[Version 2 Release] RaspberryPints - Digital Taplist Solution

[GBPD80]

Good evening, I'm new to Raspberrypints version 2 and have just installed RandR+ version. THANK YOU very much for sharing RandR+ ! So far so good I have added my beers successfully and will be adding a motion sensor and 6 flow meters when they arrive in the mail. Until then I have a question regarding how to increase the font size for the beer name and style? As you can see from my picture my beer name text is small. I would like it much larger if possible. I've searched through many postings and can't find an answer to my question, this is not to say I missed it which i'm sure I might have. Anyways, any help would be much appreciated. Thank you!

Thank you!!!
Unfortunately I'm working 12 hr shifts the next 4 nights so when I get a chance I will give it a try. I have no programming skills and new to raspberrypints so bare with me I'm sure I will need some help .
How do I access the style.css file to make these changes?

no programming skills required

those files listed above are located in /var/www/html directory on the pi. Go into pi GUI and double click files to edit.

perhaps make a backup of the files you edit beforehand in case something goes wrong.

 

[GBPD80]

Thank You!!! I found the files. I tried to edit and rebooted the system and no change. I must be doing something wrong. Line 448 I increased from .65em to .95em and no change. So I'm guessing I'm not doing this correctly. What I'm hoping to do is increase just the font size for my beer names so you don't have to squint to read them. I'm sure I will need to make an adjustment to the height of the columns to fit all 6 taps on one screen without having to scroll. Help here would be much appreciated as well. I am now able to remotely connect to my raspberrypints through teamviewer so when I have a free moment while working I can logon and make changes. Thanks again for all the help!!!!!! Cheers!!!!

Try deleting internet history/cookies/etc and then reloading. Can also try loading in private mode in the browser.

edit:
Can also increase font size by pressing ctrl + in the browser window

teamviewer lets you do this

 

[GBPD80]

Thank you! I will give that a try deleting what you mentioned.
Are you suggesting to open the style.css file in private mode in the browser or raspberrypints? Not sure how to do either because currently when I reboot pi it automatically goes into Kiosk mode. I usually alt F4 to close out of rpints make changes then reboot because I don't know any other way of reopening rpints.
So sorry for all the questions I'm learning this as I go and really appreciate everyone's patience's and help!

 

[GBPD80]

Just cleared all browsing history, cookies etc. as well as set to automatically delete when I close chromium

Sorry, i meant try reloading the webpage of rpints in private mode. I may be talking above my pay grade here, but i know that internet browsers save some things (at least images) in a cache so it doesn’t have to download them over and over (speeds up loading webpages). So when you make changes to rpints , you won’t always see them take effect until you delete/clear history/cookies/etc in the browser. The alternative is to just open a private tab in the browser and go to the rpints page (local ip of the pi). I’m not sure if fonts are the same way.


Also try going to the rpints webpage and pressing ctrl + a couple times. This increases font size.

I’d disable kiosk mode and just run the browser in full screen (f11). But I would have to do some googling on how to do this!

 

[fun4stuff]

Is the font bigger when you reload rpints?

 

[GBPD80]

No change after reload Bananas!
I did use the Ctrl + to zoom in but then I need to scroll down to see all 6 Taps.
I will google as well how to remove kiosk mode.
Thanks again.

 

[GBPD80]

Ctrl + works like I said but then I need to scroll.
I'm sure there is a way to get what I'm looking to do, I've seen other posts with a horizontal screens and 6 taps with larger fonts. I must be doing something wrong I sure.

so you can figure out what you need to edit by right clicking what you want to edit and choosing inspect. This will tel the file and line number to go to. You can even change it in inspect mode to see how it looks.

So when i right click the font of the beer name it tells me:

see attached pic
In styles.css
go to line 466
Change the number in “1em Georgia”. Try 1.5.

 

[GBPD80]

I can't right click on the font of the beer name. When I do nothing comes up. I think I need to figure out how to stop loading in kiosk mode.
i will try and change your suggested font now.
Thanks!

Yahoo finally got it to work!!!!! I ended up going into the sudo raspi-config and changed my boot option to auto login desktop. then holy Toledo the fonts were HUGE! ended up deciding on font: 3.0em Georgia
THANK YOU for the Help! If I get a chance tomorrow when I get up and before I head back to work I will look at in on my monitor vs remotely right now. Might have to make a tweak or two but it is working now! Thank to your help especially fun4stuff !!!!

