Hi - I have had a BrewPi system running for a few years now using a RPi 3 and Arduino Uno. I believe this is known as the ‘Legacy’ configuration. It has been reliable and easy to program, but I would like to add a Tilt Hydrometer I got for Christmas.
In reading the instructions on Sibolwer’s GitHub, the first instructions state that I should ensure I am running the latest version of BrewPi and I am unsure how to do that. I cannot find the version using the dashboard maintenance panels and when I navigate to the BrewPi directory I see two updater tools - updater.py and update-tools-repo.sh
I am running RPi Debian and accessing the device using Remote Desktop if that makes a difference. I can access the device and see the Debian desktop and can navigate to the BrewPi folders using the Terminal Window.
Thanks, I took a look at the Brewometer Integration thread and am more confused that ever! There is talk of ‘Dockers’ and I do not believe I am using that. Also I cannot see the link to the forked code. How do I update my BrewPi code to the latest legacy code?
If I follow Sibowler’s instructions on the GitHub, I should ensure I have he latest version running (which I may have already) and then install the bluez and python-bleuz Bluetooth modules. Is there a command to determine what BrewPi version I am running?
Is there a specific post in the 450+ Brewometer Integration thread I should be looking at?
I am using Fermentrack, which controls your fermentation temperature using the brewpi hardware but also has built in support for gathering tilt hydrometer history along with the temperatures. You can set up a Fermentation schedule, keep and review old brew history, it does a pretty good job. And I think, since it’s docker based, you can run it without uninstalling your brewpi software. Worth looking into anyway. Here’s a sample of a brew in progress.
Ok, I updated BrewPi and am working through the installation steps. The installation of bluez and python-bluez bluetooth modules went ok but I have a problem with step 3 which is enabling python to query bluetooth without being root.
When I execute the following command I get an error:
sudo setcap cap_net_raw+eip $(eval readlink -f ‘which python’)
The error I get is:
Failed to set capabilities on file ‘/home/pi/which’ (invalid argument)
The value of the capability argument is not permitted for a file. Or the file is not a regular (non-symlink) file.
OK. I am answering all my own questions here. I found my stupid Linux noob error. The ‘which python’ part of the command must be in back-quotes which python. That works.
I ran the TiltHydrometerTest.py script and it correctly found my orange Tilt. Life is good - at the moment!
