[Version 2 Release] RaspberryPints - Digital Taplist Solution

I just got a Ferment track setup working last night.

How do I go about installing Raspberry Pints on my 3b+ running Stretch? I don't have flowmeters now, but would like to add them at some point.

I know there have been some serious improvements made since I tried and failed at installing RPints a while back.

 

There are two main ways to install:
Follow Day_tripprs: http://www.homebrewtalk.com/showpost.php?p=8040187&postcount=2643 to install the original
or
My installation script: https://www.homebrewtalk.com/forum/...-taplist-solution.487694/page-96#post-8457261 to install my version which has some new functionality in it.

 

Great, thank you!

 

Both tests with establishContact at 1000
If my baud rate is 9600, I get an endless loop of:

[email protected]:~ $ tail -f /var/log/rpints.log
2019-03-11 15:03:22 RPINTS: waiting for alamode to come alive

2019-03-11 15:03:29 RPINTS: serial connection stopped...
2019-03-11 15:03:30 RPINTS: flowmonitor aborted, restarting...​

If my baud rate is 57600, I get this without any looping:

2019-03-11 15:21:33 RPINTS: Could not import RFID Reader, RFID disabled. Assuming SPI not installed/configured

2019-03-11 15:21:36 RPINTS: waiting for alamode to come alive​

I ran both tests with the establishContact at 100 and got the added error of "serial connection stopped..." on the 57600 baud rate setting.

 

My guess is that the Uno is still sending the Alive message to fast for the python to process at 9600
And at 57600 its not making contact with the python to trigger the restart, but that doenst make sense if a delay of 100 generates more log.

did you try delay of 5000?

 

With both a 5 second delay and a 10 second delay I get the same results at 57600 baud:

I ran your RandR+ installation script last night. Something went wrong with the installation of Apache2. I cannot start Apache2, therefore RPints doesn’t work.

Now, I had already installed Fermentrack on this Raspberry Pi and had installed the legacy support for programs like RPints. Is it possible that this screwed up the Apache2 installation? Should I wipe the SD card and install RPints first followed by Fermentrack?

 

My thought is that the python is only looking for 9600 baud so the 57600 from the Uno is not allowing it to connect. You can try changing the python to 57600 also by changing line ~214 of python/FlowMonitor.py from
self.arduino = serial.Serial(self.port,9600,timeout=.5)
to
self.arduino = serial.Serial(self.port,57600,timeout=.5)

 

I tried to install Fermentrack on a test system with RPints installed already and it failed on nginx installation.

Since nginx is a webserver it makes sense that both nginx and apache cannot run on the same machine by default because they try to use the same port.

Fermentrack has a support article about this: http://docs.fermentrack.com/en/master/getting started/Apache and PHP Support.html?highlight=apache

 

@RandR+ Thanks for the suggestions. If I do that I get a loop of:

[email protected]:~ $ tail -f /var/log/rpints.log
2019-03-12 20:58:53 RPINTS: waiting for alamode to come alive
2019-03-12 20:58:54 RPINTS: serial connection stopped...

2019-03-12 20:58:57 RPINTS: flowmonitor aborted, restarting...
2019-03-12 20:58:57 RPINTS: resetting alamode
​

In Arduion IDE Serial Monitor with flowmon stopped, I still get:

alive
alive
alive
C:4:2:10:11:12:0:300:35:30:250:0:0|
StatusCheck;
U;-1;11;251
P;-1;11;499​

 

So the Uno code is working based on the serial monitor output, now to get the flowmon service going.

did you change python/Config.py lines ~13 and 16 removing False# to leave just
config['xxxxx.debug' ] = True
?

The log should change and give more details as to what is going on.

 

The tests yesterday were with establishContact at 1000 and just line 13 flowmon debug = True. Adding dispatch debug = True I get this with all baud rates (flowmon.py & raspberrypints.ino) at 57600 I get this looped:

That is my error that is stopping your system.

Someone else ran into an issue with some calls that were changed from python 2 to 3 when running on Jessie. I tried to add smarts to call the correct function based on version, the problem was I somehow committed the wrong call to check the version.

I just committed the fix, update python/FlowMonitor.py from GIT or just replace all reference of system_info with version_info in FlowMonitor.py

​

 

@RandR+ Sir, I'm humbled by your generosity of time and talent. IT WORKS!! Thank you!
I'm going to reload just Stretch with desktop instead of NOOBs as I loaded NOOBs to see if a driver (or something) was missing. Again, THANKS.

 

Next week or so is looking like a kick-fest here.
First soldier down, 10 past zero. I can live with that



Cheers!