I installed the RandR+ version using the installation script, everything was working just fine for a few weeks. Now my temperature probe is showing the temperature from 17+ hours ago, it has apparently stopped logging. I have tried restarting the flowmonitor service, I have tried rebooting, and I have powered down and re-started the R Pi/Alamode with no success in correcting the issue. When I go to the hardware section, the temperature probe is showing. If I try to access the temperature history, I get a blank grey screen (see the attachment). Any suggestions?

 

[LBussy]

@RandR+: I was poking around and noticed a new message: sendUpdateCount(). What's the difference between that and sendPulseCount()? It seems exactly the same so when do you use one vs. the other?

 

[GBPD80]

Glad you got it figured out!

Yes I'm now working on figuring out how to do the following:
1. Increase the size of my beer pictures ieLemon picture)
2. change the color the color grey to white for the SRM, ABV, Keg columns this would make it easier to read.
Trial and error but no luck so far, any ideas or can you point me in the right direction?
I attached a picture of how it look now. Not as clear since I'm remotely connected to my raspberrypints.

Quick question regarding the BeerlistTable.php I have attached a picture of my line 125 I don't have anything on there. Am I suppose to copy and past your code there? See attached photo
Also, I tried to make a change here and I got an error message. see attached photo.
Thanks again for all your help!

Your looking for a line that says this and it may not be line 125 on your beerlistTable,php file. (Change the height and width as shown in bold)

if(count($imgs) > 0) $style .= ($style != ""?";":"").'background:url('.$imgs[0].') no-repeat center; background-size:cover; -webkit-border-radius:0px; -mox-border-radius:0px; height:100px; width:70px';

Edit- As for your error message try typing this in the terminal window. If that doesnt work then you will have to ask RANDR+
sudo chmod +777 /var/www/html -R

 

[troyp42]

My guess it will work until a restart, but if it stops measuring pours, check the admin -> log page for the latest event that happened in the code

So it worked all week then stopped again. The Rpints log said this after I rebooted

If you select your text for SRM etc and right click the highlighted text and choose inspect element from the drop down menu the inspector will open up to thee right of your window. It will show you what line of the css file you need to edit. Then you just open the css file in Geany and edit that line. It will be similar to my examples shown in my post but may be different line numbers to you.

I type the command like this:

maybe it works both ways?

Now my temperature probe is showing the temperature from 17+ hours ago, it has apparently stopped logging. I have tried restarting the flowmonitor service, I have tried rebooting, and I have powered down and re-started the R Pi/Alamode with no success in correcting the issue. When I go to the hardware section, the temperature probe is showing. If I try to access the temperature history, I get a blank grey screen (see the attachment). Any suggestions?

I removed the Alamode from the system, and only have the Raspberry Pi 4B (Buster) operating to try to reduce possible error points in the system. I replaced the temperature probe with a new probe, no change. I re-installed Raspberry Pints (RandR+ version) using the installation script, the new temp probe is recognized but no temperature information is shown on the main screen (yes, I have the configuration set to use the probe and to display the avg temp on the screen). The Temp history now shows data, but I only got good readings for 2 minutes, then the temp line dropped to 32 degrees and one hour later the readings stopped completely. This is the same behavior I had originally, the temp dropped to 32 degrees and the readings stopped. It also appears the temperature graph is being rendered backwards, with new readings to the left instead of the the right. I'm about ready to just give up.

 

[day_trippr]

Well, at least it's looking like a RPi-side issue instead of the Arduino.
How are you powering and cooling the RPi4B?

Cheers!

 

[esdill]

Cheers!

Powering the RPi with an "official" Raspberry Pi power supply, 5V/4A via the power in port. Cooling via heat sinks on the chips, but the RPi is installed inside a case. I have tried running it outside the case and have the same issue. It is currently inside my keezer, with the cover off the case, at 38 degrees F ... if it's not cool now it will never be cool.

 

[day_trippr]

Ok, that seems legit enough.
So maybe let's look at the probes: I may have missed it along the way, but how are you powering them, and do you have a pull-up on the data line somewhere in 2K-5K range to 3.3V?

