Brewometer integration


#451

Do you see any changes on your UI?

Are you able to see any Tilt related lines in your stderr/stdout logs?


#452

UI didn’t change and there nothing in the logs about the Tilt as far as I can tell.

I’ve gone back to TiltPi in the meantime since I have something fermenting I want to keep an eye on, but can try again some more this weekend/next week.


#453

Are you sure you managed to change the files inside the container/in the right spot? The other thing to check is that re-started the script (or container) after making all the updates.


#454

Sorry if this is the wrong place … but I just installed this successfully on the Legacy/Arduino system I have been running for the last 2 or 3 years … and wanted to say many many thanks to Both Elco (for conceiving of, and putting together such awesomeness) and sbowler (bloody legend) for their respective parts.

For something I spent less than AU$100 on 3 years ago, plus the recent additions/replacement of a Rpi3 and a new Tilt, … I can stare right into the heart of the beast now, and see what it’s really up to (noise notwithstanding)

It’s an awesome system for me and my shed, love ya work.


#455

Help, please. My BrewPi SD card corrupted and I did not have a copy of the card after installing the Tilt stuff (stupid me). I have rebuilt using the legacy BrewPi as I am lost with the new BrewPi and containers, dockers , etc. However, your readme at GitHub is missing the instructions on loading/installing to my machine. Can you let me know what I should be doing? “sudo apt-get install ?..?”

#456

Hey, this is awesome! I’m not really a coder, I have just installed everything (on Legacy) following steps, but I would love to know how you did this. But I don’t know what all the code you added was.

to beer-panel.php I added the “lcd-line-4” line:
47%20PM

But after that, I am lost. I am unclear what to add to the main.js file. I found the refreshLCD function, but what would populate that with the data?

I am also unclear what to add to the brewpi.py file or where within that file.

Having the Tilt gravity in the LCD panel would be awesome for me! I greatly would appreciate any help on this!
Thanks

#457

After struggling a while with a iSpindel I just received my Tilt. I got it running using a the TiltPi.
But I would love to have the readings from the Tilt in the brewpi graph. I can not get this working. I completed all the steps from the readme (https://github.com/sibowler/brewpi-brewometer/blob/master/README.md).
I use brewpi in the docker configuration and I updated brewpi before starting with the code below:

sudo apt-get install python-scipy python-numpy
sudo apt-get install bluez python-bluez python-scipy python-numpy libcap2-bin
sudo setcap cap_net_raw+eip $(eval readlink -f `which python`)
root@raspberrypi:/home/brewpi# python /home/brewpi/brewpi-brewometer/tiltHydrometer-test/TiltHydrometerTest.py    
	(I get a reading from the tilt!)

root@raspberrypi:/home/brewpi# cp -r /home/brewpi/brewpi-brewometer/brewpi-web/. /var/www/html/			
	(I can confirm that the items were copied)
sudo chown -R www-data:www-data /var/www/html/
root@raspberrypi:/home/brewpi# cp -r /home/brewpi/brewpi-brewometer/brewpi-script/. /home/brewpi/		
	(I can confirm that the items were copied)
sudo chown -R root:root /home/brewpi
	(here I used root:root instead of brewpi:brewpi)

I refreshed the browser en started the script again, even after restarting the brewpi container I dont see the graph.

update 14-10
I found out that brewpi-web should be copied to www-data /var/www/html/ and not to www-data /var/www/
Now something has changed in the brewpi graph. I now see all the tilts, but not yet the reading from my tilt.

Does anybody have an idea what goes wrong?


#458

Somehow I got it working now. Below some problems:

  • selecting a value from one of the tilts is not possible in the legend, values from brewpi work fine.
  • the actual values from the tilt are not visible in the legend, values from brewpi are visible
  • the legend is way too long so the area with the status is in front of the legend
  • the scaling of the tilt gravity data is not correct. The gravity value is in the same scale as the temperature, so a value of 1 to 1.1 on a scale from 1 to 22. Only with zooming the graph is readable

I found the problem. I needed to clear my cache in google chrome.


#459

Sorry to took so long to check out your reply. I stepped through the README but still get errors.

Firstly "python-scipy : Depends: libstdc++6(>= 4.3.0) but it is not going to be installed

I tried installing libstdc++6 and am told that it already installed (6.3.0-18+rpi1+deb9u1) and that it breaks python-scipy

@sbowler, I made all the file / directory changes but when I go to run the TiltHydrometerTest.py I get this:

root@a578f97090d0:/home/brewpi/tiltHydrometer-test# sudo setcap cap_net_raw+eip $(eval readlink -f `which python`)
root@a578f97090d0:/home/brewpi/tiltHydrometer-test# python TiltHydrometerTest.py

I feel I’m missing something simple.


#461

Hey I have hit the same issue, by the looks of things the latest version of docker now includes a device flag, so I think you need to include the Bluetooth device in the docker start up script. The examples I saw were for USB Bluetooth dongles not built in Bluetooth. But I can confirm my docker images does not have any bluetooth devices. Run hcitool dev to check. I’ll post again once I figure out what to do.


#462

Ok so I manged to get access to Bluetooth in Docker by starting the docker image with --net=host.
So “docker run -d --name brewpi --net=host --privileged -p 80:80 -p 81:81 -v ~/brewpi-data:/data -v /etc/timezone:/etc/timezone -v /etc/localtime:/etc/localtime --restart always brewpi/brewpi-raspbian”
I didn’t get any data returned by the test scan but the error went away.


#463

Ok so you also have to switch Bluetooth on… I did this on the host.

  • Type sudo bluetoothctl then press enter and input the administrator password (the default password is raspberry ).
  • Next, enter agent on and press enter. Then type default-agent and press enter.
  • Type scan on and press enter one more time.
