Yeah, that's what I was thinking. An easy way to let you choose how you want to control the heat. Something new with NodeRed... PID AutoTune for brewing. I'll try this out next and see what happens node-red-contrib-pid-autotune

@estricklin So, you could choose a duty cycle for temperature control? Basically, a script automatically changes between 100% and 1% duty cycle to control the on/off of the heat source. Ex. if your HLT is under temp by 10F then use the 50% duty cycle. When it gets to under 1F then use 1% duty...

Yeah, it would! I did see some homemade ideas to run propane heaters (Google searching). But I didn't see anything I would try that competes with the price (safety) of a Honeywell gas controller. I'm heading down the electric brew path; but I will add good PID control into this project list...

I'd be surprised if a PID controller couldn't give you a stable temperature. But that's not always an easy task; tuning PID controllers is a real art/science. This company built a custom module for Ignition to do that (was free, looks pay only now). But this gives you an idea to the problem of...

Okay, I'll take a look. I just got the Rpi 4 with 4G a couple days ago. So I am quite excited to get it working. Propane is not going to be a problem to automate with Igntion (the platform that I'm using). Literally, anything will work there. Do you have automated gas valve control for your...

Okay, I'll let you know how it goes. At first try, I am not looking to build an auto-hop addition device, nor a CIP (clean-in-place). This was the only homebrewtalk CIP that I found https://www.homebrewtalk.com/threads/my-new-clean-in-place-cip-setup.580652/ But a Google search for CIP home...

That is cool. Glad to hear the setup was easy. I was going to start with the Automation Direct controllers for Arduino, but I might have to change my mind to use Rpi instead...

Project page updated with screenshots, demo video, and some commercial brewery links (promo videos from the software vendor). The promo videos give a good idea at what's possible.

What do you want your automated brewery to do? Sierra Nevada and Stone Brewery use the Ignition platform. So I'm confident we can make this to work for anything we need at home. Sierra Nevada Brewing Co. Makes Ignition Its Go-To SCADA Solution Brewery Improves Efficiency in Multiple Areas with...

A simple USB to Serial cable will work, yes. I'm sure just about any type of TCP/IP device can be made to work. Ignition server runs on a computer; Windows or Linux. There is no custom hardware to buy; and the Maker Edition gives you every feature they have for free (non-commercial use). As...

It looks like yes, it does run on raspberry pi. But I don't know if the Ignition Edge is available as a free (maker edition). Installing Ignition Edge on Raspberry Pi

You should give it a try. The Maker Edition has all the protocols included. And you can learn more about the stuff at work!

The only automatiopn in my last project was the temperature sensors and heat control (solid state relays), which I also used to run the fermentation fridge. The controls would drop the heat just before boilover on the BK; because it's easy to forget that is coming up when running two batches at...

Start small, build up over time. If you go electric brewery, the natural starting point is to read temperatures and control the heat (on/off). You don't have to have a PID control for that; a simple on/off with deadband is good enough. I have automated my brewery some, then sold it. Now I'm...

I just created an open-source project to automate your brewery. The info is in this post link, ask whatever you like there. https://www.homebrewtalk.com/threads/automate-your-electric-brewery-4-testers-needed-for-open-source-project.687167/

Have you thought of using PLCs and automation software? Awesome setup. I don't know what protocols the Atlas sensor use, so not sure how to recommend there. But I also come from a PLC and automation background, so that is my bias. I had an electric brewery (self made), sold this summer, and now...

The project is a webserver (Windows or Linux) that controls your electric brewery. Get access and control from any web browser. What? I am looking for 4 volunteers to provide feedback on an open-source project to automate your home brewery. Contact If this seems interesting to you, PM me and I...
