[Version 2 Release] RaspberryPints - Digital Taplist Solution

[day_trippr]

Then again...holy cow!
Clearly those four wall hangings were posted well before my reply but I never saw a trace of them prior to this moment
Anyway...Lee will have to have a look through that morass...

Cheers! (And, Yikes!)

 

[day_trippr]

On other fronts...folks with flow meters might appreciate this paradigm: wondering exactly when a keg will kick vs the remaining volume shown before that last pour, and having it blow foam at exactly 0 ounces remaining.

Cheers! (I love this rig! )

Greetings, @Suchidog, and welcome to our wee corner of Home Brew Talk
Apparently the dump has been cleaned as I see no trace of one...

Cheers!

Thanks @day_trippr

I think an admin had to approve my log posts as they were so large!

 

[day_trippr]

lol! Ok, that makes sense. Gotta be a first, so you have that going for you
I would allow Lee to chill tomorrow but expect he'll be on this soon...

Cheers!

Ok done that, where do i find the debug file?

specifically the script couldn't find /var/www/html/test.php using Apache because Apache failed to start after installation because port 80 was in use. Is this a clean install or do you have a different web server installed?​

Thanks for the reply @RandR+

I already have Fermentrack running on the same Raspberry Pi. Is there a away around this issue?

How do I find the default username and password to log into the admin page? I installed randr’s script.

 

[RandR+]

Is there a away around this issue?

I'm not sure of the top of my head, I think there is a different thread someplace on it but not sure.

Technically there should be a work around by adding the raspberrypints web home to the web server config but I don't know how to with fermentrack. Its on a list to look into and add into the install script

 

[RandR+]

hanks, i've checked there bu

sorry run the following from the terminal
sudo /etc/init.d/flowmon restart

then check the log

 

[RandR+]

How do I find the default username and password to log into the admin page?

It prompts you for a user and password. but by default the user is admin and no password (type admin in the user and try to login)

If that doesn't work Ill walk you through the terminal commands to find and restart

That didn’t work.

Never mind.... it worked. I left username and password blank and just clicked log in. Feel like a dummy.

 

[Bigs166]

Randr: I like the new beer srm images and all of the updated admin stuff.
If I run your new script with the curl L.... line will I still retain all the changes I’ve made? Fonts, sizes, etc? Or will I need to redo all of this?

 

[Tobor_8thMan]

Thanks for the reply @RandR+

I already have Fermentrack running on the same Raspberry Pi. Is there a away around this issue?

Seems to me there are a few ways around this issue. I take it Fermentrack is auto starting. Do you want both Fermentrack and Raspberry Pints running at startup? If so, modify the startup bash script to launch RPints.

If desire one or the other, modify the startup bash script to ask what is desired to run and then launch either Fermentrack or RPints based on the reply.

 

[DaniFilth]

sudo /etc/init.d/flowmon restart

Thanks, i'm now getting this

2019-12-26 19:11:20 RPINTS: [Errno 2] could not open port /dev/ttyS0: [Errno 2] No such file or directory: '/dev/ttyS0'

Basically indicating the path to /dev/ttyS0 isn't found. At what path is the script being run? May simply need ../dev/ttyS0

 

[delanobrews]

Has anyone gotten a wheatstone load cell configuration with an hx711 amplifier working with remaining keg volumes? It appears to be an option but may still be being worked on?

I have the digital menu all up running, even have hx711py running and showing me values in the terminal. Just not sure how to get those values to show in the web interface.

 

[Suchidog]

Thanks @RandR+

I will check back periodically to see if you have had the chance to look into it

I created an option to display the new SRM images, but if you changed any file that was updated then the updates would need to be wiped out to apply my changes. In fact the update might fail because you have manual changes because of the way Git does it.

I would make a copy of the directory then run the update and then compare to see if any changes got wiped out

 

[RandR+]

No such file or directory: '/dev/ttyS0'

Was there an error in the install script? What Version of Raspbian are you using?

