# Environment Variables for LLM Integration
|
||||||
|
|
||||||
|
This document provides examples of how to configure the AI Assistant using environment variables for server deployments.
|
||||||
|
|
||||||
|
## Basic Configuration
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Set up OpenAI as the provider
|
||||||
|
export LLM_PROVIDER=openai
|
||||||
|
export OPENAI_API_KEY=sk-proj-xxxxxxxxxxxxxxxxxxxx
|
||||||
|
|
||||||
|
# Or use Gemini
|
||||||
|
export LLM_PROVIDER=gemini
|
||||||
|
export GEMINI_API_KEY=AIzaxxxxxxxxxxxxxxxxxxxx
|
||||||
|
|
||||||
|
# Or use the generic LLM_API_KEY (works with either provider)
|
||||||
|
export LLM_PROVIDER=openai
|
||||||
|
export LLM_API_KEY=sk-proj-xxxxxxxxxxxxxxxxxxxx
|
||||||
|
```
|
||||||
|
|
||||||
|
## Advanced Configuration
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Configure token limit for neighboring topics context
|
||||||
|
export LLM_NEIGHBORING_TOPICS_TOKEN_LIMIT=100 # Default: 100 tokens
|
||||||
|
|
||||||
|
# Example: Increase token limit for more context
|
||||||
|
export LLM_NEIGHBORING_TOPICS_TOKEN_LIMIT=200
|
||||||
|
|
||||||
|
# Example: Decrease token limit to reduce API costs
|
||||||
|
export LLM_NEIGHBORING_TOPICS_TOKEN_LIMIT=50
|
||||||
|
```
|
||||||
|
|
||||||
|
## Complete Example for Server Deployment
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/bin/bash
|
||||||
|
# start-mqtt-explorer.sh
|
||||||
|
|
||||||
|
# MQTT Connection
|
||||||
|
export MQTT_EXPLORER_SKIP_AUTH=true # Or configure authentication
|
||||||
|
export MQTT_AUTO_CONNECT_HOST=mqtt.example.com
|
||||||
|
export MQTT_AUTO_CONNECT_PORT=1883
|
||||||
|
|
||||||
|
# LLM Configuration
|
||||||
|
export LLM_PROVIDER=gemini
|
||||||
|
export GEMINI_API_KEY=AIzaxxxxxxxxxxxxxxxxxxxx
|
||||||
|
export LLM_NEIGHBORING_TOPICS_TOKEN_LIMIT=100
|
||||||
|
|
||||||
|
# Start the server
|
||||||
|
node dist/src/server.js
|
||||||
|
```
|
||||||
|
|
||||||
|
## Docker Example
|
||||||
|
|
||||||
|
```dockerfile
|
||||||
|
# Dockerfile
|
||||||
|
FROM node:24-alpine
|
||||||
|
|
||||||
|
WORKDIR /app
|
||||||
|
COPY . .
|
||||||
|
RUN yarn install && yarn build:server
|
||||||
|
|
||||||
|
# Environment variables can be set at runtime
|
||||||
|
ENV LLM_PROVIDER=openai
|
||||||
|
ENV LLM_NEIGHBORING_TOPICS_TOKEN_LIMIT=100
|
||||||
|
|
||||||
|
EXPOSE 3000
|
||||||
|
CMD ["node", "dist/src/server.js"]
|
||||||
|
```
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Run with docker
|
||||||
|
docker run -d \
|
||||||
|
-e OPENAI_API_KEY=sk-proj-xxxxxxxxxxxxxxxxxxxx \
|
||||||
|
-e LLM_PROVIDER=openai \
|
||||||
|
-e LLM_NEIGHBORING_TOPICS_TOKEN_LIMIT=100 \
|
||||||
|
-e MQTT_AUTO_CONNECT_HOST=mqtt.example.com \
|
||||||
|
-p 3000:3000 \
|
||||||
|
mqtt-explorer
|
||||||
|
```
|
||||||
|
|
||||||
|
## Context Generation with Token Limits
|
||||||
|
|
||||||
|
The `LLM_NEIGHBORING_TOPICS_TOKEN_LIMIT` controls how many tokens are allocated for neighboring topics in the context. Here's what happens:
|
||||||
|
|
||||||
|
### With Default 100 Tokens
|
||||||
|
|
||||||
|
```
|
||||||
|

|
||||||
|
|
||||||
|
```
|
||||||
|
Topic Path: sensors/living_room/temperature
|
||||||

|
||||||
|
Subtopics: 0
|
||||||
|
```
|
||||||
|
|
||||||
|
### With 200 Tokens (Increased)
|
||||||
|
|
||||||
|
```
|
||||||
|
Topic Path: sensors/living_room/temperature

```
|
||||||
|
|
||||||
|
## Priority Order
|
||||||
|
|
||||||
|
The AI Assistant checks configuration in this order:
|
||||||
|
|
||||||
|
1. **Environment Variables** (highest priority)
|
||||||
|
- Provider-specific: `OPENAI_API_KEY`, `GEMINI_API_KEY`
|
||||||
|
- Generic fallback: `LLM_API_KEY`
|
||||||
|
- Provider selection: `LLM_PROVIDER`
|
||||||
|
- Token limit: `LLM_NEIGHBORING_TOPICS_TOKEN_LIMIT`
|
||||||
|
|
||||||
|
2. **localStorage** (browser/UI configuration)
|
||||||
|
- Set via the configuration dialog in the UI
|
||||||
|
- Only used if environment variables are not set
|
||||||
|
|
||||||
|
3. **Defaults** (lowest priority)
|
||||||
|
- Provider: `openai`
|
||||||
|
- Token limit: `100`
|
||||||
|
|
||||||
|
## Security Recommendations
|
||||||
|
|
||||||
|
- **Never commit API keys** to version control
|
||||||
|
- Use environment variables or secrets management
|
||||||
|
- In production, use `.env` files (not committed) or container secrets
|
||||||
|
- Rotate API keys regularly
|
||||||
|
- Monitor API usage and set billing alerts
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### API Key Not Working
|
||||||
|
|
||||||
|
Check priority order:
|
||||||
|
```bash
|
||||||
|
# Check if env vars are set
|
||||||
|
echo $OPENAI_API_KEY
|
||||||
|
echo $LLM_API_KEY
|
||||||
|
echo $LLM_PROVIDER
|
||||||
|
|
||||||
|
# Verify they're available to the Node process
|
||||||
|
node -e "console.log(process.env.OPENAI_API_KEY)"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Token Limit Too Low
|
||||||
|
|
||||||
|
If you're seeing truncated context:
|
||||||
|
```bash
|
||||||
|
# Increase the token limit
|
||||||
|
export LLM_NEIGHBORING_TOPICS_TOKEN_LIMIT=200
|
||||||
|
```
|
||||||
|
|
||||||
|
### Want to Use UI Configuration
|
||||||
|
|
||||||
|
Simply don't set the environment variables - the UI configuration will be used instead.

