You have to enable the "Keg Column" and turn on "Use Flow Monitoring".

Not sure why you weren't getting any pour packets displayed in the terminal window, unless the flowmon service was still running the whole time.
Which OS are you running?

Cheers!

Ah! It was the keg column selection that was NOT done. Now it is showing, and responding to the flow monitor when I blow through it by updating a loss of volume and a corresponding new balance.

Curiously, the updating of the RP page while running "sudo python /var/ etc." was because the flowmon was still running. When I convincingly stopped it, the RP display did not update.

Then, when I ran the script "sudo python /var/www/python/flow_monitor.py" or "sudo python /var/www/html/python/flow_monitor.py" and blew through the flow meter, again there were no pour packets displayed in the terminal window.

After exiting, I did see these things, respectively:

pi@raspberrypi:~ $ sudo python /var/www/html/python/flow_monitor.py
Exiting
Traceback (most recent call last):
File "/var/www/html/python/flow_monitor.py", line 36, in <module>
POUR_COUNT = str(reading[3])

Never seen this before.

File "/var/www/html/python/flow_monitor.py", line 35, in <module>
MCP_PIN = str(reading[2])
IndexError: list index out of range

I wonder if it means your Arduino sketch is sending an invalid pin number with the pour packet.
Might want to double check the number of taps and the pin list in that sketch...

Cheers!

Lines 35 and 36 in that file reads as shown in the following context:

try:
while running:
msg = arduino.readline()
if not msg:
continue
reading = msg.split(";")
if ( len(reading) < 2 ):
print "Unknown message: "+msg
continue
if ( reading[0] == "P" ):
MCP_ADDR = int(reading[1])
MCP_PIN = str(reading[2])
POUR_COUNT = str(reading[3])
PULSES_PERL = 5600

Here is what I have in the Arduino sketch:

//This line is the number of flow sensors connected.
const uint8_t numSensors = 1;
//This line initializes an array with the pins connected to the flow sensors
uint8_t pulsePin[] = {8};
//number of milliseconds to wait after pour before sending message
unsigned int pourMsgDelay = 300;

Has anyone tried to "update" and install the "Version 2 additions" located in the pull request? I ask because there was a couple more features I liked and so I gave it a go and tried to install but its not recognizing my pours.

Attfuzz · Mar 14, 2017

Instead of soldering, you could get a wire wrap tool like phone company technicians use.

So, scratch it not working, i got it working. But the big reason why I wanted to install this so it would update a remote display. In the bug fixes it says "RPints now updates keg pours (and other stuff) to remote browser displays"

I take that as a tablet or whatever browser you have open to the page will automatically update after a pour. Its still not doing that, I have to click refresh on the browser from my remote display. (I get that i can download a chrome extension to update however I want but just curious) Any ideas?

So... Website is down. Anyone have access to the archive?

I started trying to get it packaged for distribution, but it turned into more hassle than I expected. I actually ended up writing my own very stripped down version that has just the features I need. For example, I really don't need keg inventory and found it quite cumbersome to have to manage the keg tracking subsystem and enter OG/FG/SRM/IBU, etc. twice just to get things displayed. This is not a criticism, just my own preference.

A couple people expressed interest in the container/glassware rendering code, so I published my new project at github, which contains that, at https://github.com/y0gensha/LitePints

I also zipped my RaspberryPints folder with all my modifications before I nuked it. You can get it at http://yogensha.net/junk/pints_yogensha_bak.tar.gz Use at your own risk!

It's in the img/ folder of both projects and is actually very simple.

If any of the original developers are around, thanks for contributing the project. Also many thanks to day_trippr for the motion sensor stuff. Certainly added joy to my own home brewing!

Awesome. May fork off this. Do you have a list of packages I would need to install? Was going to do a RaspPints install but the site is down.

day_trippr · Mar 16, 2017

Give the guys a couple of days to get their payment into the hosting site.
If they're still off the air on Monday there are a few of us who dumped the site...

Cheers!

Attfuzz · Mar 16, 2017

So, I'm at step 6 on a clean install and on the last command I get "sudo: unable to execute ./setup: no such file or directory". Thoughts? Once past this, I'll move on to step 7 on post #1387 (think that's the one). Unless there's a better walkthrough somewhere with all of the Capn's updates. Thank you.

Here is something I put together the other day when the site went down. I used Google cache to get some of the code back. I used this and it worked great.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get -y install apache2 php5 mysql-client mysql-server php5-mysql phpmyadmin
sudo apt-get install arduino python-serial python-mysqldb php5-cli xdotool
sudo apt-get -y install ttf-mscorefonts-installer x11-xserver-utils unclutter

Download zip and move to var/www/html
Here is link to download zipfile https://github.com/HentschelT/RaspberryPints/tree/Version2

sudo chmod -R 777 /var/www/html
cd ~
git clone https://github.com/google/pywebsocket.git
cd pywebsocket
python setup.py build
sudo python setup.py install
sudo cp flowmon /etc/init.d
sudo chmod a+x /etc/init.d/flowmon
sudo /etc/init.d/flowmon start $ ps aux | grep PintDispatch.py
sudo update-rc.d flowmon defaults

Attfuzz · Mar 16, 2017

Tried what you posted and at "sudo cp flowmon /etc/init.d" get "cp: cannot stat `flowmon`: No such file or directory. Thanks.<EDIT> Nevermind, think I see what you mean, just jumped around some. I just can't seem to get past step 6 on the last command, the setup won't execute.

day_trippr · Mar 16, 2017

If you log into the RPi as 'pi' and do an 'ls alamode-setup' does the response show that folder and a 'setup' file within?

btw, what OS version are you running - Wheezy (older) or Jessie (newer)?
If running Wheezy you'd run the 'setup' file, if Jessie there should be a jessie-setup instead.

