Raspberry Pi Basic Setup for StrangeBrew Elsinore Thanks to Cank!
This is very kindly provided by HBT User Cank
Setup the Operating System
Install Raspbian Operating system and set it up based on your location.
Setup the Hardware
Then run this code in the LXTerminal to automatically load the One-Wire modules on start up
Open /etc/modules to edit
sudo nano /etc/modules
Add these lines to the bottom of the file /etc/modules
If you’re on a newer kernel you may need to edit your /boot/config.txt
sudo nano /boot/config.txt
Add this line
Download the SB_Elsinore_Server from git
git clone https://github.com/DougEdey/SB_Elsinore_Server.git ~/BrewServer
sudo java -jar Elsinore.jar
Choosing the GPIO Pins
See this post to make sure you use the correct GPIO pins for output and you don’t choose one that is in the default HIGH state when the Pi boots up!!!
It is highly recommended you setup a KILL SWITCH that will terminate the negative and/or the positive to the SSRs. This is a safety feature and allows you to kill the SSRs without going through the UI
First time setup
It will run some lines of code then show a list of your sensors and ask you to:
Select the input, enter "r" to refresh, or use "pump <name> <gpio>" to add a pump Type "volume" to start volume calibration Type "timer <name>" to add a timer
If you see
"java.net.ConnectException: Connection refused"
This means Elsinore is looking for OWFS (the full stacktrace will have OWFS in it) and OWFS isn’t enabled on your system. There was a bug that caused this after restarting Elsinore. This has been fixed.
If you get an error at this point saying it can’t see your sensor check out this post.
It might ask you about switching to OWFS. Say No.
Setting up the System
At this point enter the number of the sensor you want to set up and hit enter. (I only had one so I entered “1” and hit enter. It will ask you to name it. (I named mine “HLT”) Then it ask you what GPIO output the SSR is hooked up to so it knows which pin to turn on and off based on the Temperature reading or your sensor. I used “GPIO27” which is pin 13 If you just want a temperature reading, say for mash tun or cooled wort, leave it blank and hit enter. I then typed
timer Mash timer Boil pump Pump1 GPIO22 quit
It will tell you:
Updating config file, please check it in elsinore.cfg.new Config file updated. Please copy it from rpibrew.cfg.new to rpibrew.cfg to use the data You may need to do this as root Saving HLT with probe 28-00000XXXXXX Creating element of general Creating on configDoc base
Copying the config file
If it didn’t create this last file, type this:
cp elsinore.cfg.new elsinore.cfg
Running and using Elsinore
sudo java -jar Elsinore.jar
and in a web browser go to the Raspberry Pi IP address
You should see:
Stops the application
The last photo is of a breadboard that I have leds hooked to my gpio output pins for the pump(green led) and the HLT ssr(white led) when I turn the pump on the green light comes on, when I send a command for the HLT it turns the white led on based on duty cycle. Pretty sweet!!!
