Setup

Raspberry Pi

1. Install requirements:

   pip install paho-mqtt

3. (Optional) Set up cronjob to run daily at 00:00:

   crontab -e

   Add the following line:

   0 0 * * * /usr/bin/python3 /path/to/mqtt-prayer-info/pi/main.py
   

4. Run manually if needed:

   cd pi
   python3 main.py

ESP32/ESP8266

1. Flash MicroPython firmware (download).
2. Edit esp/config.py with Wi-Fi & MQTT settings.
3. Upload:

   cd esp
   mpremote connect /dev/ttyUSB0 cp -r ./ :

4. Reset board — main.py runs automatically.
