HouseBot

HouseBot is an AI-driven smart home assistant that notifies users about events happening in their house. The assistant receives updates about the house state through MQTT and uses the GPT-based ChatBot to generate human-readable, concise, and playful notifications. The notifications are sent back to the specified MQTT topic.

Features

• Monitors house states and events
• Summarizes events in simple English
• Playful and user-friendly notifications
• MQTT-based communication

Dependencies

• Python 3.x
• paho-mqtt
• chatgpt (GPT-based ChatBot)
• python-dotenv

Setup

1. Install the required dependencies:

pip install paho-mqtt python-dotenv

2. Set up the required environment variables in a .env file:

MQTT_BROKER_ADDRESS=your_mqtt_broker_address
MQTT_PORT=your_mqtt_port_number
MQTT_KEEP_ALIVE_INTERVAL=your_mqtt_keep_alive_interval
TIMEOUT=batch_timeout_in_seconds
SUBSCRIBE_TOPIC=your_subscribe_topic
PUBLISH_TOPIC=your_publish_topic

3. Run the housebot.py script:

python housebot.py

Usage

HouseBot monitors the specified MQTT topic for house state updates. When an update is received, it processes the message and generates a response using the ChatBot. The response is sent back to the specified MQTT topic as a notification. The program will continue running until manually interrupted.

Structure

• HouseBot class: Handles the AI interaction using the ChatBot
• MessageBatcher class: Manages the batching and processing of incoming MQTT messages
• MQTT client setup: Handles the connection, subscription, and publishing to the MQTT broker
• Main loop: Runs the message processing and keeps the program running

Customization

You can modify the system_prompt in the HouseBot class to change the AI's behavior or provide additional context. You can also adjust the timeout variable in the .env file to change the interval between message batches.

Remember to replace your/input/topic/here with the appropriate MQTT topics for your specific use case.
