Raspberry Pico to Home Assistant by MQTT

Home assistant MQTT discovery to GPIO as switch entities.

main.py in this project acts as a bridge between Home Assistant and your Raspberry Pico's GPIO pins. It connects to an MQTT broker, listens for Home Assistant's discovery messages, and configures GPIO pins as switch entities based on these messages. It also listens for commands from Home Assistant to control the state of these GPIO pins.

Installation

Update secrets.py with your WiFi and MQTT broker details.

Upload the project to your Raspberry Pico.
