Raspberry Pi

4/9/2016 (this stuff changes rapidly) Following instructions from I made a Raspbian image for the SD card using this file:

Once the rPi was up and running, I made sure it connected to Wifi:

Following instructions similar to I installed nodejs by downloading the latest node from

tar -xvf node-v5.10.1-linux-armv6l.tar.gz

and copying the extracted contents into /usr/local/

cd node-v5.10.1-linux-armv6l
sudo cp -R * /usr/local/

Install some dependencies for Noble:

sudo apt-get install bluetooth bluez libbluetooth-dev libudev

With nodejs installed

OsX, Linux, Windows:

npm install -g brewometer

On Raspberry pi:

sudo npm install --unsafe-perm brewometer

On the Raspberry pi, installing brewometer as a user with sudo requires the --unsafe-perm flag, you can also install as root by creating root password:

sudo passwd

then log in as root, and you can then use

npm install -g brewometer
