sabjorn / huecomposer Goto Github PK

hueComposer is a python script meant for running on a Raspberry Pi 3. It is under ongoing development for use by Robert Youds in an installation piece.

The basic goal is to provide a mechanism to drive 30+ Philips Hue lights.

A USB stick containing images is read by the script. The pixel values for each column of an image are stepped through in time, with the pixel values of each row being transmitted to each individual Philips Hue.

On a Raspberry Pi running Linux Debian Stretch Lite, run:

wget -O - https://raw.githubusercontent.com/sabjorn/hueComposer/master/scripts/install.sh | bash

This git should be put int:

/home/pi/

This will ensure that everything operates properly (hopefully).

Logs are stored in /var/log and over a long period of time this will cause a lot of writes to the SD card (which will damage it). To prevent writes to disk via logs, change the /var/log dir into a tmpfs.

Note: This will cause the logs to NOT persist between reboots. During development, it would likely be best to skip this step.

Run:

sudo vim /etc/fstab

and add:

tmpfs /var/log tmpfs defaults,noatime,nosuid,mode=0755,size=100m 0 0

Then reload by running:

sudo mount -a

NOTE: This section is only needed for development since the files will be stored directly on the PI when deployed.

A FAT32 formatted USB stick is used. The images are stored on the top level. FSTAB is used to automount the USB stick on boot. This way the Pi can be restarted and have different images loaded onto the stick for quick prototyping.

First, a directory must be made to mount to USB stick:

mkdir /home/pi/imgs

Next, FSTAB must be edited to automatically mount the USB stick on reboot. Only one USB stick will be used at a time and, since we want to be able to swap in any stick, the UUID will not be used for mounting--allowing any FAT32 formatted USB device to be mounted on startup:

edit /etc/fstab

sudo vim /etc/fstab

adding

/dev/sda1       /home/pi/imgs   vfat    nofail,uid=pi,gid=pi,rw    0       0

Copy the hueComposer.service into the correct spot

sudo cp ./systemd/hueComposer.service /etc/systemd/system

then enable it

sudo systemctl daemon-reload
sudo systemctl enable hueComposer

This will make the hueComposer app run on boot.

OR

service can be added with direct link:

sudo systemctl enable [absolute path]/hueComposer/systemd/hueComposer.service

• Phue
• numpy
• matplotlib
• PILLOW

Need some way to check which lights are actually available (which lights are plugged in and active)

Filenames for images can contain metadata (rate of play and transition time)

• The IP address of the Hue should be locked on the router side.
