Hi.
I think I had the same issue.
From the Web UI it looked as if it had been updated, but the FW on the Spark was not.
My guess is that you did an automatic update: sudo ~/brewpi-tools/updater.py
Try the manuell way:
cd /home/brewpi/utils
sudo python updateFirmware.py
That fixed it for me.
pi@raspberrypi:/home/brewpi/utils $ sudo python updateFirmware.py

I tried the update again, and this time it worked.
I posted above that I am very happy with the precision of th control algorythm. I realized that my fan is not running, it was connected to a seperate SSR. I rewired the fan so that it turns on when the fridge is cooling (I can not have it always on, it is too loud).
Now the behaviour changed completly:
Do you think that will stabalize? Is this due to a wrong “learning process” since the BrewPi was running without fan first? Which parameters to adjust?
I will report back in a few days to tell if there were any improvements.
@Chixxi I got it to work but I lost all my settings and changes " what a bummer" I will have to go back in and make my changes again.
Don’t worry, I have an update to 0.4.1 ready which holds a lot of improvements for the control algorithm. I would advice to revert to defaults anyway.
Is there any chance for a release of 0.4 1 today? Tomorrow we will do a new large batch and it would be nice testing it out in a real environment. Otherwise it will take some weeks before we are able to test it.
Try the updater, it was silently released last night. Just did not want to announce it before going to bed 
Hi, Just updated to 0.4.1 and my Spark Brewpi will not start (or beep) - just a white blank screen. When connecting it states on Raspberry that “Unable to connect to controller, perhaps it is disconnected or otherwise unavailable”?
I use an USB cable from the Raspberry to the Spark to power / connect.
Any thoughts on what I should do to get the Spark up and running?
Thanks
Is it still in DFU mode, blinking yellow?
I released a hotfix 1 minute ago to hopefully prevent that from happening.
If that is the case, just unplug power to reset.
If that is not the case, please send me a copy of the terminal output in a PM.
You can always restore your BrewPi by booting in mode DFU (by holding the setup button when plugging in power until it flashes yellow) and running:
sudo python /home/brewpi/utils/flashDfu.py
A darts arrow is great for pushing that button through the hole in the case.
Hi Elco,
I’ve installed the 0.4.0 and now 0.4.1 without succes. The webserver is running, but I can’t seem to program my Particle Photon. It starts flashing the firmware with flashDFU (photon blinking yellow), and tells me programming is done. But hangs when opening the serial port. Also tried the update (updateFirmware.py) too, with the same problem…

I’m using a RPi2 with a Particle Photon (got several around the house, so I tought to give it a try)
I’ve tried several times, with limited succes, and different USB cables.
Best thing I got so far is some text in the web LCD telling me “** TESTING **” or “Cannot receiveLCD text fromPython script” or “Could not receiveversion from controllerPlease (re)programyour controller”
Anything I’m doing wrong? I haven’t connected any sensors to the photon yet.
I don’t think you have the latest version of the script. Can you run the updater and make sure you are on the master release (latest commit 2 days ago).
You can verify with git log in /home/brewpi.
The latest commit should be:

Yep, that fixed it… was on an older version (3/12). Right now the LCD reads the following:

Fridge --.- --.-°C

Thanks for the fix! Any guide on what pins to use on the photon? I’m currently using arduino, but want to rebuild it with the newer hardware.
Eh… You are using flashDFU and now you say you have an Arduino?
With the core/photon, we use a OneWire bus master and an level shifter for the outputs. It is not as DIY friendly as the Arduino and we do not support direct pin OneWire anymore, only via a bus master on the Photon.
Sorry for the confusion…
My current setup is a RPi model B with an arduino board. But with the new version, I wanted to update my setup to use some stuff I had around the house (PRi 2 and Photon). As you mentioned, the photon is a b#tch to get OneWire working. Going to have a look in your shop, do you offer those things to tinker with, myself?
Congrats on the awesome work btw.
You could buy just the bare board, with display and connectors, without Photon or enclosure.
Hi,
First of all congrats for the amazing project!
two or three weeks ago i managed to install and run brewpi using a debian virtual machine. Saturday i finally got my raspberry pi 2 and run all the steps to install it. At first look everything is fine, but i noticed that something is changed, from my vm to my raspberry installation like the data under maintence / control algorithm.
Im using an arduino uno, in that way, i belive i should use the legacy branch of brewpi. Right? is th updater.py able do downgrade a fresh install? is there a way to install tight from the begining the legacy branch?
I got this message a system log and it is concerning me a bit :

Even with the controller working should i move back to legacy( taking in account that in no way i will be able to get my hands on a spark before and of january/16)?
Thanks in advance
Alessandro Sartor.
Yes, you should downgrade to the legacy branch. The instructions are posted above, under Arduino users.
Hey @Elco, I am not updated to 0.4.1 yet but am between beers and thought tonight be a good chance. I have set my controller up for remote viewing using much of what is mentioned in this thread:
I was going to run the updater but was wondering if I would have to go and reconfigure all of this stuff as well. If so, that is cool but I probably wouldn’t get myself into that tonight. Any thoughts?
Thanks!
