PFC

Personal food computer driver. A work in progress.

Install on Raspberry Pi

Install the latest version of Node. Todo this, either search for an article to help walk you through it or run the following:

 https://nodejs.org/dist/v8.9.1/node-v8.9.1-linux-armv7l.tar.xz
-xvf node-v8.9.1-linux-armv7l.tar.xz
ode-v8.9.1-linux-armv7l

Then copy to /usr/local:

 cp -R * /usr/local/

Test that's it's working with node -v.

Once node.js is working, you're ready for the rest:

 apt-get update
 apt-get install wiringpi usbrelay git i2c-tools
clone https://github.com/CommonGarden/PFC
FC
install
 node pfc.js

Connecting to your Grow-IoT instance

By default, the example driver connects to https://grow.commongarden.org.

To change this see the bottom of the example-device.js file. It currently reads.

owHub.connect({
host: 'grow.commongarden.org',
port: 443,
ssl: true
;

For development it's easier to simply connect to you local computer. Find your computer's IP address and change the host, port, and ssl options:

owHub.connect({
host: '10.0.0.198', // The ip address of the host
port: 3000, // The port you are running Grow-IoT on
ssl: false
;

Run on boot

Once you're happy with your driver you'll want to start it on boot in case your device looses power.

Install forever globally.

 npm install forever -g

Then create a new text file in/etc/init.d/:

 nano /etc/init.d/grow

Paste in the follow (note this assumes you installed Grow-Hub in the home folder for a user named pi):

in/bash
c/init.d/grow
rt PATH=$PATH:/usr/local/bin
rt NODE_PATH=$NODE_PATH:/usr/local/lib/node_modules

 "$1" in
t)
 sudo forever --sourceDir=/home/pi/PFC -p /home/pi/PFC pfc.js

)
 sudo forever stop --sourceDir=/home/pi/PFC pfc.js


 "Usage: /etc/init.d/grow {start|stop}"
 1


 0

Make it executable with the following command:

d 755 /etc/init.d/grow 

Feel free to test it:

etc/init.d/grow start/stop

If all goes well, make it bootable:

 update-rc.d grow defaults

To remove it from boot:

 update-rc.d -f grow remove

One last step, edit the /etc/rc.local file.

 nano /etc/rc.local

Insert the following line before exit 0:

etc/init.d/grow start

Reboot and your pi should start into the Grow-Hub driver.
