Glycol Support #16
Comments
|
@thorrak When you say "modern" firmware explicitly works with glycol do you mean that with the latest version of brewpi-esp8266 there should be a way to configure things to use a glycol set up? I'd love to hear the details if that is the case. If I can just tweak things in Fermentrack that would be awesome! Mine isn't really glycol, just cold water from a corny keg in my kegerator pumped through a coil in my fermenter, but conceptually I think it is identical. |
|
@thorrak I commented over on homebrewtalk. Is there a working set up for glycol style systems? I have the exact same system as mpb above. What is "modern firmware"? I have your latest brewpi-esp8266 build running, installed through fermentrack. I am able to control the beer temperature by using the fridge constant mode, but would love to be able to run beer profiles and tune the heating and cooling better. I will need to figure out how to rebuild to decrease the min_cool_on_time as the pumped coolant cools much faster than the min_cool_on_time. |

I should also say that I am horrible at the programming side of things, but would be available to help test things. I know over on the forum you said you didn't have a way to test the hardware, but I am all set up and willing to do some testing. |

If you look at the wiki there are instruction about how to setup for
glicol.
Basicaly set to 0 pid patams and reduce the time waits for cool.
A PID setup for gicol could be considered with very long period pwm. ( 60
sec) .

lalo-uy, you mean the wiki for the BrewPiLess? |

Yes

How do you issue JSON commands to this version? |
|
As an update, I ordered myself a Stasis glycol chiller which is supposed to be delivered within the next few weeks. (Supposedly - it's a Kickstarter...) When it does, I plan on pretty quickly working on adding explicit Glycol support. |
|
Excited for the update and to see how well the Stasis works. |
|
has the stasis been shipped? Ive got my builds together and my glycol (icemaster 100) set up now, wondering if there's some testing or other way I could help out |
|
Not yet - they sent out the backer surveys two weeks ago though, so I’m hoping it will ship within the next ~6 weeks. Fingers crossed! |
|
their latest update looks like refrigerant is (at this point) 3 weeks out! So at least a light at the end of the tunnel, but probs not in your 6 week (now 4 week) window. ha! |
|
I'm still hoping their boat gets a tail...current? and my 4 week window is still accurate. 🥇 |
|
did it ever arrive? |
|
Yep! Arrived earlier this afternoon. Project for uh - quarantine. |
|
Cool. Just posted my experiences with s&is brewtech equipment and esp8266 /Fermentrack |
|
hows the quarantine investigation? looking to brew again soon, wondering if i should wait for the latest and greatest or not :) |
WELL. The short version is that the glycol chiller I got (the craft-a-brew one) was WAY too loud for me to be able to use in my apartment, so I had to sell it before I could start mucking with the controller. I'm looking at buying the Blichmann one (Supposedly it's ~45dB at two feet away which is exactly the background noise in my apartment right now) and have a few questions out to Blichmann before I pull the trigger. If they get back to me today, we might be back in business by the end of next week! That said - it would still likely be another few weeks before anything was ready, so I'd say go brew. Hopefully I'll have something before the batch after. |
|
Thats frustrating! i hope you can get one that works for you! I have the Icemaster g100, doesnt seem too loud when running but i have the luxury of more space/putting it in a closet. TBH the current setup of just using the fridge only control worked great and nailed the PID responses with this chiller, So no worries, thanks for your hard work! |
|
Good news! I just received my brand new Blichmann glycol chiller. This one doesn't have the pumps integrated, which should make developing a "glycol mode" much easier. Bad news! Someone stole the package containing the actual glycol (or FedEx misdelivered it). Between the chiller & the glycol, I'm glad that they stole the glycol - but I'm annoyed, regardless, as it means that it will be at least another week before I get to play with this thing. :( |
|
That's awful! Absent glycol the final mixture is usually mostly distilled water anyway in 4 to 1 mixture. You could play with it, just not below freezing Temps! |
|
If you have a Walmart around that's still selling "non-essentials" they have glycol in either the camping or automotive section. They sell the non toxic veriety for winterizing campers. |

Great news.

