It would be very odd if there were not a rudimentary schematic on the listing. Dave’s note is what I would try - but there are jumpers there too.

I was typing on my mobile. Otherwise, I would have added: "Someone will undoubtedly say theirs works fine." ;) Cunningham's Law is alive and well.

Good advice from all. I will share what I learned: You can print taps with threads that will sort of work. You’re going to go through a lot of designs before you finally decide on what to keep. When you have that, use some form of metallic insert. Eventually, the plastic threaded ones will...

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. :)

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.

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...

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

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.

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

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.

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...

The initial fix is always easy. The challenge is to get everything else to work again with updated core libs.

I am not sure what unintended there, but that’s what I would consider unexpected. Not necessarily the largest bug ever, but it likely should be addressed. If you’ve ever done any work with these you probably know how perilous it is to go back later just for a small change. Libraries and...

All you have to lose is a few ounces of beer and a little time. What we get back is more info. :)

They do, but they use infrared as a Hall effect sort of thing where the others I have seen myself had a physical counter. These may be great, just never used them.

The recommended flow meters, while expensive, do not promote much foaming. Some of the less expensive ones for “coffee makers” do create more. I have never used that one specifically.

Oh, I was thinking you meant one of the original BrewPi shield prototypes. Yes, that will work. Well, using a parallel LCD requires quite a bit of circuitry. If that's what you want to do, you can look at the shield design here, which also has a schematic. That design allows both the classic...

Welcome @d_swordfish! Probably not. Early on in this project, there were many bad clones because money was to be made. Now that the Uno is "old school," the ones left seem to be the better choices. That said, I cannot guarantee it. The issue most often arises in a multi-chamber scenario, and...

15 gals!

I vaguely remember a detection method that was in use there that was fairly inconsistent. Sometimes you just have to guess what the person was thinking and try to give them a message that makes sense.
