BrewPi Remix – What’s Old is New Again

[balrog]

I look in time to time but I’ve not had to anything with mine so I let it be.

 

[bloombrews]

Now this is way to bizarre... I updated my Router firmware, and when I tried an SD card (above posts from me) that would not start up, it is now running?
Have no clue if updating the home router did the "trick", but It seems to be so.
Can anyone tell me where the Beer Profiles are stored in which File? I want to copy my old beer profiles to this new SD card

It is really lonely on this Thread now..... Did I scare everyone away, or is the "Traffic" migrating to -

Native ESP8266 BrewPi Firmware - WiFi BrewPi, no Arduino needed! ???​

I may make an amateur stab and try the ESP8266 build, if I can not get any new BrewPiRemix to work. I gave up after multiple cards, controllers, and trying a few other "fixes". I just keep getting to the home page GUI and the Script " is starting up", forever frozen (as above)

Still wondering if ANYone, has tried to download this script, run through the setup, and have a running version up, lately ? That would tell me for sure if it is on my end, or what.

I can tell you that both threads are still active, and development on both projects is still ongoing. I spent last Sunday at a brewery working on the next round of changes to both the web interface and GUI for my BrewPi integrations, and I've had Lee pinging me about work he's been doing on his latest projects.

While I haven't done a recent BPR install myself, but I also don't have as ready access to a stream of cheap RPis given the supply chain concerns over the past year. That said, I don't think that anything major has changed recently that would have caused it to break.

@Thorrak
Please let me know, what Cooling and Heating the brewery is using. I would imagine that Glycol and a Steam Jacketed Coni, would cause the BPR"s P.I.D. algorithm to over and undershoot, like mine does.
I did just get a good SD card working with the Glycol shield option, but have not run it yet on an active brew. Not sure if the glycol option when setting up the card, would also tighten up the heating side also?
I use a 300 watt "hot rod" heater, that is used in R.V's little water heaters, and this works great. I screwed the rod into a Tri clamp adapter, and its powered with 110vac, controlled by the BPRemix. It does a great job on my 1/2 Bbl Ss Brewtech Unitank, (15 gallons) but the PID lets it overshoot by 1 to 1.5 degrees over about 7-11 minute "on" cycle.
Cooling is from a small aquarium pump, down in a 55 gallon drum of approximately 36F water, that sits inside my walk-in cooler, with hoses run out the wall, outside and over to the heat-exchanger on the unitank.

Sorry -- to be clear, I was drinking their beer while coding, not helping them ferment it. While I know there are breweries that run BrewPi-derived controllers (and Fermentrack/BPR), I can't speak to exactly what settings they use (or what hardware)

That said - If any brewery in the tri-state area is interested in tinkering with a BrewPi-derived setup, hit me up. I've said it once, and I'll say it again -- the main reason that I don't have glycol mode currently is because I don't have a rig to test it with.

This has come up before, but 300W is a lot more heat than people think. "FermWraps" are 40W, which I would argue is still quite a bit in many cases, depending on ambient temp, insulation, etc -- even with 1/2 bbl of beer to manage.

 

[balrog]

One of the biggest factors in smoothing overshoot is to "right size" your heat.

 

[gromitdj]

I was initially using a 100w personal heater from Lasko and it proved to be too much heat in my 4.2 Cubic foot fridge. So I built a 75 watt reptile heater bulb with a dimmer to turn it down.

 

[bloombrews]

Well.... I got 2 good sd cards, and I put the Raspian desktop on a third, and then attempted twice to download RPR and get this-
Am I just proned to being F'd, or what? I need a beer now.....
Here is the error -

 

[bloombrews]

Thats what I tell stranger's - I have Dubious Ownership......

 

[Thorrak]

Pretty sure @LBussy released a fix for that a few days (weeks?) ago.

