Ok did that (After having to run sudo apt-get update first as it wouldn't work) Now chromium doest start in kiosk mode automatically anymore. And my browser shortcut on the task bar opens a browser called Dillo???

How do I get chromium to open in kiosk mode again?

ooops missed -browser
try this
sudo apt-get uninstall chromium
sudo apt-get reinstall chromium-browser

For kiosk mode the easiest thing to do is to rerun the installer, but select reconfigure pi, after you select a monitor it will prompt for kiosk mode

Im getting this

pi@rpints:~ $ sudo apt-get uninstall chromium
E: Invalid operation uninstall
pi@rpints:~ $

EDIT- Worked it out,.. Thanks again, its working again in kiosk mode.

EDIT- No it doesn't work.... every so often it refreshes and goes to a black screen that says waiting for cache and I have to shut down chromium and open it again?

@Dellboy78 here's one data point with success with the DBS026 flow meters:



The poster also says that they tried cheaper flow meters and had foaming issues.

Ah, great, thanks! Only just seen this for some reason! I’m quite tempted to try these. I did email them to see if they could give me any more info, but I’ve not had a reply yet!
 
Hello guys, seems like I have ran into more problem 😅 Somehow I broke my raspberry pi 3b when I tried to install it in a new case, therefore I bought the raspberry pi 4 from my local shop. I tried installing the Randr branch on this one but after rebooting after installation the screen is just black (backlight turns on). Is there somehow an issue with Rpints on raspberry pi 4?
 
LBussy said:
What "screen?" Do you have one of those case-mounted displays? You need to add the drivers for that if so.
Click to expand...
Yes I have the case-mounted display. I had Rpints up and running on the 3b+ before I broke it. I modified the case to fit with the pi 4. The screen did work on the raspberry pi 4, even after rebooting. Then i installed Rpints and after reboot the screen is black. Tried 4-5 times with same result.
 
So I'm trying to get flow monitors working and when I look at the rpints log i see this:

I've tried reloading the sketch to the audrino, but no luck. Any idea what's going on with it?

Not sure what your level of expertise is but mines a beginner but Ive been playing around with mine for months and months and heres some stuff that Ive been told that worked in the past..

To get file permissions to change files do this (Aplogies if you know this)

sudo chmod +777 /var/www/html -R



Try this if you havent already..

In /var/www/html/python/FlowMonitor.py change line 225

from

self.arduino = serial.Serial(self.port,9600,timeout=.5)

to

self.arduino = serial.Serial(self.port,115200,timeout=.5)

and save


in the raspberrypints.ino change line 124

from

Serial.begin(9600);

to

Serial.begin(115200);

Then repeat the upload process

Also check this.

go into config.py and uncomment this line..
config['flowmon.port' ] = '/dev/ttyACM0'. (Assuming your using ACM0)

That has both worked for me with a similar error to yours.

I have to get better terminology in those messages because that actually is normal. NOTOK is for the RFID reader portion not that there is an issue and I don't have it log out the message over and over because it would fill up the log so you are actually good to go from the sketch and python perspective.

If you try to pour a pint what does the log say? You may need to turn on python debugging to get more information by going to Config.py and changing False#True to just True for the following lines

#logging settings for flowmon
config['flowmon.debug' ] = False#True
#logging settings for pintdispatch
config['dispatch.debug' ] = False#True

"no display" when installing RPints. I'm not sure how to fix it now - maybe resintall the screen's drivers?
Click to expand...
if you seleted a screen during install you may need to revert the changes for the monitor by either ssh into the pi or attaching an hdmi monitor/screen to it

in /boot/config.txt
look for hdmi_group and hdmi_mode, the script first comments out lines starting with those and then adds in them back in with the option you choose for the monitor resolution
the same thing is done for display_rotate.
If you have no commented out lines (starts with #) for those and those lines exists try removing them/commenting them out
If you both commented out and uncommented lines try to switch the commented lines (remove starting # and add # to the other)

then finally is the screen blanking settings which are in either
/home/pi/.config/lxsession/LXDE-pi/autostart
or
/etc/xdg/lxsession/LXDE-pi/autostart

comment out or remove
@xset s off
@xset -dpms
@xset s noblank

that will reset the monitor settings, the last setting is starting chromium in kiosk mode which will be in the same file as the screen blanking settings as a line like
@chromium-browser --kiosk localhost
 
So I turned on debugging for the python script. Here's what I got in my log:

2020-07-30 15:26:24 RPINTS: unknown message: SatusCheck;

I tested out the flow meter on the arduino using a different sketch to monitor flow, and it worked so the flow meter and arduino hardware seem to be ok.

