Here’s a detail shot of the beer temperature setting graph. It completely blanked out when it went up to 46, but not when it went up to 38 overnight.

I’m very sorry to hear this!
In the log file, I see many communication errors (truncated messages) and that the communication is lost and comes back. How this resulted in the fridge setting being set to this high value, I’m not sure.

Please check that the USB cable is inserted properly and see if you get no errors with a different cable.
Can you also report which version you are running?

I recommend upgrading the firmware to the latest version:

Hopefully the beer is still drinkable. Luckily it was at the end of fermentation.

Hi Elco, thanks for the response! I’m running 0.5.2 and will update once I bottle this beer, which I’ll do in the next few days. I just reseated the USB and those errors seem to have stopped, although the log indicates that it hasn’t had that error since 09:00 yesterday.

I’ve had a few similar problems, often resulting in wild temperature swings. I’ve noticed some Serial comminication errors on my log as well. Most recently I’ve had errors that result in freezing an active fermentation. Latest batch of Porter got chilled to -5C on the third day of fermentation.

In my case a simple reboot of the pi resolves the issue and communication resumes as normal.

Is there a way to imbed an automatic reboot script if serial communications fail or a defined number of failures occur in succession? Or at the very least, the sending of an email or text message alert. If one is not continuously monitoring the web interface you’d never know these errors occur until a failed communication prompts a wild swing in temp and thus a ruined fermentation.

At this point without some type of failsafe, I’m afraid I’m going to put my brewpi to rest as its proving to be more tempermental than reliable.

@tsimpson which version were you running?

I’ll try to find where this is coming from, but any information you can give me will help me do that.

Which version of Raspbian? How long ago did you install it?

uname -a

Are you running BrewPi in docker? Which version did you have on the controller?

Up until recently, the USB communication was always reliable, unless a bad cable was used.

I fixed the WiFi instabilities in the latest release. Try switching to WiFi and version 0.5.6.

@elco This is what is returned from that command:

Linux raspberrypi 4.1.6+ #810 PREEMPT Tue Aug 18 15:19:58 BST 2015 armv6l GNU/Linux

I’m using an albeit old version:
BrewPi v0.4.3b build 0.4.3b2-0-g3de44b0, running on a Particle Photon with a V2 shield on port /dev/ttyACM0

I’m not sure what docker is nor how to answer your question about the controller.

Ah, you are running a very old version of the firmware and Raspbian! That version doesn’t even have WiFi.

Something similar to your bug has been fixed in 0.4.4 already:

That’s almost 2 years ago.

Docker runs applications in isolated containers. We built such a container for BrewPi and this makes it easier to deploy it. Instead of having to install a lot of different packages, you can just get the container.

The method for installing with docker is described here:
https://wiki.brewpi.com/getting-started/raspberry-pi-docker-install

Updating will also be easier, because you can just load a newer version of the container.

I’m not going to pursue this bug further now, because it looks like it might not occur with the latest version.

Please start with a fresh install on the pi and deploy using docker, then update to firmware 0.5.6.
If the problem still exists, I’ll give it my full attention.

@Elco
I updated using the instructions here:

I elected to update the firmware in that process and did a reboot and here is the log. clearly I did something wrong as the web interface does the script is not running. It looks like I need to update to version 5 before going to the latest firmware? Not sure how to do that.

Your version is so old that it’s better to update over USB with DFU instead of the serial protocol.
First of all, update the Raspberry Pi. A fresh reinstall is recommended. Follow this guide:
https://wiki.brewpi.com/getting-started/raspberry-pi-docker-install

Then use these commands to update the firmware:

To update over USB with docker, first trigger DFU mode:

docker run -it --name brewpi-update --privileged -v ~/brewpi-data:/data --rm brewpi/brewpi-raspbian python utils/flashDfu.py --trigger

Then run the update command:

docker run -it --name brewpi-update --privileged -v ~/brewpi-data:/data --rm brewpi/brewpi-raspbian python utils/flashDfu.py --noreset

Just to be sure, click the factory defaults button afterwards.

The LED will blink blue waiting for WiFi credentials. Once you have set those with the Particle phone app, it will download a new bootloader from the cloud. The LED will turn purple during the bootloader update and then the display will come back and you’re up and running again.

At the moment, i don’t have a way to hook up the pi via usb, so I have to use SSH. Shouldn’t I be able to do everything you are describing with that?

I went through an update of raspian and it seemed to go fine, up until I get to docker. When putting in this code:

curl -sSL https://get.docker.com | sh

I get this error message:

"Either your platform is not easily detectable or is not supported by this
installer script.
Please visit the following URL for more detailed installation instructions:

https://docs.docker.com/engine/installation/"

13

Alternatively, I am trying to update the firmware via web interface.

I downloaded version 4.4 but the instructions don’t indicated where to find this hex file nor what it is called amongst the opaque files and folders of the zip.

You are confusing some things.
You should reflash the SD card of your Raspberry Pi with the latest version of raspbian. Yes you can then use ssh to log into the Raspberry Pi afterwards. To enable ssh you can put an empty file named ‘ssh’ onto the SD card.

Please see our wiki.

To update the spark, you should connect it to the pi with USB. You can connect Spark and Pi over WiFi after updating the firmware.

Ok, so I purchased a usb to micro SD reader, reflashed the SD card with Raspian lite. Created using text edit a ssh file and a wpa_supplicant.conf file substituting my wifi network name and password.

inserted the card into the pi and launched. Wasn’t able to connect via SSH. after giving it an hr or more to boot up, I shut it down, put the SD card back on the laptop to see if I made a mistake in the conf file with the wifi. However, there is no /etc/wpa_supplicant/wpa_supplicant.conf on the sd card and the ssh file has disappeared.

I’ve spent hours at this and can’t get past the first step in the wiki.

16

I suggest that you connect a screen, keyboard and network cable to your pi insert the SD card and reboot. Fix the files on the pi.
