[Version 2 Release] RaspberryPints - Digital Taplist Solution

[Gengasi]

Did you manually enter in 6770 as the count per liter on that one?

On tap nr 1 i manually configured 4429. The flowmeters have drastically diffrent reading results. I poured 100mls and it registered as 100mls in the "pourlist". I dont know if the remaining value on the keg adjusted accordingly, as i have not keg connected on tap 1.

My guess is the keg would have reduces correctly, the issue isn't the math, its the unit associated with each tap, the calibration page before set it to gallons, but didn't convert the count per liter to count per gallon causing the pour to be registered as oz instead of ml which then displayed the wrong value.

By using the tap page to manually set the count to 4429 it correctly set the unit of the tap to ml so each pour is registered as ml

Ok, thank you. Do you see any traces of this in the code?

I saw it before the fix.

You can check /var/log/rpints.log to what the values where when a pour was registered it would start with pour on pin

My temperature probes had been working consistently, without fail, for months. I ran the update so I could get the latest version (RandR+) with the new pour calibration function, and now my temperature probes are no longer working. My pours are being captured, so the flowmonitor is running.

Here's the log, note the "Unable to run 1Wire Temperature" entry:

2020-09-27 18:00:13	FlowMonitor	I	Unable to Run 1Wire Temperature	1

Any ideas?

 

[RandR+]

"Unable to run 1Wire Temperature" entry:

in python/Config.py change
config['flowmon.debug' ] = False#True
to
config['flowmon.debug' ] = True

and restart the service (sudo /etc/init.d/flowmon restart)

this should trace out the error that is causing it to stop running, you can post the log here afterwards

1Wire Temperature: '28-030297940199'

this indicates the temp thread started, but I don't see anything after that to indicate there was an error with reading temperatures.

Is there more log generated after you posted that? Is the temperature reading correctly now?

 

[esdill]

That's the end of the log, and the temperatures are still not updating:

Probe	Temperature	Date

They stopped at 14:16 yesterday, the same time my software update was performed.

 

[RandR+]

That's the end of the log, and the temperatures are still not updating:

ok I found the issue after testing on my side. I added some logging to help track down when temps were not updating and apparently never tested the trace so that was throwing the exception.

If you update RPints you will get the fix

 

[esdill]

Yes sir ... it's working now. Thanks!

 

[Gengasi]

I also had the temperature probe issue, but it is working now, thanks!

Hi Guys,

I am trying to setup Rpints on a Pi3. I am not terrible with coputer stuff but I have hit a wall. I get to the installer page of Rpints and enter the root pw, database pw, and admin username/pw then hit setup. When the next screen loads I get the below message and have no idea how to fix it, any ideas?

Validating Entries...Success!
Checking DB connectivity...
Warning: mysqli_connect(): (HY000/2002): Connection timed out in /var/www/html/install/includes/configprocessor.php on line 52

The original Rpints doesn't work on Raspbian past Jessie/Wheezing because the MySQL calls it uses are depreciated most likely this error is because you cannot sign in as root on the latest msyql

an easier install process to get a version that works on the latest is to run this from the terminal on the pi
curl -L install.rpints.com | sudo bash

it will give you a choice to install mine (RandR+), Tobor, or original, Mine has a lot more features then the original and supports the latest OS, Tobor's is the original updated with the correct MySQL calls

Awesome! Thank you! Does this override the previous files or do I have to delete them?

Hi, apologies if this has already been covered in this thread. I have my three tap system working beautifully with flow meters but I'm considering adding a fourth tap to my keezer. Is this process straightforward or does it require a complete re-install?

No reinstall needed I think. Just change the amount of taps to four in the "taps" section and assign the correct pin to the forth tap.

I just found the setting, thanks!

I really like the new glassware a saw there are new "corny" images. How do I change the keg images to use them? I have been looking everywhere. Thanks for the great work!

 

[RandR+]

A "hidden" feature, set the make of the keg to start with corn
i.e. Corny, Cornelius, Corn, CornOnTheCob

Anyone know where I can source some of the flow meters? I’ve looked on eBay, Amazon and general web search. All I can find are the $60 ones. I run 3-5 kegs at a time and that would be a decent investment.

 

[RandR+]

I use these, accurate enough for me
https://www.amazon.com/gp/product/B01D44N41U/ref=ppx_yo_dt_b_asin_title_o06_s01?ie=UTF8&psc=1

but you also have to buy something like these for connection
https://www.amazon.com/gp/product/B005XU0SK4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

 

[kxavier_23]

Those are a great price.

What do you mean by accurate enough?

 

[RandR+]

What do you mean by accurate enough?

I would say that if you wanted to use them for commercial measuring of flow then go with the swissflow, but for home hobby use they work great.

I haven't noticed any pours that are way off though, if I pour ~12oz it registers ~12oz
