Click to expand...
Kinda, I have the logic to rearrange columns in the list view, but I don't have an easy screen to do it yet.

If you are familiar with MySQL you can go into the database and change the configValue column of the results
select * from config where configName like '%ColNum'

Or wait until I get the screen finished.

while I have specifically seen that error it seems your serial connection stopped working, were you playing around on the Pi or bumped it when this happened?

Did you try restarting the flowmon service to get it back to working?
sudo /etc/init.d/flowmon restart
 
Hey guys - just a quick poll / affirmation needed. Are you (like @RandR+ @Tobor_8thMan) getting utility from the DNS records hosted at rpints.com?

It's time to renew and I just want to make sure you are using it.

For the rest - are you using those links to install?

I got the initial version of my customize screen committed:
On the Admin page, under the Personalize menu there is a new entry "Customize Tap Display" the only thing is it only display the list in vertical mode because I cant get drag/drop working on the horizontal, but eventually you will be able to decide on which way to display and eventually control a lot more (like font size)

But for now it will allow you to drag to reorder how columns/rows and also there are radio buttons to show/hide the column.

I didn't bump the Pi, its up on top of my fridge. I tried restarting the pi and flowmon using the links in the admin page and it didn't work. I had to reboot the pi and the Arduino. But why does it do this every now and again?

Its tough to tell, I haven't seen that in my setup, one thing you can do to help troubleshoot and trace more out is in /python/Config.py
change

line 16 - config['dispatch.debug' ] = False#True

Is there any way to report the temperature that one the plaato keg reports?


https://plaato.zendesk.com/hc/en-us/articles/360003235097-GET-value
e.g. v69

Not right now, I could see adding in a configuration that allows you to say use Plaato Temp and If a Plaato keg was defined it would query that for tempurator

I just committed the change, there is a new configuration Use Plaato Temp that will show the plaato value as is (i.e. will not convert the temp to the display temp)

When I modified Raspberry Pints I basically left the original logic "as is". I did modify things for newer mariaDB, php calls, OS, rendering and remove dead code. I also modified the glass graphics as, IMO, they looked better.

I checked all the Raspberry Pints code (.php, et al) and don't see any references to "rprints.com".

I have a French door type fridge/freezer as my kegerator, so i have two different temps. Typically i keep carbonated water, soda, mixed drinks on the freezer side where it’s cooler (~33 deg F) and beer on the fridge side Where it’s not as cool (38-40 deg F).

I see by default the temp is taken from the first plaato authentication token. Could i easily modify which token it uses or make it so it reports two temps (e.g. reports temps from 2 diff auth Tokens)?

The first commit was just a quick and easy change for me, with a little more time, I now committed it to make plaato temps look like temp probes (including temp conversion) so if you have multiple plaato kegs configured each one will show up on the screen

Sweet!! Thanks again
 
Load sensors. Might work well if they have a good drift management algorithm - and perhaps a reference sensor.

I was spitballing something reeeeally simple, basically a tiny digital scale with maybe 8 buttons hooked up to an Arduino to create the same pour messages that RaspberryPints expects. Fill the glass, set it on the scale, press the tap button, et voila...

Cheers!

Ok here is the latest log file after a complete reboot. I had this error last time and ended up buying a new Arduino. This time Im powering it separately just to be sure..

EDIT:_ When trying to re upload the .INO file to the sketch I get the following error message..

Serial port/dev/ttyACM not found

Retry the upload with another serial port. And it lists /dev/ttyACM1. So I chose that one and the upload completed. But still no luck..

i used the site recently when I updated my RPints.
 
Ok guys I probably shouldn’t be messing with this much technology but I’ve gotten this far and I’d really like to see this through to fruition

I am completely lost when it comes to
wiring and programming. Is there a clear walkthrough for wiring up and adding the flow sensors and the code? I tried the RaspberryPints.com tutorial but it looks as though this version had changed and the instructions don’t seem to match.
I have 3 flow meters

I also don’t ever post in forums so if I did it wrong please fix me.

