Raspberry Pi Basic Setup for StrangeBrew Elsinore

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

w1-gpio
w1-therm

If you’re on a newer kernel you may need to edit your /boot/config.txt

sudo nano /boot/config.txt

Add this line

dtoverlay=w1-gpio,gpiopin=4

Then reboot

sudo reboot

Download Elsinore

Download the SB_Elsinore_Server from git

git clone https://github.com/DougEdey/SB_Elsinore_Server.git ~/BrewServer

Switch directories

cd ~/BrewServer

Run Elsinore

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 &ltname&gt &ltgpio&gt" to add a pump
Type "volume" to start volume calibration
Type "timer &ltname&gt" to add a timer

Initial Setup

Some errors

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

Setup an output

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

Then run:

sudo java -jar Elsinore.jar

and in a web browser go to the Raspberry Pi IP address

192.168.1.XX:8080/controller

You should see: Web Interface

Stopping elsinore

Stops the application

Ctrl-C

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!!!