That's a really good idea, actually. I've got the distilled water coming tomorrow so I can get that set up to see what the noise level is like, at least. Unfortunately, the pump I ordered shipped in the same box as the glycol so I can't actually chill anything with it, but it will be good to know if it can live in our apartment, at least!
That's a really good idea, also! I checked out Walmart's website, and unfortunately they don't seem to have any propylene glycol in our local store. If I can't get a replacement shipment in a reasonable time, it might be worth venturing over and checking to see if their website is just out-of-date! |
|
They don't list it as propylene glycol on the site its just Marine/RV Antifreeze: (https://www.walmart.com/ip/Super-Tech-RV-Marine-Antifreeze/17179674) It is just premixed water and propylene glycol if you read the back though. That is what I'm running. |
|
Hey @chucknorris101 - Would you be willing to measure the noise level of your Icemaster if I sent you a sound meter? If so, do you have an HBT or Reddit account? This Blichmann is quieter than the Stasis, but louder than what I was hoping for. :( |
|
Sure thing! I have a hbt account that's the same handle, or ok reddit it's chucknorris10101 |

I can't help with the glycol issue but I am sort of in the same boat. I discovered this project after giving BrewPiLess a try and never being able to get it going. Got yours integrated into HomeAssistant and BrewFather with Tilt logging with nearly zero effort. |
|
I also would like to help with testing if needed. I have 3 spiked brewing conical fermenters and a 1hp glycol beer line chiller. Ultimately would love to control with fermentrack. |
|
I've got a glycol chiller and just got fermentrack setup. I've got a heat cable wrapped around my conical fermenter and then I've got a beer line chiller with glycol pumping around the fermenter chiller coil. I'm yet to wire the relays to the heater cable and chiller, but I had a couple of questions... Do I essentially set the chiller so it holds a temperature in the reservoir, then wire the recirculation pump to the the "cooler" relay? Second question what is recommend pid configuration when using glycol and a heater like this? Finally I guess this is potentially a little out of scope, but would it be possible if I used a third relay to turn the chiller off altogether if for example the temperature was at a level where there chiller isn't going to kick in for hours? I.e. the set point for the beer is 19 and the room temperature is 16 so it's only going to be using the heating? I can get my home automation system to do this if necessary, especially if I can get the temperature values for the different sensors over something like a webhook, mqtt, etc? |

Hi @thorrak Thanks for everything you've contributed, It's immensely appreciated |
Yes, but just to be clear - I'm not suggesting that you need/want to go run out and get a Spark. What I'm saying is that I need to back-port explicit glycol support into this firmware to run on an ESP. My understanding is that you can use this version of Fermentrack/BrewPi legacy firmware with Glycol, it just may not be quite as efficient at maintaining temps as you would like. I haven't personally done it, but I know there are people who have/do currently use this firmware as part of a glycol system. |
|
As far as a status update is concerned, this remains high up on the list, but I still have been distracted by two other projects and thus haven't been working on changes to the BrewPi firmware over the past few months. That said, one of those two projects is expected to wrap up shortly, which should hopefully free up some bandwidth to start working on the BrewPi firmware again soon. That said: No promises on sequencing/dates. I still don't have a glycol setup at home, so I can't make any promises. |
|
@thorrak im guessing there hasnt been too much news on glycol, im looking at dipping my toes into python/esp coding for some other automation projects at home, and would love a shot at helping out. I have tried reading through the firmware/other code but would love some pointers on where to find a few things. I can putz around and test on my system also @bassicrob if you can give me a lowdown on how you installed this to HA that would be great (unless just push target?) |
Although "modern" firmware explicitly works with Glycol, it would be good to have a version of the legacy firmware that supports it as well.
