BrewPi Spark v2 upgrade Firmware issues

I have a BrewPi Spark v2 and it has run solid for a couple years. I had some time to work on bringing it up to date and have ran into issues. I have spent several hours looking through the forum and have been able to get things working but am unable to fix a couple issues.

  1. I am unable to update the Brewpi firmware from version 0.4.2 to version 0.5.4 (described below)
  2. The error log repeatedly is getting the following error: Error: Received invalid message on socket: lcd

I am most concerned with getting the BrewPi all up-to-date and then maybe that will fix my second issue.

When I try to manually update my BrewPi using the following commands over SSH connection

cd brewpi-tools/
sudo python --ask

It doesn’t matter which upgrade firmware option I pick I get the same error?

In the BrewPi Error log through the Web interface I get the following compatibility error.

Please Help! How do I get the Firmware updated to version 0.5.4?


Why did you choose 11?

If you run ‘git log’ in /home/brewpi, does it show recent commits?
You can try to run a ‘git pull’ instead of running the update script.

Thanks for the quick reply Elco.

I chose 11 because I thought I might need to upgrade in order. I had tried 0.5.4 and 0.5.2 and had the same issue. So I tried 0.4.3 on this attempt. That is the only reason why I chose 11.

I tried the ‘git log’ and doesn’t seem to have anything recent.

I tried ‘git pull’ and it return this.

pi@raspberrypi /home/brewpi $ git pull
Already up-to-date.


The last commit on master is from March 18:

I think you have the release/0.5.0 branch checked out. The last commit on that is from that date.

Please run git checkout master and then do a git pull.

If that doesn’t help, what does git remote -v show? Do you have the right github repository as remote (BrewPi/brewpi-script)?

Here is my results from running the commands you requested.

I have already installed the latest Master Script. I am looking upgrade my firmware. Does the ‘git pull’ command pull Brewpi firmware updates too?

Thanks for your help Elco! I really appreciate it. I have been very impressed with the BrewPi and feel it has been a vital part of my success in winning many awards for the beers I developed and fermented in my controlled fermentation chamber. With all the success it has lead me to an opportunity to partner with a couple guys and open a Brewery in my home town. I absolutely love the ability to keep an eye on fermentation remotely at all times and make adjustments if needed. The BrewPi is an excellent product!

pi@raspberrypi ~ $ cd /home/brewpi

Try running git log again. I think you’ll have a newer version now.

Hi Elco,
I want to use my BrewPi Spark v2 for controlling my existing fermentation chamber, and to control mash temperature. I got a few questions on this

  1. If you reprogram the Particle Photon, does this mean changing the device configuration?
  2. Where do you save a device configuration?
  3. How many temperatures can be controlled?
  4. Sometimes my BrewPI Spark looses it’s IP address. There is app. 10 m between my WIFI router to my BrewPI, but through a brick wall and a few inner walls?

BR Ken

Here is my out put from the git log now. I only posted items from 2018 that now show up.

Thank you,

reliability updates for ymodem

I would like to upgrade my spark v2 brewpi to the latest docker-based version. Is there an upgrade guide somehwere? Not sure how I should go about “tearing down” the current installation and moving to the current one. I would appreciate any pointers! thx.

We’ll be releasing the beta of the Big Upgrade soon, so unless you are planning to brew this weekend I would postpone to avoid double work.

Thanks for the heads-up! Then I will wait for the upgrade. If you would like me to test the beta, I’d be happy to. Is there any way I can be informed when the release is ready - is there a newsletter or something?


For the very first beta release, I won’t do a big announcement just yet. I will just post it here on the forum for our most adventurous users to try.