 

[bloombrews]

@Thorrak , yes he did, with a command line to get the RPR to download in post #596 and 597
Thanks!
Can you tell me (or anyone else), if you run any risk of "frying" your 3-wire temperature sensor, if you mix up the wires? Or cause any damage to the Controller??
I have the DS18B20, 3 wire probes - Output lead:red (VDD) , yellow(DATA) , black(GND)
I hooked up some old sensors the the new RPRemix, and not getting any temperature number showing up on the dashboard. I do know I have to define the probes under Maintenance Panel - Device Configuration - "Read Values", but I see none of the sensors being found .
thanks again for all your help

I have toasted a couple of ds18b20s over the years by misconnection but I've never blown either an RPi or an Arduino module while messing around with the sensors. That could just be luck though - it is inadvisable to tempt fate

Cheers!

@day_trippr , or anyone Else - Can anyone tell me if I will screw up my good installed RPRemix, if I change the programming language from the default now (Python), to Ubuntu Desbian ?
I want to be able to get my BeerSmith software onto my Raspberry Pi desktop so I dont have to run up to my office every time I need to update the recipe on the fly, while in the brewhouse?
Do I have to uninstall the BPRemix, download Ubuntu onto the SD card for my desktop, THEN, download RPRemix second ? Or can I leave the RPR as is, on the card, and then change the programming language to Ubuntu?
I am great at screwing things up.......

An easier way may be to run something like Google Remote Desktop on Chromium on your Pi and on your office computer and just access Beer Smith from the Pi in the brewery. (assuming you have the Pi desktop up and aren't running headless)

Thanks Lee! Wow! There are a LOT of angry people on the chat ! Good thing it was from 2016, maybe they calmed down by now

 

[day_trippr]

lol! Riiiiiight!

 

[balrog]

You're new to the interwebz, right?

His RPi birthday, is coming up next Month !

Sometimes Life happens.
Sometimes the @Revvy 's of the HBT world kinda fade away while the @Yooper 's seem to always be there handing out advice, solace and humor in equal measure for years.
One just never knows.

@Revvy , got Me beat by 7 years here! I will have to check out his Ancient Words of Wisdom
Thank's balrog
Okay.... back to BEER talk!

@LBussy , what can cause periodic loss of connection to script (script not running)?
I never had this problem before until this latest download. I know there is a question towards the end, when loading the program, that asks if you want to add a line that will periodically look if a "reconnect" is needed. I typed yes
A couple times a day, I have to go reboot the RPi, look for the new assigned IP address (it changes every time I reboot), then type the address in Raspian browser, and it is fine again.
I thought also, that the latest versions, assign a static IP address that does not change when rebooted?

 

[Exception13]

You can alleviate this by assigning an IP to your device. Any router I've ever owned allows this.

Cheers!

[day_trippr]

Agreed, look for DHCP Address Reservation and be prepared to provide a MAC for the device.
Although that's a BS router that doesn't provide even minimal lease durations...

Cheers!

Thanks @Exception13 and @day_trippr . I logged onto my Netgear Nighthawk and figured out how to do this per your instructions.
I don't think this has anything to do with my RPRemix to keep the Script running?

 

[day_trippr]

Right, they are likely unrelated, but having to search for devices is a pita so it's still a win

Cheers!

The thing with glycol (or water) is that the loop is VERY fast - and as you have seen, PID can wind up. I did release a glycol firmwre which may be more appropriate for you. It's selectable as a "shield" type when you flash.

Here's the release notes:

https://github.com/brewpi-remix/brewpi-firmware-rmx/releases/tag/0.2.13

I just read this release! I chose "Glycol" shield when I downloaded the latest BPR version, but never changed my pin Analog Input from the existing A4 to what you are saying that - "The Glycol variant uses the I2C pinouts and must use A0 as the OneWire pin."
Could this be why my BrewPi keeps freezing up?
Here is a close up of what the graph looks like when I do a sudo reboot (the only way I know how to get it going again)
----The program froze up 3 times since yesterday, and was out of action this morning, until I rebooted again

 

[LBussy]

I honestly have no idea how you even got any readings if the OneWire is on the wrong pin.
