[Version 2 Release] RaspberryPints - Digital Taplist Solution

[RandR+]

In the meantime would it be possible to make a circuit here

First I am by no means a wiring expert, I get a lot of help when it comes to that stuff, but based on your pictures and your first diagram, it looks like its wired where it will work, you just need to create 2 taps in the rpints admin page (enter the pi address into a broswer followed by /admin i.e. http://127.0.01/admin) and assign 1 to pin 8 and the other to pin 9

 

[Gengasi]

Did you see any errors in the first layout? There was no problem flashing the arduino. But still no response after pouring. Would it help with a log?

 

[RandR+]

There was no problem flashing the arduino. But still no response after pouring. Would it help with a log

Flashing the Arduino is a good start.

Yes a log would be helpful.

Also make sure the flowmon service is running from the terminal
sudo /etc/init.d/flowmon restart

 

[Gengasi]

Traceback (most recent call last):
File "/var/www/html/python/PintDispatch.py", line 17, in <module>
import MySQLdb as mdb
ImportError: No module named MySQLdb

This is the log as far as i can tell. The command didnt really have any effect as my pours dont register

 

[RandR+]

import MySQLdb as mdb
ImportError: No module named MySQLdb

Ok that's a new one
Try from the terminal
sudo pip install mysql-python
sudo /etc/init.d/flowmon restart


then check the log again

 

[Gengasi]

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-68YXFx/mysql-python/

after trying python install

 

[RandR+]

after trying python install

I'm gasping at straws here, I haven't seen anyone with issues for python before, what version of Raspbian did you install?

try without sudo
pip install mysql-python
sudo /etc/init.d/flowmon restart

 

[Gengasi]

I installed full raspbian through NOOBS

 

[Gengasi]

same issue when installing without sudo¨.

Thank you for helping me sir

 

[Gengasi]

I got the lines to register that a pour was occuring i did a fresh install of rpints and it worked. However it defaults to zero ml every time

 

[RandR+]

i did a fresh install of rpints and it worked. However it defaults to zero ml every time

That's good news, not exactly sure what happed the first time.

If you look at the log it should say how many pulses it got and what it used to convert the pulses to ml or say that it wasn't configure so look for either
pours.php: No Count Per
or
pour on pin:

 

[LBussy]

Ok, i will add some more photos of how he have wired things up. It looks like a mess to be honest and i dont know if its even possible to see how its drawn. I installed flowmeters and i picked usb. I can see on the breadboard that the resistors are very close to another, maybe even touching?

Yes, that's a bit of a mess. Attached is the wiring instructions for the Swissflow meters. The wire with the black paint is the ground, the opposite is the power, and the middle is for the pulses. While there is a pull-up resistor in the wiring diagram, I believe none is needed. You can hook up the 5VDC to the Arduino 5V power and the GND to the Arduino GND, and the pulses to the appropriate pins directly.

 

[Gengasi]

Hello and thank you for the help again.

Checked nthe log once again after making a pout and this was the output

[RandR+]

conversion: 0

in the admin taps page make sure you set up Count Per Gal/Liter

I assumed you did a full pour and estimate 3710 should be good to start and tweak with each pour then looking at the pours history to see how much RPints recorded. Of course if you did a half pour then you should double to 7420

Will do, come back with more info later

 

[RandR+]

Anything I can do at my end let me know.

So looking at the logs the code runs into a communication issues, it does try to restart communication but that doesnt work (presumably until you reboot)

Sorry if I asked these already but
1. When this happens it sound like the only way to get it running is a reboot, but does restarting the python fix it (i.e. sudo /etc/init.d/flowmon restart)
2. When this happens can you try stopping the flowmon service and uploading the sketch
a. sudo /etc/init.d/flowmon stop
b. open the sketch like you were going to verify it, but instead of verifying hit upload (make sure that under Tools -> Serial Port -> /dev/ttyACM0 is selected)

 

[esdill]

@RandR+ ... Could you please tell me where/how the % full for the temperature gauge is calculated? According to the page source, it's in the .temp-indicator .temp-full style. With my keezer at 38F, it calculates 3.25%, and the red coloration on the indicator is so small it doesn't even show up. I'd like to see if I can increase that percentage somewhat, otherwise there's no sense even showing the indicator.

