Python script to send on/off commands via mqtt. Commands are triggered by pull up/down on raspberry pi GPIO + docker build

rpi-gpio-mqtt-on-off-switch

This python script waiting for state change of specified GPIO pin. On change, it will verify the signal and send message via MQTT to specified topic. Multiple containers can run simultaneously with different env variables to setup gpio, topic etc...