And if you're running Jessie, when I installed R'Pints under Jessie I had to install DOS2UNIX on the RPi and run it on the jessie-setup file to get it to run correctly.
That was many months ago so the jessie-setup file might have been fixed but it doesn't hurt to run DOS2UNIX on it anyway...

Cheers!

Did you restart ?

Attfuzz · Mar 16, 2017

Yes the file is there. Running Wheezy. Yes rebooted.

day_trippr · Mar 16, 2017

It's hard core, but I've done it: run each command in the setup file from the console.
That'll at least get you down to which command in the script is failing...

Cheers!

Attfuzz · Mar 16, 2017

Did that. Nothing failed. The setup file doesn't show anything happening with the inittab folder or the arduino-setup folder though, should they be somewhere?

Did you open and edit the flowmon file to var/www/html before you pasted it in the init.d location?

Negative, that looks like something around step 9, I'm still stuck on step 6 with the setup file not wanting execute. Ran all the commands in the setup file, but it doesn't do anything with two of the files. I'm also having troubles downloading the zip file Version2.zip for the next step, may have to get a jump drive involved.
<EDIT> So, I continued on with the install, last command in step 6 did not work again on a clean install, but went through the setup folder and did all of the commands. Now, on step 9 that tests and starts the flowmon, I get nothing on the return using PintDispatch or flow_monitor. I've only got one meter using pin 2. Changed the arduino code to "int numSensors = 1;" and "int pulsePin[] = {2};". Running Wheezy with Version2 of RPi, so it's all in /var/www/. Thanks for the help.

So its working? Thats odd if your using the updated version 2 add on that you have to specify the pin. The whole point of that version is you dont have to, all you have to do is specify the pin in the actual raspberrypints site location.

Not working. Oh, I see. Do I still need the number of sensors? I left it at 1 sensor, deleted pin 2 and set it back to maxpins. Still nothing on the output when testing and starting flowmon. I also started a clean install with Jessie, still had problems at the last command on step 6, the setup file (jessie) would not execute, so did them all separately from the setup folder. Continued on with the install. Now problem is when trying to upload to the alamode board, the serial port section is grayed out and I can't select the serial port??? Thanks again for the help.
<EDIT> Looks like all is working and good on Wheezy, just not registering pours on Jessie. At least one of them works :>)

day_trippr · Mar 17, 2017

I had a number of issues getting things running under Jessie (on an RPi2B) not the least of which was getting the serial port to work with an AlaMode shield.

This was the "eureka" fix:

Edit /boot/config.txt
Change enable_uart=0

Cheers!

I'm running on Jessie , rpi3 with Arduino Uno. Registering pours.

moad · Apr 6, 2017

Hi all,

I'm using an Arduino Uno and RPi2. RPints is up and running and i have the sketch with one pin specified as a test on the arduino. I can see the info in the serial monitor of the arduino and the pin matches what I have set on the Rpi however there is no data hitting the pours table. I've checked the paths in config files and it all looks fine. I'm a bit of a linux novice so if someone could point me to a log I should be checking I'd appreciate it muchly.

Cheers,

Nick.

edit: nevermind I went back through the flowmon file and found the missing html in the path, what a pain.

Now to look at converting to metric!

day_trippr · Apr 6, 2017

Well done for getting up and running! :mug:

About the only gotcha with converting to metric units will be coming up with a "ticks per liter" factor for the flow meter. The rest should be straight forward...

Cheers!

We usually get a much longer show when a new adopter comes along. We didn't even have time to figure out who's turn it is to bring the popcorn!

Lost_Arkitekt · Apr 10, 2017

I unplugged my RaspberryPi and Pints a few months ago because I moved, now it gets to some USB and/or Keyboard Error (cmd13) and won't load anything...not even the Raspbian desktop. Any suggestions.

day_trippr · Apr 10, 2017

If you unplugged a running RPi without executing a Shutdown command beforehand you likely borked the SD card.
If you have a backup, now is the time to use it.
If not, you're looking at a whole new build...

Yeah...my SD card says it has 1.34gb total (was a 16gb card) and now I can't format it. Any suggestions, or should I just buy a new one? Also, do you think the wifi dongle is fine?

One last thing. I read on Facebook last year where you guys might be coming out with RPints V3. Any news on that?

Thanks.

Sounds like you're looking at it in Windows. If that's the case, you won't see the full size because of the Linux disk format.

However, you can wipe it in Windows and start fresh.

Here's the steps:
Start diskpart (from command prompt)
List disk
Select disk x (sd card #)
Clean
Create partition primary
Format fs=FAT32 quick
assign (to get drive letter in Windows Explorer).

Sometimes you need to eject after the "Clean" step and re-insert so Windows see's the full capacity.