I wonder if the One-Wire bus is getting hung, and if there's some kind of status one can pull out of the bus master (the RPi4B) after the probes go missing...

Cheers!

I have the red from the probe connected to 3.3V on the GPIO header (Pin 1), the yellow from the probe on GPIO 4 (Pin 7), a 4.7K resistor between Pin 1 and Pin 7, and the black from the probe to ground on Pin 6 of the GPIO header.

 

[day_trippr]

Reboot with the sensor(s) attached, pull up a console session, and see what this command does:

ls /sys/bus/w1/devices/

Then run it again after the sensors have "disappeared".
We likely know what will happen but might as well confirm it...

Cheers!

fwiw, the "good" response should take this form:

pi@rpints ~ $ ls /sys/bus/w1/devices/
28-00000689f325  28-0000068a0cee  28-0000068a2030  28-0000068a3443  28-0000068a8e2b  w1_bus_master1
pi@rpints ~ $

Note that system name is rpints...and I have five sensors attached to it...

OK ... I rebooted, ran ls /sys/bus/w1/devices and got this:

28-0308979456bf w1_bus_master1

Temp was flat lined at 32.00 for multiple readings, I moved the probe out of the keezer and got 3 readings of 79.70, 80.78, and 81.32 one second apart, then it flat lined again at 32.00 for multiple readings.

The second run of ls /sys/bus/w1/devices gave me only this:
w1_bus_master1

 

[day_trippr]

fwiw, this table shows how a 32°F (0C) reading happens: somehow the bus master believed the sensor returned all zeros.

Also, there's a different, "not normal" response of 185°F (85°C) if the sensor is not given sufficient time to complete a "Convert T" command and place the result in the scratchpad buffer.

wrt the all zeros, unless the RPi is doing CRC checks on the returned data there's no way to know for sure who is at fault here, but generally I'd suspect something about the sensors...

Cheers!

Ok, thanks for the help! I'll keep trying different sensors ... and if that doesn't work I'll just walk out to the porch and look at the Inkbird to see what the keezer temp is (I wanted the convenience of looking from inside on my PC each morning, but I guess I can use the exercise).

 

[day_trippr]

Well, give @RandR+ a chance to digest all of this, maybe he'll come up with something

Cheers!

Well ... I replaced all connections between the probe and the RPi and now have the probe directly connected to the RPi GPIO header (I had some terminal strips for the transition from inside the keezer to outside the keezer, I have eliminated them) ... and now I am getting good, regular temp readings. The only remaining issue is that the temp reading is not displaying in the upper right corner like it should, even though "Show Avg Temperature on home screen" is set to "on".

I have a hardware question: How are you mounting your RPis & Arduinos? In cases? In the kegerator itself?

I'll allow you plenty of time to determine if your changed sensor wiring remains functional
As for what shows up in the gui, hopefully @RandR+ will have some advice. I'm still running "R'Pints Classic" here...

Cheers!

Want a boundary case?

Everything needed is here, including power and cooling. There's an RPi2B under that Alamode hat, and an Uno R3 to the right. The former deals with flow meters while the latter controls the keezer compressor.

I mounted drawer slides in the keezer dolly...

If I need to get inside the control unit (and over the years that has happened on occasion) it pulls right out and the lid pops off.

6 flow meters, five temperature sensors, power to stirring fans, desiccant blowers and the tower cooler, cables to the display, speakers, motion sensor, Bluetooth and mini-KB dongles...yup, that's a crapton of wiring back there...

But in front...it's all quite serene, actually

Cheers!

That's incredible.

Yeah, a wee bit over the top
I chalk it up to the thrilling liberation of unchecked implementation after over four decades of principal design engineering work under some of the biggest "management" nimrods in the big-time computer industry.

I'd never actually advocate for a quarter of that, but if you're looking for tips, don't stuff active electronics inside a fridge or freezer unless you can both hermetically seal them from condensation while also providing for cooling. That's a fair challenge right there that I didn't want to test, and I did have that dead space in the dolly to exploit (btw, the other module to the right of the controller houses a power supply for all of the fans and a 30A relay that switches the compressor under command of the controller)...

Cheers!
