Script and Workflow to show Particulate Matter/Air-Quality (Feinstaub) values on a Divoom Pixoo 64 display. https://divoom.com/products/pixoo-64. The sensor data is pulled from your or nearby station from the awesome project https://sensor.community/.

setup the great project https://github.com/4ch1m/pixoo-rest to interact via REST API with Pixoo64

-modify .env setup the IP to pixoo (according the introduction) and setup port for REST

-recommended to create launcher.sh to start REST API on reboot cd /home/pi/scripts/pixoo-rest/pixoo-rest/

nano launcher.sh

#!/bin/sh
# launcher.sh
# navigate to home directory, then to this directory, then execute python scrip$

cd /
cd home/pi/scripts/pixoo-rest/pixoo-rest
/usr/local/bin/python3 app.py
cd /

CTRL + X Y

run launcher.sh to start REST API. By opening the brwoser with respective IP and Port, the swager UI should be available sh launcher.sh

• copy folder pm-display-logic including python file and TTF (font for pixoo) to your linux env.
• install all python dependencies. Tested with python 3.7, but should work also with newer versions.
• customize the configuration directly in python file:

sensor_station = '12345' choose your sensor station ID on https://maps.sensor.community/#9/48.8676/9.4095

rest_host = 'http://192.168.2.100:5001' select the IP and PORT where your REST API runs.

path_to_font_file = '/home/pi/scripts/pm-display/PICO-8_mod.ttf' pixoo64 has limited pixel density, therefore a special font is used. make sure you insert absolut path to the *.ttf file

run the pyton script to test and verify if everthing is setup properly

cd /home/pi/scripts/pm-display/ (location of python file)

python main.py or python3 main.py

trigger the main.py periodically. Default is 1 minute, setup via crontab.

crontab -e

optional: if REST API runs on same machine, with a restart the REST starts:

@reboot sh /home/pi/scripts/pixoo-rest/pixoo-rest/launcher.sh >/home/pi/scripts/pixoo-rest/pixoo-rest/logslauncher/cronlog 2>&1

add this to the end of crontab file:

* * * * * sleep 0; /usr/local/bin/python3 /home/pi/scripts/pm-display/main.py >> /home/pi/scripts/pm-display/logmain.log 2>&1