 

[RandR+]

full for the temperature gauge is calculated

it just takes the last temp and uses that as the percent
in file index.php ~line 236
<div class="temp-full" style="height:<?php echo $temp; ?>%; padding-right: 50px"></div>

I tested with 38 and it showed correctly on my test system

This is what 37.1 F looks like on mine ... for what it's worth ... 2.95 C = 37.3 F, and index.php shows 2.95% ... so it looks like the indicator is using "C" instead of "F".

it just takes the last temp and uses that as the percent
in file index.php ~line 236
<div class="temp-full" style="height:<?php echo $temp; ?>%; padding-right: 50px"></div>

I tested with 38 and it showed correctly on my test system

Until you can determine why the indicator is using the Celsius value for the indicator level, I fixed my version by ...

<div class="temp-full" style="height:<?php echo ($temp*9/5)+32; ?>%; padding-right: 50px"></div>

 

[Gengasi]

Thank you everyone for great help regarding my issues in setting up the flowmeters and rpints. I have now a rpints with flowmeters running, despite having no technical knowledge

 

[RandR+]

Celsius value for the indicator level,

The temp probes log in Celsius, but the temp is changed to Fahrenheit for display. I don't have temp probes so I just made up the data and by default used Fahrenheit.

If I put in the test data as Celsius then I get the same thing, so thanks for pointing this out.

I put in a change to convert the temp to Fahrenheit like you did but to use the function that is used to change the temp for display:
So it become this:
<div class="temp-full" style="height:<?php echo convert_temperature($temp, $tempUnit, UnitsOfMeasure::TemperatureFahrenheight); ?>%; padding-right: 50px"></div>

 

[RandR+]

ACM1 is selected and I don't know how to change it?

If the editor cant see the ttyACM0 then I doubt the python can, BUT that doesn't explain why its jumping ports like it is.
A really janky fix is to catch when it cant open ACM0 and try ACM1

Something like replacing Lines 223 through 226 of python/FlowMonitor.py with

        if flowMetersEnabld :
            if self.alaIsAlive is False:
                debug( "resetting Arduino" )
                self.dispatch.resetAlaMode()
                try:
                    self.arduino = serial.Serial(self.port,9600,timeout=.5)
                except:
                    if self.port == "/dev/ttyACM0":
                        self.arduino = serial.Serial("/dev/ttyACM1",9600,timeout=.5)

But still doesn't work. So then I hit the reset button on the Arduino. And the log added this and finally it registered a pour

Is the first time you had to hit the reset button?

I'm trying to see if there is a way to reset the Uno programmatically from the pytho, there is for the alamode board, but it might not work for UNO
Nothing pops up right now but I will keep looking, I might have to be a sketch change that if it doesn't get a response back in xx seconds then reset itself, but if the sketch isn't running until the reset button is pressed then even that wont fix this

Perfect ... thanks! I will adjust mine to be the same.

One more suggestion (not earth shattering but worth consideration) ... on the admin/temperature probe page for the lowest possible and maximum temp values, there's two typos:

Highest Temerature:
The highest temperature possibles

In addition, these values appear to be Celsius, so adding (C°) to each would be a good reminder to people entering values here.

This the the first time Ive actually just hit reset on the Arduino as before that I used to reboot the pi and power down the Arduino.I never thought to just reset the Arduino until last night so tried it and it worked.

Today its stopped again and this is the log file since last nights pour.

I tried resetting the Arduino with the reset button again but it didn't work. So I stopped the flowmon, tried to upload the Arduino and it now says Serial port /dev/ACM1 not found, did you select the right one from the tools.Serial port menu. However the serial port menu is greyed out.

I then typed dmesg in terminal and get this

EDIT- So after numerous reboots of the Arduino nothing happened and serial was still grey. So I unplugged the usb cable to the Arduino and plugged it back in and rebooted the pi and now ACM0 is showing again. (Does plugging the usb cable into different ports change this as I did try doing that?)