 

Not that I doubt your abilities, but it looks like you are going to need help with that Kolsch. I'm here if you need me.

 

In honor of Pi Day tomorrow, I'd like to share how I've gotten RaspberryPints and flow meters operational on a Raspberry Pi 3B+ and Clone Arduino UNO R3. What worked for me is:

1. used balenaEtcher and latest Raspbian Stretch with Desktop and recommended software written to a 64gb microSD on Win10 PC
2. updated all programs on first boot of Raspbery Pi
3. used @RandR+ fantastic install script, just cut and paste from lines 14, 18, & 20 and say "yes" when asked about configuring initial database:
4. found MAC address of RPi in Terminal: ifconfig eth0
5. updated home router for a static IP address
6. Terminal: sudo /etc/init.d/flowmon stop
7. Terminal to kill hex file: sudo mv /var/www/html/arduino/raspberrypints/raspberrypints.cpp.hex /var/www/html/arduino/raspberrypints/raspberrypints.cpp.hex.save
8. Terminal: sudo nano /var/www/html/python/Config.py (open the window to full page) the last line should be: config['flowmon.port'] = '/dev/ttyAMC0' (mine was set at /dev/ttySO) if this is not the last line, go up and remove the ## from the beginning of it
9. Arduino IDE: Tools Tab: Board: Arduino UNO, Serial Port: /dev/ttyACM0.
10. Arduino IDE: Sketch Tab: Add File: Choose file system on left panel: var/www/html/arduino/raspberrypints/raspberrypints.ino "Open"
    
11. Arduino IDE: find "establishContact" and change the timing from (100) to (500)
12. Terminal: sudo /etc/init.d/flowmon start
    
13. Chromium: log into rPints using the static IP address established earlier, click on the "Your Logo Here" to get to the configurations page

When using Terminal, "^" is the Ctrl key. When in "sudo nano" you can search for specific text like "establishContact" using "^W", save your changes using "^O" ("Enter" key to overwrite existing file) and exit using "^X" The up/down/left/right arrow keys are the only other way I know to move around in the program lines. Thanks to all who have contributed to this forum! I hope this helps others get through the learning curve a little quicker.

 

Hi all. Does anyone know if i can control my pi desktop via vnc from an outside network?
I've currently set up noip and can connect to my pi from anywhere but i can only see the Raspberrypints screen which is great for now showing off which beers i have on tap but i'd like to be able to open another web page at least so i can log into my router.

Any ideas?

 

Any progress on this @kaljade ?
I totally understand if you havent got the time off course. Just wondering.

Regards BB

 

I was coming here to post my recent developments and saw this. I went to install fermentrack on my working Stretch RPints w/ flowmeters using Uno hard wired using Rand's script. Well i dont think Fermentrack works on stretch for the same reason RPints didnt before all this work because PHP5 ins available on stretch. Thorrak is aware but idk what he plans to do. Would be nice to have both Rand's RPints and ferment track to be installed easily with their 2 scripts. So for the time being i just installed fermentrack on another RPi with Jessie.

Which i ran into another issue. Does teamviewer not work with jessie? I downloaded the RPi temviewer installer and it isnt working? I thought it might be cause it is the Stretch version but i cant find a Jessie specific version. Doesn anyone have a link?

 

Fermentrack and RaspberryPints don't work well together because of the Apache vs. NGINX differences, not because Fermentrack doesn't work on Stretch. I did a clean install of Fermentrack on a new Stretch install the other day and it was flawless. Give it a try again with a new install of Stretch.

 

you did a lot more than what i had to do i didnt have to do steps 6-12. Here are my documented steps for installing the script and changing from alamode to Uno.

Setup Static IP
https://www.homebrewtalk.com/forum/...-taplist-solution.487694/page-72#post-8087858
edit

Code:

sudo nano /etc/dhcpcd.conf

Add these lines to the bottom of the page
use the ip you want and your routers address

RandR+ Install
https://www.homebrewtalk.com/forum/...-taplist-solution.487694/page-96#post-8470336
download
https://raw.githubusercontent.com/rtlindne/RaspberryPints/master/util/installRaspberryPints
to
/home/pi
run

Code:

chmod +x installRaspberryPints

Code:

 sudo ./installRaspberryPints

whole process will take a while
With RandR's script, if not using an alamode you need to edit the config.py to turn on the UNO

Code:

sudo nano /var/www/html/python/Config.py

Add a # to the Alamode line and remove the # on the UNO/USB line

To see if the Uno is getting recognized
Run

Code:

sudo nano /var/www/html/python/Config.py

edit to
#logging settings for flowmon
config['flowmon.debug' ] = True

then you can look at the /var/log/rpints.log to see if it loads OK. and revert back to False#True




I did find that a Uno Clone does not get recognized. Im assuming i would have to go fine the code change in this thread and edit that to get a Uno Clone to work.

