For starters, first follow the installation instructions for https://github.com/uozuAho/pilights

Several files need to be modified

File name flask-app.py

1. Add #!/usr/bin/env python
2. Set the number of LEDS that you will be using. The default is set to "NUM_LEDS = 8".

For the Adafruit NeoPixel ring, e.g. https://www.adafruit.com/product/2853, set NUM_LEDS = 12 for a single ring OR 24 for 2 rings in series

File name neopixels.py

Under "class NeoPixels:":

CHANGE

def init(self, num_leds, output_pin=18, led_freq_hz=800000, dma=5, invert=False, brightness=255): self.pixels = Adafruit_NeoPixel(num_leds, output_pin, led_freq_hz, dma, invert, brightness) self.pixels.begin()

TO

def init(self, num_leds, output_pin=18, led_freq_hz=800000, dma=5, invert=False, brightness=255, channel=0, strip=ws.SK6812W_STRIP): self.pixels = Adafruit_NeoPixel(num_leds, output_pin, led_freq_hz, dma, invert, brightness, channel, strip) self.pixels.begin()

ALso change the relevant parts under class NeoPixelsMock: to include channel and strip

This is to specify the correct setting for Adafruit #2853 which uses the RGBW pixels

File name index.html* Replace with new index.html in this directory

To make a system process

To autostart on boot:

1. Create a configuration file for neopixels.service:

• sudo nano /lib/systemd/system/neopixels.service

2. Enter the following information into the file:

[Unit]

• Description=NEOPIXEL WEB APP
• After=multi-user.target

[Service]

• Type=idle
• ExecStart=/usr/bin/env python /home/pi/pilights/flask-app.py <--- Make sure the directory is correct.

[Install]

• WantedBy=multi-user.target

3. Save and exit the editor.

4. Set permissions by:

• sudo chmod 644 /lib/systemd/system/neopixels.service

5. Configure the service

• sudo systemctl daemon-reload
• sudo systemctl enable neopixels.service

6. Reboot

• sudo reboot

7. Check the status of the running service

• sudo systemctl status neopixels.service