Stopped flowmon uploaded the sketch, and started flowmon again..but no pours. Then I reset the Arduino and it works. So it seems as if after I re upload the sketch I have to reset the Arduino before it works again. Heres the log from the upload then restart of the Arduino. (But it won't be working tomorrow no doubt)

[RandR+]

Does plugging the usb cable into different ports change this as I did try doing that?

different physical USB ports will have different logical port names, so yes switiching USB ports makes sense the port would change

So it seems as if after I re upload the sketch I have to reset the Arduino before it works again

It seems that way but I'm not sure why, because I would think that uploading would reset the Arduino, ill look into this.

 

[troyp42]

So thats why it changes from ACM1 to ACM0 and back?

 

[RandR+]

most likely

 

[troyp42]

most likely

Ok Ill keep it on the same usb port then which is now currently ACM0. It has stopped working yet again so appreciate you looking into this for me.

 

[RandR+]

there's two typos:

Fixed, thanks!

Does the log end with "waiting for Arduino to come alive"?
Does hitting the reset button (without doing anything else) get it to work?
From your previous logs the python was trying to handle the exception correctly, but the Arduino wasn't coming back up like it was supposed to. Either the Arduino didn't establish connection to the pi again or it didn't start the sketch after uploading.

Do you have a dedicate external power source for the Arduino? it seems like a lot of issues with them are caused by power issues.

 

[troyp42]

Yes I think so, Ive seen that in most instances
Does hitting the reset button (without doing anything else) get it to work?
From what I can tell I have to re upload the sketch first then hit reset, but that could be due to moving the USb cable first. Will have to test this more and come back to you.

Yes I have a 9V 400ma power supply direct to the UNO.

 

[day_trippr]

fwiw, while 9V is ideal, 400ma is marginal. Not claiming that's the root cause issue here, but I use 9v 1a wall warts ($3 delivered via eBay - eventually ) for my Arduinos (Unos, Megas - even my one Nano) and have had zero issues over many years. If one wants to take power issues off the board (and hopefully resolve flakiness in the offing) that's one way to go...

Cheers!

I do have a 12v 4a power pack. Would that be too much?

I just got home and Here is what I did in order.

1. Poured beer, - no pours registered.
2. Reset Arduino, - no pour registered.
3. Rebooted Pi, - no pour registered.
4. Stopped flowmon, went to uploaded sketch but serial port was greyed out so unplugged usb and plugged back in.
Uploaded sketch, restarted flowmon, -no pours registered.
5. Reset Arduino again, - no pours

This is the log file since the reboot of the pi and trying to upload the sketch.

EDIT- I unplugged the usb cable to "Un-grey" the serial port connection, and I plugged it back into the same USB port on the PI. However it has now switched to ACM1 even though I didn't change ports. So I unplugged it and tried different ports resetting the Arduino until it showed ACM0 again (It even showed ACM2 on two usb ports) then uploaded the sketch.

Now the log says this

EDIT2- Switched to a 12v 4A pwr supply. Rebooted the pi and reset the arduion and pours started working again. Lets see what happens tomorrow night...

 

[JAKL]

If using my version, Check /var/log/rpints.log or in the admin section under install there is a log page.
That might give you a hint as to why its not working

I checked /var/log/rpints.log and it shows:

blah blah... pintdispatch.py”, line 17, in <module>
import error: no module named MySQLdb

when I did the install it did ask for an admin user pw but it wouldn’t allow me to type one in so I left it blank (that was the only issue during installing it all)?

 

[JAKL]

Traceback (most recent call last):
File "/var/www/html/python/PintDispatch.py", line 17, in <module>
import MySQLdb as mdb
ImportError: No module named MySQLdb

This is the log as far as i can tell. The command didnt really have any effect as my pours dont register

I have the exact same error, did you happen to find a solution to this one?

 

[JAKL]

I'm gasping at straws here, I haven't seen anyone with issues for python before, what version of Raspbian did you install?

try without sudo
pip install mysql-python
sudo /etc/init.d/flowmon restart

I’m getting the same errors that Gengasi was having, ie try to reinstall python and get error:

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-68YXFx/mysql-python/

do you know what he did to resolve his issue? was it a fresh rpints install?

 

[RandR+]

user pw but it wouldn’t allow me to type one in so I left it blank (that was the only issue during installing it all)?

The password isn't printed when you type it nor are asterisks indicating you typed something so you probably did enter in a password but couldn't tell

do you know what he did to resolve his issue? was it a fresh rpints install?

Yes reinstalling rpints again reportedly fixed the issue
