BrewPi Remix – What’s Old is New Again

[Nagorg]

Hey folks... I'm finally dusting off and unboxing my RaspberryPi 3 that I bought in 2017 with intentions of building a BrewPi.

Seems a lot has changed over the last 7 years. Any suggestions on how I pick back up on this? Can you save me hours of thread sorting and such by pointing me to current hardware I'll want etc..? Any good holistic guides I should read? I found https://www.brewpiremix.com/brewpi-hardware/ which seems concise enough but are there other references worth taking a look at?

I don't remember the details for what I bought back then and how its all supposed to go together. Should I use BrewPi Remix, FermenTrak or is there some other "better" path these days?

Hey folks... I'm finally dusting off and unboxing my RaspberryPi 3 that I bought in 2017 with intentions of building a BrewPi.

The strength of the BrewPi is that nothing has changed in what makes a PID a PID, and the BrewPi has always done that well. As such, the controller itself has not changed much. You can still do it with an Arduino Uno (clone.). While these cost a few bucks more than the Espressif line, their advantage lies in the person who appreciates a "large print" approach. The board is physically large, so easier to work with, it has a pin header that comes already attached, making connections simple, and is (almost) the only way a guy who does not want to or know how to solder can put a system together (with the recommended Wago-style connectors.)

With the I2C variant of the Arduino firmware, a person can create a controller with an LCD and maybe even a knob without any soldering if you source the parts well.

The downside to the Arduino is that the controller is physically attached to the Pi. This may or may not be a downside for most folks because, at some point, you have wires in and out of your fridge for something.

@Thorrak has ESP8266 and (maybe not looked) ESP32-based firmwares that work with BrewPi. These almost always require you to at least solder the pin headers on, but the main advantage is the controller will work on WiFI, letting you physically separate the controller and the Pi.

Then you get to the actual interface you use, where the choices are still mainly BrewPi Remix or Fermentrack. They behave differently but ultimately serve as the way for you to see and adjust your controller. Once set, the controllers themselves will work without the Pi and whatever software you choose.

The documentation I made is still correct. The only caveats I would give you is that you should stick with the slightly older Buster or Bullseye, as some minor changes cause errors in the install scripts. Also, stay with 32-bit variants (armhf vs arm64.) If you decide to use Fermentrack, you would want to follow John's instructions.

If you choose BPR and want to go "all in" with all of the possible features of the controller, you want an Uno because (I think this is still true) the ESP variants do not support the rotary encoder (knob), door switch and all that. While you can do this with the I2C variant of the firmware without any soldering, the cleanest way would be to use the shield (you will have to source a board from one of the hobby manufacturers.) Basically, this just makes it easier to connect all the wires and gives you a place to put the resistors and optional capacitors. There are very few for this variant, and there are mostly just a lot of pin connectors.

I do not have a BOM for this variant, but you can open the design in (free) Eagle, and export the BOM. There is also an RJ-45 on this board. You can use it without that, but what it does allow is using a regular Ethernet cable to connect all of the sensors and the door switch to a breakout board inside the fridge as a slightly cleaner option for some folks.

That's it - all the docs are still good and with the exception of "don't use the current Bookworm and stick with 32-bit," all the information is still valid.

I need to update the scripts to use Bookwork or whatever else is next, but honestly, I have more ideas than time.

 

[Nagorg]

I have to say that this stuff makes my head hurt. Probably why I've just now pulled out the hardware I bought in 2017 My trusty STC-1000 temp controller has worked for me well. But, I think I'm going to trudge forward now.

Wish me luck!

 

[LBussy]

I was just trying to give you options. Arduino and some wires, a resistor and some probes (at least one). Add a wago connector and it’s easy-peasy.

 

[Nagorg]

Add a wago connector and it’s easy-peasy.

Can you give be an example of what you mean by "wago connector"? Is this an alternate for the "Euro Style" wire connector blocks?

 

[Exception13]

WAGO

Different configurations for different jobs.

 

[LBussy]

That. Yes, it's easier than the "Euro-Style" strips. These are just levers.

Any "known" issues using the Arduino UNO R4 WiFi?

https://store.arduino.cc/collections/boards-modules/products/uno-r4-wifi

 

[day_trippr]

lolz! They really went to town on that design but the result isn't going to be capable of running BrewPi's sketch without some work (maybe a lot of work )

So... It's a good thing I bought the Arduino UNO R3 in 2017!

 

[day_trippr]

If you want to run BrewPi in 2024, yup

 

[LBussy]

If you want WiFi, use @Thorrak's ESP8266 design (without LCD or rotary encoder as I remember.). The ESP32 had more pins, but I am not sure if he released that.

