FarmBot Software for the RaspBerry Pi

The "brains" of Farmbot. Responsible for receiving the commands from users or the farmbot-web-app. It executes them and report back the results to any subscribed user(s).

Technical Stuff

• Written in Ruby.
• Operation scheduling data is stored in SQLite 3.
• Device status info, such as X, Y, Z and calibration data is stored via PStore
• Backups to the cloud provided by Farmbot Web API.
• Messaging happens via MQTT.
• Communicates with Arduino hardware using the farmbot-serial gem

Running in production

bundle install

If you want to enable auto restarts on crash or memory leak, run:

god -c farmbot.god -D

If you don't care about autorestarts, just run:

ruby farmbot.rb

You can find your device credentials inside of credentials.yml

Running on Local

If you're running your own local farmbot web app

FBENV=development ruby farmbot.rb

Installation

Install Ruby 2.2

This gem requires Ruby 2.2 minimum. Later versions will work fine as well. As of this writing, a Pi is loaded with 1.9.3 by default.

To remove the old version of Ruby that comes with most RPi distributions:

sudo apt-get remove ruby* --purge

To upgrade your ruby version, try this:

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
curl -L https://get.rvm.io | bash -s stable --ruby

This will take about 2 hours a standard Raspberry Pi 2.

Raspberry PI

Update the RPi, install ruby and the arduino IDE

sudo apt-get update
sudo apt-get install git-core sqlite3 arduino

Clone, install and run:

git clone https://github.com/FarmBot/farmbot-raspberry-pi-controller
cd farmbot-raspberry-pi-controller
gem install bundler
bundle install
rake db:setup
ruby farmbot.rb

Setup the device:

Go to the My Farmbot Website (or your private server) and sign up for a Farmbot account.

Then from within the farmbot-raspberry-pi-controller project directory run:

ruby setup.rb

Report problems:

We can't fix issues we don't know about. If you are having issues with setup, please raise an issue with us. This helps us identify confusing steps, common setup issues and other problems.

Arduino

You will need to flash your Arduino with custom firmware. For instructions on how to do this, see the FarmBot-Arduino github page
