[Version 2 Release] RaspberryPints - Digital Taplist Solution

[RandR+]

What the heck?

sounds like user sound settings since sudo is a different user then pi.
if those commands work from the terminal then it should work from the python unless something else is triggering the screen to wake up and not the motion detector.

in Config.py if you set
config['flowmon.debug' ] = True
then it will log out when motion is detected.
You may want to switch dispatch.debug to false to reduce logging when looking for motion detection issues.
config['dispatch.debug' ] = False#True

I was trying to find the threshold that triggers the kicks as it is way too low for Swissflow meters.

i wonder if your flow is too strong, kicks are triggered slightly differently than pours. The pin has to go high-low-high in the same millisecond to count towards a kick then the kick count has to reach the threshold. Intertwined with the kicks would be pours counts which is probably why you are seeing them back to back.
Maybe look at your old sketch to see how it counted pulses, in the new one its in pollPins, maybe just removing the check for same millisecond (~line 340) and count everything as a pour tick (since your ignoring kicks anyways).
I know the original uses interrupts to count pulses but i found that doing that would mess with the timing of doing other things like flashing the LED and RFID checking.

i wonder if your flow is too strong

I believe you hit the nail on the head: I've been "testing" the meter functionality by blowing through one of my spare meters I use for this kind of testing. And after some experimentation I was able to "pour" a little over 12 ounces without triggering a kick. Calibrated breath

I changed config['flowmon.debug' ] to True and config['dispatch.debug' ] to = False and restarted the flowmon process. Noticed it actually reflashed the Alamode this time (hadn't seen that before so I guess that switch enables that stuff to go in the log) and when it was done the log file started growing quicker than before. In the mass of "status checks" with corresponding "sending status" lines I found a Motion Detector line that corresponded to an intentionally blanked screen snapping back to life:

2023-03-21 18:05:46 RPINTS: StatusCheck;
2023-03-21 18:05:46 RPINTS: Sending Status;N;-1;0;0;0;0;0;0;0;|
2023-03-21 18:05:46 RPINTS: Motion Detector MD-Motion Detected Motion
2023-03-21 18:05:46 RPINTS: StatusCheck;
2023-03-21 18:05:46 RPINTS: Sending Status;N;-1;0;0;0;0;0;0;0;|
2023-03-21 18:05:46 RPINTS: StatusCheck;

So it's definitely R'Pints that's waking the screen. It's just not doing the rest of the stuff

Cheers!

phpmyadmin question: it was installed and I can get into the gui but it has no idea where any databases are and on the Databases sheet it has this:

Not that I want to create a database - I just want to link to one.

I have older versions of phpmyadmin running on numerous nodes and they all have a link to their respective databases and I can paw through them at will - but I don't remember doing anything special to get them to find their RaspberryPints databases. Is there a trick I'm missing?

Cheers!

 

[RandR+]

In the mass of "status checks" with corresponding "sending status" lines

do you still have the log(msg) line in FlowMonitor.py? If so remove it, status check should be suppressed and not log.

R'Pints that's waking the screen. It's just not doing the rest of the stuff

I figured out the problem, the sound file setting was never passed to the thread so it really wasnt trying to play a sound. But it should have turned the LED on for 1 second. I committed my fix for FlowMonitor.py for you to take. I forced the command outside that thread and it played but when I tested with the thread it did not so Im 100% convinced it will play but if you could test and let me know.

no idea where any databases are and on the Databases sheet it has this

what user did you use to login with? Try your RPints user if you didnt use that.

 

[RandR+]

But it should have turned the LED on for 1 second

I figured it out. Besides the soundfile i forgot to pass the rest of the motion sensors parameters. I will have an update later today when i get a chance to make and test the changes

 

[day_trippr]

Awesome! I just got home so I have to catch up to your other posts after dinner...

Cheers!

 

[day_trippr]

Ah yes, I did. Good call. Commented that line out and et voila! Much tighter log file now
No rush on your next update, I'm in the middle of painting some stuff in the brewery...

Cheers!

 

[RandR+]

No rush on your next update

when you have a chance the next update is committed

 

[day_trippr]

I'm running on fumes and would probably brick my RPi if I tried updating tonight.
Should be able to give it a fully rational try in the morning

Cheers!

 

[day_trippr]

fyi, I lost my system boot drive a few days ago. After some hair-raising moments it appears I didn't lose a bit of decades of data which is backed up in various places, but I did lose the OS and the entire application suite I had accumulated since the nineties, really. I have been recovering everything piece by piece as I build a fresh system disk, and re-installing desktop Github and fetching down the updated R'Pints kit is on the "to do" list. Hopefully I'll get to that soon...

Cheers!

The raspberrypints.com website seems to have an error or has been retired.

Is there anywhere with the parts list other than the raspberry pi so that I can get the flow meters and other parts needed?

I have Rpints working without flow meters but think I'm up for the next challenge.

