BrewPi Remix – What’s Old is New Again

[aeklo]

Try a reboot - because you never know. Then have a look again. Sometimes it will throw an error starting up so the error log is harmless. The real question is whether or not you ever get a display in the header.

Sorry I was bothering you with this one. A reboot did indeed fix it! All seems good now.
Thanks again for sorting this out, and happy holidays

It's no problem. A reboot should not be needed, but it works sometimes. I've been chasing that particular gremlin for a little while. "One of these days ... "

I'm glad you got it running (and I'm glad I'm not the only one awake this early.)

I may be having a personal problem... looking into it further. I do have a non-standard install kludged up into a docker container. So this may not be code issues... i'll confirm if i figure it out. But after trying the update script as well as a fresh rebuild I'm seeing crazy spacing on the banner that was converted to css. The previous 0.5.x version worked fine.

here is what my header looks like:

well I do have this huge header on iphone Safari. I am trying to investigate as some browsers on my computers look fine but firefox on my laptop does not. I will try the ublock origin toggle trick. I am confused about safari though. Any ideas?

On your update the script tries at some point to flash arduino? That gave a fail message but it went through and everything works as it should. I needed some file that did not exist. I am sorry i don't have screenshot to help you out.

Interesting. Let me un-screw my local install and I'll take a look.

Yep, noticed that this morning. In the meantime you can flash a controller with:

sudo /home/brewpi/utils/updateFirmware.py

Absolutely not - and the default there is "No", but it's available.

That workflow may change, not sure.

I use FireFox for 99% of my work on both my (Windows) laptop and my iPhone. The header obviously renders correctly for me. Here it is in Safari, landscape and portrait, from my phone:

There are a few addons I can think of which may impact the layout:

• AdBlock
• Privacy Badger
• uBlock Origin
• ... probably more. Anything that promises to make you safer.

There's no good reason for any of these to interfere (and I use a couple of them.) The problem is often that if a plugin doesn't if it's safe, it assumes it is not. There's nothing about BrewPi Remix which is dangerous, and it doesn't even use very common Content Managament-based source files, preferring a local version.

I have Windows and iOS devices and I test with the following browsers on each:

• Chrome
• Firefox
• Safari
• Internet Explorer (Windows)
• Edge (Windows)

If you can reproduce it consistently, try again in safe mode which should disable all extensions. If it works properly a that point, add them back in one at a time to see which one does it.

Just another thought.. since toggling ublock on my system "fixed" it then it's likely due to a caching issue. My browser likely remembered/cached part of that page from the previous non-css setup and mixed/mingled it.

Try wiping/refreshing cache on any devices that are having weird headers.

Ah yes, good point. Shift-refresh has become just the way I work since developing these pages. Using private mode will do the same thing on an iPhone. I assume something similar exists for Android.

BrewPi Remix Feature/Bug Release 0.7.0

When I decided to embrace semantic versioning, I knew I would have strange choices to make. I did not realize that it would be the very next release that caused my issues. While to the end-user, this release may seem more of a bug fix, on the inside this is a significant/feature release.

The most important aspect of this release is moving the Python3 pip environment to a venv and requirements.txt format rather than the original root install. The effect should be a much more stable environment and less potential impact from other packages and solutions.

Upgrading

Existing users of BrewPi Remix 0.5.3 and above may upgrade with:

sudo /home/brewpi/utils/doUpdate.sh

If you are not on version 0.5.3 or above (or if you have no idea what version you are on,) use the following command to upgrade to the latest version:

curl -L upgrade.brewpiremix.com | sudo bash

This must be run from within your /home/brewpi directory, or from each chamber directory in multi-chamber mode.

Combined Release

This release includes several changes across the repositories. Notable among these are:

Tools

• Fix udev setup for multi-chamber installations
• Skip flashing controller if none was detected during multi-chamber setup
• Support Python3 venv setup

Scripts

• Address logging errors/choices
• Use Python3 venv setup. The venv must be activated if for some reason you wish to execute BrewPi or its Python tools from the command line. Execute . /home/brewpi/venv/bin/activate (pay attention to the leading ".") to activate the venv (or as user brewpi, you can just issue the command activate.) To deactivate, type deactivate.
• Increase temp and SG resolution displayed on Tilt Pro
• Add config items to clamp SG and temp values displayed. These can be set in the config.cfg and need to be entered in the current temperature format.
• Move to public aioblescan library and re-write Tilt.py.

WWW

• Re-format multi-index layout to match the functionality of the chamber index
• Increase temp and SG resolution displayed on Tilt Pro
• Externalize some common code blocks

One Release, Three Parts

As always: BrewPi Remix, like BrewPi before it, is made up of several different packages. Therefore, it is in separate GitHub repositories. The scripts I have provided abstract much of this from the end-user, but sometimes it is important to know.