If you open the Arduino IDE can you select port ttyS0 under Tools->Serial Port

 

[RandR+]

Just not sure how to get those values to show in the web interface.

I did the code for that but didn't actually have them to test it. There is a configuration page for them that you can setup what pin is what tap. I will have to go back and review as I don't remember very much of it.

Sounds good. I’ll back up and give it a try. Thanks a lot!

@RandR+ In FlowMonitor.py starting on line 559 (class LoadCellCheckThread). It looks like there are two commented sections under "def tare" and "def getWeight" that are still listed as #TODO.

I have load cells calibrated outside my keezer weighing a semi filled keg with little to no drift. If it would help, I can either give you remote access to the pi running your latest version or can box the hx711, load cells, and platform and send it to you for testing.

 

[RandR+]

It looks like there are two commented sections under "def tare" and "def getWeight" that are still listed as #TODO.

Yep I just remembered I just put in the logic to be able to get weight but not the actually logic to poll the load cells.

Remote access will be useful once I get the code for the HX711 done probably a couple of days depending on my work load, when I can do is send you the update when its ready then you test and if any issue arise then we can start remote connection talks

Rock and roll! I got excited after loading up your version and saw the load cell section in FlowMonitor.py. I have a few more sets of load cells coming and trying to put something together that can monitor the 8 taps in the keezer that looks prettier than a few numbers kicked out of a cli.

Randr:
How do I completely remove the ‘color beer name tasting notes abv drinks remaining’ line ?

 

[RandR+]

‘color beer name tasting notes abv drinks remaining’ line ?

in includes/beerListTable.php comment out or delete line 12 to 69 (<thead> to </thead>) ill parametrize it with the next release

 

[DaniFilth]

If you open the Arduino IDE can you select port ttyS0 under Tools->Serial Port

Aha, it seems at least that i can't open Arduino IDE tried installing it but nothing has changed

Thanks dude.

Arduino IDE tried installing it but nothing has changed

Can you see the ttsy0 port under tools -> Serial Port?

 

[Deric]

Been looking for a simple-ish RPi project to get my feet wet... Putting together a shopping list/cart. The RPi 3B+ says it has built in wifi - do I still need a USB wifi adapter? The parts list calls for a SD card - I believe the 3B+ uses a Micro SD card - is that correct? Last question for now... If I get a small RPi touchscreen will I still need a USB keyboard/mouse? Can I use my PC to setup and then get by with the touch screen?

Thanks!

 

[DaniFilth]

No the program won't open at all

 

[LBussy]

I used to command curl -L https://raw.githubusercontent.com/rtlindne/RaspberryPints/master/util/installRaspberryPints | sudo bash

and seemed to get a long way through the install process as per the following log but got an error. Is anyone able to point me in the right direction? Thanks in advance.

Just guessing by the name similarity: I suspect you have Fermentrack installed? If so you're a no-go and without some knowledge you won't be able to get both running at the same time. Fermentrack runs nginx and RPints uses Apache2.

 

[RandR+]

No the program won't open at all

Hmmm, usually the program comes preinstalled and working. Where did you get the Raspbian install files?

Just the raspbian site, maybe i'll just redo it all again

 

[scaglikm]

Okay new to this. Can someone point me towards the best place to get started (this thread is a bit overwhelming). Thanks in advance!

 

[scaglikm]

Okay found the instructions on the RaspberryPints website. Got to an error (unzip: cannot find or open RaspberryPints-2.0.1.zip, RaspberryPints-2.01.0zip.zip or RaspberryPints-2.0.1.zip.ZIP) when trying to figure out how to unzip it. Any ideas?

RPints is dead as far as the original project goes, although there are some folks supporting branches of it (that's not bad, just saying the website you hit is not a good source of info.) Here's one link in this thread. I'm not claiming one branch is better than the other, this was just the first one I saw going backward.