ESP32 is released - at least in beta. Works perfectly.

 

[LBussy]

Your code is always in Beta - and you forgot the asterisk.

Does anyone have any suggestions for a good project box that I can use to mount both the RaspberryPi and Arduino UNO into for a "clean" controller enclosure?

Here's one along the lines of one of the originals (rotary encode, LCD, etc.: https://www.thingiverse.com/thing:3416312

Here's a Tinkercad model for one with a different approach. It assumes the Shield with the RJ45 connector to the sensors: https://www.tinkercad.com/things/bV...e=OQO2XzzCFL8nYIv74kNzq-RXCCT45xABnKP3H-0V-bA

This is the lid for that box: https://www.tinkercad.com/things/5q...e=tykUhdZZCy50V-YjLNMuXrmfWiRnl1OAYlWBzyBQ4Ro

And for some reason I have these standoffs for the LCD, I assume there's a reason: https://www.tinkercad.com/things/lx...e=D8PRtcoy36qul4Kl_kQtd2F8YcKVnbPlTBci8CLV-T8

 

[Nagorg]

I don't have a 3D printer... I guess I was hoping for something I could just buy.

Looking at something like this:
https://www.amazon.com/dp/B0B87V7QTH/

Guessing it should work just fine. But was wondering what others may have used and hoping for pics etc to get ideas.

 

[day_trippr]

Don't forget to considering connector "stick out" on all sides for both boards...

Cheers!

 

[LBussy]

I’d take that Tinkercad one as an idea of how small you could go. I just bought a couple boxes like that for some outdoor WiFi access points, the grid is nice but you may find it’s off for smaller parts.

 

[Nagorg]

the grid is nice but you may find it’s off for smaller parts.

Doesn't sound like anything that zip-ties or duct tape couldn't handle!

 

[LBussy]

Indeed not. I needed that “fine layout” and didn’t get it, so my plans were delayed by getting those zip-ties and sticky mounts. Didn’t want you to endure that tragedy.

 

[playhouse]

Just got BPR up and running to replace an Inkbird cool/heat 'dumb' controller, very neat, thanks for the work you all have put into it. I could not find an answer to this one in the documentation or forums.

How do you delete old 'Beer profiles' and old 'Beers/Previous beers'? I found the ones in /home/brewpi/data/ and deleted those, but that did not remove everything from the rest of the UI?

And some feedback on the install instructions, it would be good to call out that you need to have your Arduino attached and running with your RPi during install and explain the shields question from the install.

Finally, I use TiltPi running on a different RPi integrated into Brewfather for recording my fermentations. Does that preclude me from adding the Tilt to BPR as every time I try it fails to find it.

 

[day_trippr]

Check /var/www/html for a second BPR file root...

Cheers!

 

[playhouse]

Check /var/www/html for a second BPR file root...

Cheers!

Thank you, that was it! Would be a good adder to the UI to be able to delete profiles and beers.

 

[LBussy]

Tilt not working is a bug with current Python libs I have not had a chance to fix. I’ve been traveling a bit, but I’m headed home today so maybe …..

 

[bloombrews]

HAPPY BREWTHDAY PI ! BrewPi 11 years old already !
Thanks for taking it on, @LBussy

 

[LBussy]

In Arduino years, that's like ... 647?

 

[bloombrews]

Just checking Wiki, since I did no know... could be a LOT older!

The name Arduino comes from a café in Ivrea, Italy, where some of the project's founders used to meet. The bar was named after Arduin of Ivrea, who was the margrave of the March of Ivrea and King of Italy from 1002 to 1014.[4

Hi all! After hearing about this, I had been meaning to install this for a long time, and only recently had some time to do so. I've been using my original install up until now, which is really impressive for an SD card...
All that is to say, I tried getting this to run on the latest version of Raspberry Pi OS Lite 64-bit Bookworm, and for the most part it seems to function, up until it starts failing to load the UI and the UI says the script isn't running (happens after awhile, not immediately). Going to the brewpi, nothing is happening (as in nigh zero readout on CPU, so after attempting to restart the brewpi.service, the logs output:

Does this have to do wiith the Tilt? Note that I only restarted the service once, but it looks like it was trying to clean up as many zombies as it could find...

Also, after I had done my install, I was trying to determine what appears to be the highest version of Raspberry Pi OS people are using that's the most stable - is it Buster?

I would not go back to an older version. It’s not the OS it’s Python. Yes, you should be able to disable Tilt and get it running and I need to get a moment to merge some userland suggestions to fix the BLE work.