Thank you!

Thank you to @bloombrews who pointed out an issue with the multi-chamber setup.

 

[FuzzeWuzze]

In on new thread. Nothing of importance to add to the conversation, keep up the good work

Just a little update: I am switching name registrars, DNS and web hosts so I am SURE I will screw that up somewhere.

If you notice any issues getting to any of the hosted or DNS options, post here.

0.7.2 Bugfix Release

This release addresses the following:

• Clone all branches of a repo on install to allow switching between branches
• Addresses a condition where users with a Tilt configured, but no Tilt present would experience a crash
• Addresses a condition where Tiltbridge sending a NULL packet would crash the script

I'm also addressing an issue where the 0,7.0 tag was not applied correctly in the repos, which will result in a large number of changes seemingly part of this release.

Upgrading

Existing users of BrewPi Remix 0.5.3 and above may upgrade with:

sudo /home/brewpi/utils/doUpdate.sh

If you are not on version 0.5.3 or above (or if you have no idea what version you are on,) use the following command to upgrade to the latest version:

curl -L upgrade.brewpiremix.com | sudo bash

This must be run from within your /home/brewpi directory, or from each chamber directory in multi-chamber mode.

"Hey Lee, what about release 0.7.1??!"

... that's not important right now.

 

[day_trippr]

What's the command for a new installation?

[If I can ever finish up converting all of the peecees in the house to Windows 10 Pro I will get to ^this^]

Cheers!

What's the command for a new installation?

Why, it's easy!

Hi, I've been using an old brewpi for a few years. Thinking that one day I might have problems, I have searched for update information until I reached this thread. I also found threads about brewpisless and fermentrack. I am not very clear about the direction to follow and I wonder if I could guide myself with the basic doubts to follow one path or another. I do not extend myself further in case this is not the right place for these queries, if you think that this question should go elsewhere I will be happy to do it where you indicate. I thank you in advance for your attention.

[LBussy]

Welcome to the thread!

While derived from the original BrewPi, both Fermentrack and BrewPiLess are rightfully different products. BrewPi Remix is very close to the original and would feel most familiar to you.

While there are ways to "upgrade" I would caution against that. As a matter of fact, if you have an older installation I would suggest starting with a fresh version of the operating system as well. If you've forgotten how the Raspbian website has very good step by step instructions.

Keep in mind you will lose your old brew charts and anything else you have on your Pi. Unless those are important to you for some reason, BrewPi will not need them. You could also get a new SD card and start with that if you want to keep the old one for any reason.

Once you have Pi up and running, all you need to do is enter the following line in the terminal:

curl -L install.brewpiremix.com | sudo bash

That will guide you through the installation.

There's no immediate need to upgrade your Arduino, and that will help ensure your devices stay set up correctly. If it's very old that might go sideways, so please feel free to post here with any issues.

 

[blau]

Thanks for your interest. I extend myself a bit to better guide my position.
- Now my equipment is working correctly with a raspberri pi b + and 1 arduino uno. The operation is stable and I have a backup copy of the sd saved on my pc.
- With the system working, I think I could invest in a new team, work on it and once configured, use the old one for something different or to have a backup in case of disaster.
The first doubts are:
- I see the current team has a clock lag. When I do a fermentation I am careful to correctly update the time and check it if I have to make adjustments in long programs (lager). Is this still a problem or can new computers update the time via the internet?
- My team is not in my house. To check it I have to connect through another pc connected to the brewpi network through teamviewer (or vnc, anydesk ... etc). I should be able to install some of these software directly on the raspberry but I have not succeeded, I am inexperienced and the error messages I could not decrypt. I thought the system was too small and this is one of the reasons to think of a new raspberry. I'm right? What board and minimum memory would I need?
- Another reason for updating would be to also control 2 other freezers in which I do the rest of the processes. I saw a long time ago that I could do this with brewpi but users reported problems and I did not want risks. Today these other equipments work with 2 thermostats. I see that both brewpi remix and fermentrack manage different teams with a single Pi, but I can't see the difference between them to choose one path. Although fermentrack seems modern and uncluttered, the classic look of brewpi remix is not a bother for me, what is the strength of each one to decide what to install?
Well, I think that when I clear up these first questions, I can keep thinking about the next ones. So this does not become eternal.
By the way, excuse my English. I have to help myself with google to write well from my Spanish.

I use a Pi 2B for testing. The Zero W works as well. That said, these are not expensive computers and many things are more enjoyable with a little more. I'd recommend the 3B+ as a basis for these projects, just because having the WiFi and Bluetooth on the board is easier, and after all, faster is faster, right?