That one is easy enough, look for this in your index.php file:
PHP: 
                <div class="HeaderCenter">
                    <h1 id="HeaderTitle">
                        <?php
                            if (mb_strlen($config[ConfigNames::HeaderText], 'UTF-8') > ($config[ConfigNames::HeaderTextTruncLen])) {
                                $headerTextTrunced = substr($config[ConfigNames::HeaderText],0,$config[ConfigNames::HeaderTextTruncLen]) . "...";
                                echo $headerTextTrunced ; }
                            else
                                echo $config[ConfigNames::HeaderText];
                        ?>
                    </h1>
                </div>
Switch it for something like this:
PHP: 
                <div class="HeaderCenter">
                    <?php if($config[ConfigNames::UseHighResolution]) { ?>           
                        <img src="img/logo/centre.png" height="200" alt="">
                    <?php } else { ?>
                        <img src="img/logo/centre.png" height="100" alt="">
                    <?php } ?>
                </div>
Image location and title changed to suit your environment of course.

It has been a few years since I have messed with raspberrypints but I want to see if I can get this logo thing figured out. I had gotten this response from Kal back then on how to do it but I'm a little lost. I figured out how to access the index.php file. Now I'm trying to replace the current text with what Kal recommended. He said to change the image location and title but I'm not sure what to do there. I'm guessing I need to get my image onto the pi somehow? Anyone have some advice here?

What version of Rpints are you using?

The original instructions are good for wiring, but not much else at this point. My version of Rpints doesn't need any code changes to get the flow meters working, just go to the admin taps page, if flow meters are enabled you will see textboxes where you can input the information about the flow meter. You can also check /var/log/rpints.log for more errors

looks like you are trying to put the logo in the center of the screen. make the changes Kal recommended then change img/logo/centre.png to the location of the image on the Pi based from the Rpints install directory (usually /var/www or /var/www/html)

This is the part that is confusing to me. Sorry this stuff is way over my head. I have the image on my laptop. I use the laptop to access the Pi through Putty. But I don't know how to get the image to the pi.

you can use an FTP client for easy file transfer, FileZilla or winscp are two that come to mind. download one and then access the pi the same way you do with putty

I'm using the latest version that I downloaded from rpints. (RandR version) and I'm just kinda lost.
I'll look in the admin section to see whats up there. Its probably right in front of my face. I still cant seem to figure out how to wire more than one meter to the board. Is there a picture of an easy, multiple meter set up kinda like this on from winovino ?

I don't have an easy wiring solution like the picture (it looks like they got a bread board to connect all the power wires together with short jumpers)

What I did is soldered all the black wires to a single wire and all the red wires to a single wire then the single wires were plugged into the board (like you have your single red and black)
Then ran all the yellow wires to different pins on the board (had to solder extensions onto them)

Ok this is starting to come back to me. Turns out I already had Winscp on my laptop. So I got the image transferred. Location I believe is /var/www/html/img. So when I change the index file should it look like this. And I can do these changes right from Winscp correct, I don't have to go back to Putty?
<div class="HeaderCenter">

Ok, that sounds like a pretty easy solution and I think I can do it. I'll give it a try and see what happens.

I don't have an easy wiring solution like the picture (it looks like they got a bread board to connect all the power wires together with short jumpers)

What I did is soldered all the black wires to a single wire and all the red wires to a single wire then the single wires were plugged into the board (like you have your single red and black)
Then ran all the yellow wires to different pins on the board (had to solder extensions onto them)

I soldered all the black wires together and then soldered all the red wires then connected the yellow wires to pins 8,9,and 10. I changed the PIN numbers under taps on the admin page and still no jive. I also tried running FlowMonitor.py and nothing happened
i got to thinking that I might have messed up during the install. I selected usb and I bet I should have selected serial because I don’t have anything connected by usb.... except my wireless keyboard/mouse. Do you think this is right?

Does anyone know how I can get this logo in the center of the header area?

I got this figured out as well.

Has there been any updates or changes to this program in the last 3 years or so? This thread has doubled since the last time I was caught up.