 

yea i know the Apache NGinx difference but Thorrack mentioned something about PHP5 not being available on stretch and Rand has to "create" PHP7. Like i said i know none of this but here is the conversation over in the fermentrack thread. I will try to install it on stretch tonight.

I hope my post didn't come off as prick-ish. It certainly wasn't meant to. I don't know much more than you do, I'm only trying to make sure there isn't any unnecessary confusion for folks coming along after.

 

Lol, yeah so much life got in the way since then:

I took a redundancy from my previous employer (I had hoped to have some significant downtime before my next employment, but...), took a new job with a step learning curve within weeks, which was all consuming, then just as I was about to resurface was offered a promotion (in record time at the company), and the all consuming steep learning curve was back again...

Should have some time freeing up weekend after next (but I do expect the family will want to reserve some/most of it so I'll have to work around their schedule).

Cheers,

Kal

 

Oh no I didn't take it that way. Everyone has been way more than forthcoming with information.

 

I started off with a fresh SD card and an absolutely clean install of Fermentrack using Stretch and php7 and it worked beautifully. I tried adding RaspberryPints and it wouldn't work.

Then, I used a fresh SD card and an absolutely clean install of RandR+ fork of RaspberryPints and it worked beautifully. I tried adding Fermentrack and getting nginx to serve up the Apache2 files and it was a no-go. Nginx took over, but I couldn't access RaspberryPints anymore.

 

@kaljade what are you using for load sensors and how do you have them set up? I noticed that your calculations are included in RandR+ fork. I think I'd rather go that route than flow meters.

Thanks!

 

I'm going to try to get this working this weekend, and will update the docs accordingly assuming I can get it going. Apologies for the silence from my end on this one - this is something that I unfortunately need to spend some time diving into, as it's not an issue I've previously encountered.

 

No pressure, @Thorrak It's been kind of fun trying to get it to work - I've learned a little bit about programming (I just don't have the mind for it; my brother is a whiz!).
I did end up following the steps 4 instructions on GitHub and replaced the 5s with 7.0s and everything went well up until the very end.

Thanks for everything you've done!!!

 

Yea man. This isn't y'all's fault. Y'all are the ones keeping all of these things alive. But I would like to know when they can be running congruently on stretch. It seems you and Rand are the 2 major coders on here wanting to do the heavy lifting. I wish someone like y'all would take the heatermeter code and update it to data log and such.

 

I don't have load sensors set up, I just weigh the full keg before I tap it, and use flow meters after that. RandR+ introduced the load sensor code, my work was only the weight/volume calculations.

These are scales I use FWIW: Accuteck ShipPro 110lbs x 0.1 oz. Digital Shipping Postal Scale, Black (W-8580-110-Black) https://www.amazon.com/dp/B00KYA0RC2/ref=cm_sw_r_cp_apa_i_tOuJCbH1Q2FFS

Ah, gotcha! Thanks!

 

Oh no, RaspberryPints.com is down/suspended

 

That happens from time to time as the originators decide whether to re-up their service...

 

Lately there's been a popup on there asking if you'd be willing to pay for continued development, so either there were enough yeses to justify updating the site or not enough to continue hosting it. Or is that just the eternal cynic in me...?

 

One of the members of the original team was on here a few months back doing an informal survey of interest in a more fleshed-out version that could entail a user fee of some sort. I expect the pop-up was directly related to that.

We've gone through quite a few "outages" over the years that eventually resolved favorably, so I remain optimistic

Cheers!

 

Yep, it's built in:

https://www.realvnc.com/en/raspberrypi/

Those pop-ups may have been the single-most annoying application of dumbassery that I have ever witnessed. No matter what you said they kept coming back.

Given that sort of coding skill, why would one want to pay them for anything related to code?

 

Do we really need the RP site? I've already rewritten the RPints code to run in the latest Debian 9.x, php 7.2.x, MariaDB, et al.
Believe enough have tested.

Only thing we're missing are the download/setup/configuration instructions (for Debian, php, etc) write-up.

Should I post the latest RPints?

 

Rands script FTW! I do think that this thread should choose a code version and stop production on other forks and all put resources into one version. But I can't tell people what to do as I have done nothing but annoy people for help. Haha