I see the current team has a clock lag. When I do a fermentation I am careful to correctly update the time and check it if I have to make adjustments in long programs (lager). Is this still a problem or can new computers update the time via the internet?

If you set the timezone in raspi-config, it should update on boot. There are two choices to keep it synching, either ntp or systemd timesyncd. Check both of the following and see which one is running:

sudo systemctl status ntp

or

sudo systemctl start systemd-timesyncd

When you figure out which one, a little Googling should help figure out what's going wrong, or you can tell us what you find.

Yes, BrewPi Remix can do this (as well as others). You still need a controller per chamber (but only one Pi.)

Although fermentrack seems modern and uncluttered, the classic look of brewpi remix is not a bother for me, what is the strength of each one to decide what to install?

I am biased of course, but I am pretty familiar with both. Fermentrak and BrewPi Remix will use the same controllers, so it is ultimately about which interface you prefer. BrewPi Remix will treat each chamber separately (although on the same Pi) and Fermentrack uses a completely different system.

Both systems will also run on the same Pi although you would need to install Fermentrack first and then BrewPI Remix, as otherwise, Fermentrack will clobber the installation.

-- Ok, I'm going to check prices. like you say, it's not a lot of money. Even between 3+ and 4 is little difference. I study it and start by buying one of them. As soon as the investment is made there is no going back.

-- I had seen your collaboration with Fermentrak, and this helps to ask about both. It is important to try not to offend those who offer their work for free. The first idea was to buy two sd cards (today also its price is accessible and I can use it for something else) but perhaps a first basic installation of the two things will allow me a quick comparison. I already have new tasks to do. It's my fault for asking ... Thanks, I promise to keep bothering you.

 

[LBussy]

It's no trouble at all. Yes, having two SD cards is the simplest way to experiment.

 

[blau]

Hello, Regarding the relays, I think I will use ssr. I have them in my current installation and although they may not be necessary they give me more peace of mind to act with the freezer compressors. Regarding the new equipment that will replace the arduino uno, if I need a recommendation. I see: NodeMcu, ESP 12E, ESP 32, ESP 12 MINI ... etc, can you put light on this? And about its consumption? I still have to think if I'm going to feed them individually or a feeder for the 3 that I'm going to use (I think the "Uno" from the old equipment will be used with the rest of that system for testing.) Thanks.

 

[LBussy]

Your current choices are the Uno and the ESP8266 (generally the Wemos D1 Mini is used). The ESP8266 is, of course, WiFi capable, however, some soldering is necessary. It's easiest with one of the shields (the design for which is in the GitHub repos). The Uno can be done from start to finish without soldering, even with a rotary encoder and LCD. The ESSP8266 does not support the rotary encoder. You can make the Uno wireless either with WiFi or Bluetooth with some added hardware.

Most people would recommend that you supply power independently no matter what, but I run two Unos from my Pi with no apparent issues.

The SSR is fine, they have to be set up as "non-inverted" with a slightly different wiring configuration.

Hello, I have added the ESP8266 to my shopping cart, soldering is not a problem for me. As for the Rotary, I have never really liked it. An ldc if it could be necessary, I still doubt, the price is low. Do you need extra hardware or programming or just plug it in? Any specific model?.
by the way, can you upload some screenshots to see how the different cameras are chosen? or is it another browser tab with another address all in duplicate?
Thanks again.

Of course, I will try again.
- The Rotary switch is not interesting to me. I prefer to change the parameters with the brewpi console. Even so, I think it would be good to install a display for each of the cold rooms. To be able to see the data of the moment while I do other things in my place. I see that now the displays are very cheap. If the installation does not complicate the system I would install it. If this generates, or can generate problems, it is a hardware that I can do without. Can you tell me the generic model of the display to find a correct one?
- I don't understand how I can see the data of the different refrigerators on my screen. Each camera has an IP address to open a browser tab with a browser (refrigerator 1, refrigerator2 ... etc), or do we have, on the main screen, any button or selector to switch between refrigerators?
I asked him for some capture of this, if your team moves several refrigerators.
If it is not understood say it, I will reformulate the question as many times as necessary.
Thanks.

 

[LBussy]

I think I understand now.

When we say "display" of course there are two different methods. There is the LCD attached to the controller and the web user interface. If you mean the LCD, you need a 20x4 LCD with an I2C connection. Something like this.

For the web UI, there is an index page where the status of each chamber is displayed:

You can click on one to go to the familiar page for a more detailed view.

Is that what you meant?

Good Morning,
Now yes. The answers have been precise. I'm going to check that lcd screen, does it need extra code or is it plug and play? a simple switch on its power supply to turn it off when not necessary? P.S. I'm starting to wonder if I'm going to try "Fermentrack" ;-)