Hopefully the log can help with troubleshooting.

This looks like messages are coming from the Arduino but are getting messed up. Ive seen this if the serial monitor is open.

troyp42 had a bad usb cable that was causing this.


Is there anything else running on the PI that could be trying to access the Arduino.
 
Feature request:

Custom column for accolades. When entering a beer, you could select the number of Gold, silver, bronze, BOS, medals it has won and display that on the screen. How hard would this be?
 
apscherz said:
That would be incredible. Thank you!
Click to expand...
No problem, accolades are in now. Big thanks to @garzlok for the images, I left them on the small side until someone says they should be bigger. Eventual the size will be more configurable

If you rerun my install script it will detect an installation and ask if you want to update. Hit yes and you can add accolades to the beer. You will have to enable the accolade column on the home screen as that is disabled by default (under Configuration hit on for "Show Accolades Col:")

Yes, that is a compare of the your local files to the latest GitHub files so that if you made changes you can see them and recreate them. The newer installer will install kompare which is the graphical version of that.
I think you can just hit cntrl+c to close the compare and continue the update

I just took a backup of the DB and reinstalled. Works like a champ! Only thing I'd throw out is they don't appear in order of importance (bronze on bottom, BOS on top, etc), but rather by order in which you enter them. I would be nice if they would sort by importance, or give you the ability to move them. Also, a small text description on the display might not be terrible.

Last thing, how hard would it be to make additional fields there? For instance, there's a competition in Texas called Bluebonnet that awards Steins for gold medals, which are highly sought after, it would be cool to put that on there with an avatar of a stein, or similar for other huge competitions.

You guys are making this amazing, and I love RPints, not sure where you are located but I'd be happy to send you some thank you beers if you're interested.

Cheers!

I could a ranking to the accolades and sort by that then you can give an accolade the rank you want it.

Probably should have added to the original post about adding them that I treated them like ingredients in that you can add your own and change images/text by going to the admin page on the left under Ingredients there is a link for Accolades. Click that and you can customize them.

If you upload an image the image is used but if you remove the image the name of the accolade is used on the main display (just like tap numbers). I have type and notes for the accolades but they really don't do anything.

Thank you for all the help with this, it's really awesome and I'm excited to start uploading the data. For whatever reason though, I can't seem to create a new accolade, it says successful but refreshes with only the 4 existing medals shown. Any ideas?

I had logic that if the name is empty it wont add it, I now set the name to new if the name is empty on save. Also fixed it so the image isn't copied when adding a row.

Also added the rank field to accolades for sorting

You will need to update to get the rank and add new fix.

well... that bricked my raspberry pi :/ got an error:
error 1136 (21501) at line 799: column count doesn't match value count at row 1

when installing the DB. tries to finish the install but just loads a white screen with nothing on it
 
RandR+ said:
forgot to update the create sql to include the rank, fixed now if you reinstall

That seemed to do it. Thanks for the quick response. Only thing I see now is that it doesn't launch in Kiosk mode anymore, but maybe I missed something
 
RandR+ said:
On install did you select a monitor and select it to open in kiosk mode?
Click to expand...
...no. I cancelled out of that screen hoping to be clever and avoid having to redo my settings to get the screen to fit. When I do it the right way it works lol.

The problem I'm now seeing is this:

If I try to run the "upgrade" option, I get the split screen "illegal file name" error I posted above, hit ctl-C and it cancels the upgrade.
If I backup the DB and do a fresh RPints install, then restore the DB, there's no "Show Accolades Col:" in the configuration tab.

Install kompare , from the terminal enter
sudo apt-get install kompare

This will bring up a new window instead of doing everything in the terminal. I'm having trouble getting compare to exit when running it from the script.

Ok that worked, and I can upload custom images for the accolades. However, when I try to add it to the beer and click "save" the screen turns white and doesn't apply it to the beer entry

Its working on my test system with latest. Is there any text in the upper left corner? If you give it a minute does it refresh to the beer List page?

can you look at the end of /var/log/apache2/error.log and post that here?

I don't see anything on the page at all. the last couple lines (after I tried doing it again):

Nevermind, I got it. The untappd stuff clicked for me. Removed the name and it worked. I'm going to go through and update everything. Thank you, Thank you Thank you! Sorry, I know I've probably been quite annoying with this but I really appreciate it.
