyone make suggestions based on the attached pic of the errors showing on the log screenshot? BTW, I'm running three separate instances. Ferment1, Ferment2, & Utility. The other two scripts are not running as well.
Thanks!
I have an observation turn question.
Just wired up everything and I was testing out the probes when I noticed:
The fridge probe reacts quickly, but the beer probe reacts much slower, around 60-90 seconds slower than the fridge. Is this normal?
Was this already addressed somewhere? My google foo feels weak on this one.
Is your beer probe submerged or are they both in the air? If its submerged that explains it?
Your having the infamous dying serial port problem, are you on a PC or a RPI?
I think the most common fix for this is to keep your USB->Arduino connection as short as possible and to power the Arduino via an external power adapter rather than have it get power over USB from the RPI/PC. And keep the cable away from power cables as much as possible to prevent noise from getting onto the USB line which corrupts it and kills the link. You dont need to goto great lengths, just dont twist the cord around the RPI power cable or other wiring you have in your box.
Correct, they are both submerged.... What gives? Is that normal?
By the way, thank you so much for this thread. I know that's an understatement, but thank you so much.
you are right just male/male jumpers using them to get it all set up will set up some thing cleaner when its installed in the chamber.Those look like just male/male jumper wires. He soldered them to the jumpers on the relay. Not ideal for permanent install.
I'm running it off an old laptop running Debian. The USB/power interference may explain it. I did move things around a bit this morning and I know the cables and laptop power supply are intertwined... It's also in my garage, so I can't imagine the Vegas heat is helping it out either.
As the previous post stated, thank you for your documentation of the whole process! BTW, the link on one of the original posts to give an example of opening it outside connections is down.
Cheers!
Please excuse my ignorance but
Will this setup give you any of the programmability for timed automatic steps that you get with the stc 1000+

im working on the mutable chamber set up and im stuck on step 7.
pi@raspberrypi ~ $ sudo -u brewpi git clone https://github.com/BrewPi/brewpi-script home/brewpi/chamber1
sudo: unknown user: brewpi
sudo: unable to initialize policy plugin
thanks for all the help guys.
Only logging, steps and temperatures should continue as expected if the host pc goes down.

To those who posted recently, have the issues only been with knock off arduinos?
Maybe I'm just lucky, but I've always run mine using a sainsmart arduino UNO powered from the Raspberry Pi. I've never had an issue, except when water got into my thermowell and my sensors went bonkers.
Similar, mine runs fine once i get it going. Mine almost always goes bonkers when i shove the probe down the thermowell, im not sure if the silicone i put around it just didnt cover everything so its shorting or what but once i get the thermowell down i reboot the RPI and it all comes up fine.
Thanks that's great
So if I splurge for $69 kit I don't need to have a pc in the brew house, correct?
I just thought it was about time I thanked everyone in this thread, especially FuzzeWuzze for making it possible. I am on my second brew using brewpi so far, I am yet to taste the results of either but everything seems to be working amazingly well.
Thanks again
If you head over to the BrewPi Wiki at http://diybrewpi.wikia.com/wiki/DIYBrewPi_Wikia and check out the article I wrote for multiple chamber control you might find what you are missing.

So... based off your suggestion, I went back to clean up the cables and as I was troubleshooting and moving to a different USB port, it dawned on me that when I programmed the multiple Uno units (I'm using three generic units off Amazon...), I needed to map out the USB port...
I reconnected it to the original port, and there it was and has been running flawless since...

so i am almost done with my brewpi setup, i plan on using 4 temp probs[...]
Not sure where the logic that would hold these vales.. anyone know what pages i should start re-writing?

so i am almost done with my brewpi setup, i plan on using 4 temp probs
-- beer 1
-- beer 2
-- fridge temp
-- room temp
My problem is beer 1 works but how do i get a beer two? i would like beer 2 to rotate in the LCD display and then the on the graph show the avg between beer 1 and beer 2. this would be cool if it was an option in the admin page. Checkbox for beer prob 2 . checkbox for avg of beer 1 and 2 probs... I have no problem trying to re-write and post back some of the code changes..