I was discussing the Rpints with the owner of a homebrew shop and he said impossible to measure flow without meters causing cavitation and beer to pour as foam. I'm pretty sure this thread being so long is testament to the fact the system does work.

Thank you

 

[day_trippr]

My half dozen SwissFlow meters in service since Memorial Day 2014 say said shop owner is sadly misinformed

The parts list is quite small:
- one RaspberryPi, preferably a quad core version, with power supply and SD card to fit. [edit] A single core version will be slow, a dual core will actually work just fine and is what I have running my brewery. But the quad core will be useful for more stuff if you get involved with chambers and controls. I run a keezer and three BrewPi "classic" refrigerator temperature controllers from one dual core RPi 2B.

- one Arduino sporting a 328P or equivalent microcontroller, such as an UNO R3 or a NANO, with an appropriate power supply
- one flow meter for each faucet, preferentially SwissFlow SF800, with appropriate fittings to connect at beer QD and tap line.
- recommend one 240 ohm pull-up resistor to Arduino +5V for each meter. A 1/8th watt resistor or fatter is fine.
- a display of some kind

fwiw, I have a RAR archive of the original Raspberrypints.com web site parked on my Google Drive. You can download it and expand it in a folder and access it with a browser...

Cheers!

Thank you so much, I'll get ordering and reading the details.

 

[beren]

Where do you prder the flow meters from and about how much do they cost? I can't find anything online but some datasheets.

 

[day_trippr]

Order direct from the manufacturer at Swissflow | SF 800 Low Pressure Infrared Flow Meter
Or try using one of the inexpensive meters associated with Arduino and Raspberry Pi, like meters sold by Digiten

https://www.amazon.com/DIGITEN-Sensor-Switch-Flowmeter-Counter/dp/B00VKATCRQ/
or one like this which was/is popular with the Kegbot folks...

But make sure whatever you use you can thread on the appropriate fittings to match the beer line used...

Cheers!

 

[DuncB]

and that it's not a variant with any brass in it.

Quite the price difference I had noted between the swiss and the alternatives. But from reading appears that the swiss flow might be more accurate than the adafruit type.

 

[day_trippr]

Yes, you're paying for accuracy with the SF800.
The payoff is when a keg kicks within a pour of expected

Cheers!

I have had no luck trying to update my windows server install to the newest version. Is there an installer I can use for windows to just start fresh?

 

[day_trippr]

"Windows Server install?"
I may be missing something (for which you can punish me later ) but the server/back-end side of R'Pints is written essentially for Debian Unix...

Cheers!

 

[Thorrak]

WSL?

 

[day_trippr]

Ah - maybe. Funny, I installed that forever ago to enable ripping some DVDs but otherwise didn't find much use for it...

Cheers!

 

[Beekeeper]

WSL?

the inverse of WINE? You might be posting in the wrong forum.

 

[Thorrak]

the inverse of WINE? You might be posting in the wrong forum.

Exactly. Not sure, but you might be able to run RPints in WSL. I've never tried it, but in theory...

 

[Beekeeper]

Exactly. Not sure, but you might be able to run RPints in WSL. I've never tried it, but in theory...

(Sorry. I was only joking. Will now migrate to a remote corner.)

 

[Thorrak]

(Sorry. I was only joking. Will now migrate to a remote corner.)

WSL is one of those things I'm always shocked when people have heard of it


(22 minutes later edit) ...****, I just got it.

 

[RandR+]

Is there an installer I can use for windows to just start fresh?

My installer is meant to setup Linux with the correct software. But I do use windows for all my webpage development but use Pi for the actual flowmeters since the python was designed for the PI's GPIO. There may be a way to install arduino on embedded windows and modify the python as needed.

They way I setup windows is Enable IIS and install PHP.
Put RPints in the inetpub\wwwroot folder, usually under its own directory so other sites can be served alongside of it.
Open IIS, expand the tree till you see RPints, right click and hit convert to application.
Confirm index.php is a default webpage
Open browser to <servername>\<RPints Folder Name>

 

[RandR+]

This repeats as long as the PIR is exposed...

Fun fact, if you dont read a notification HomeBrewTalk doesnt send you any more emails about notification until you read it so I was a little late seeing this

I see the issue, and comitted the fix if you get latest again

 

[day_trippr]

No problem, I was busy building a new boot drive for this workstation anyway

So I did the update in place, as this witnesses...

...and I cannot find a single file with a date newer than my April 2nd edits to the config.py file to enable flowmon logging, so I don't think the update actually "updated" anything.

I'll see if my Github desktop can find anything but what files were supposed to change?

Cheers!

 

[RandR+]

but what files were supposed to change?

RaspberryPints/FlowMonitor.py at master · rtlindne/RaspberryPints is the only file that changed.

Did you hit Update or Get Latest RPints? Update just runs the update.sql script, but Get Latest RPints gets the latest from GitHub