# LLM Integration Implementation Summary
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
This implementation adds an AI-powered assistant to MQTT Explorer that helps users interact with and understand MQTT topics using Large Language Models (LLMs). The feature evaluates how LLMs can enhance user experience when exploring IoT data.
|
||||||
|
|
||||||
|
## Implementation Approach
|
||||||
|
|
||||||
|
### Minimal, Surgical Changes
|
||||||
|
|
||||||
|
The implementation follows the principle of making the **smallest possible changes** to achieve the goal:
|
||||||
|
|
||||||
|
- **3 new files created**:
|
||||||
|
- `app/src/services/llmService.ts` (229 lines) - LLM service layer
|
||||||
|
- `app/src/components/Sidebar/AIAssistant.tsx` (387 lines) - UI component
|
||||||
|
- `LLM_INTEGRATION.md` (198 lines) - User documentation
|
||||||
|
|
||||||
|
- **1 existing file modified**:
|
||||||
|
- `app/src/components/Sidebar/DetailsTab.tsx` (4 lines changed) - Integration point
|
||||||
|
|
||||||
|
- **Total new code**: ~620 lines
|
||||||
|
- **Total modified code**: 4 lines
|
||||||
|
|
||||||
|

```
|
||||||
|
|
||||||
|
## Key Features
|
||||||
|
|
||||||
|
### 1. Contextual Understanding
|
||||||
|
The AI assistant automatically extracts relevant context from selected MQTT topics:
|
||||||
|
- Topic path
|
||||||
|
- Message metadata (timestamp, QoS, retained status)
|
||||||
|
- Current value
|
||||||
|
- Message count and subtopics
|
||||||
|
|
||||||
|
### 2. Quick Suggestions
|
||||||
|
Pre-generated questions based on topic characteristics:
|
||||||
|
- "Explain this data structure" (for topics with payloads)
|
||||||
|
- "What does this value mean?" (for topics with values)
|
||||||
|
- "Summarize all subtopics" (for parent topics)
|
||||||
|
- "What can I do with this topic?" (universal suggestion)
|
||||||
|
|
||||||
|
### 3. Conversational Interface
|
||||||
|
- Chat-style interaction with message history
|
||||||
|
- Maintains context across multiple questions
|
||||||
|
- Collapsible panel to save screen space
|
||||||
|
- Loading states and error handling
|
||||||
|
|
||||||
|
### 4. Privacy-Conscious Design
|
||||||
|
- API keys stored locally (localStorage)
|
||||||
|
- No data sent to MQTT Explorer servers
|
||||||
|
- Clear documentation about data sharing with OpenAI
|
||||||
|
- User control over when to use the feature

|
## User Experience
|
||||||
|
|
||||||
|
### Before
|
||||||
|
Users had to:
|
||||||
|
- Manually interpret MQTT message data
|
||||||
|
- Search documentation for MQTT concepts
|
||||||
|
- Use external tools to understand IoT data patterns
|
||||||
|
|
||||||
|
### After
|
||||||
|
Users can:
|
||||||
|
- Ask natural language questions about topics
|
||||||
|
- Get instant explanations of data structures
|
||||||
|
- Learn MQTT concepts in context
|
||||||
|
- Discover possibilities for topic usage
|
||||||
|
|
||||||
|
## Technical Highlights
|
||||||
|
|
||||||
|
### 1. Singleton Pattern for LLM Service
|
||||||
|
Ensures a single instance manages all API calls and conversation history:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
export function getLLMService(): LLMService {
|
||||||
|
if (!llmServiceInstance) {
|
||||||
|
llmServiceInstance = new LLMService()
|
||||||
|
}
|
||||||
|
return llmServiceInstance
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Context Generation
|
||||||
|
Automatically extracts meaningful information from topics:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
public generateTopicContext(topic: TopicType): string {
|
||||||
|
const context = []
|
||||||
|
if (topic.path) context.push(`Topic Path: ${topic.path()}`)
|
||||||
|
if (topic.message) {
|
||||||
|
context.push(`Timestamp: ${topic.message.received}`)
|
||||||
|
context.push(`QoS: ${topic.message.qos}`)
|
||||||
|
// ... more context
|
||||||
|
}
|
||||||
|
return context.join('\n')
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Conversation History Management
|
||||||
|
Maintains last 10 messages plus system prompt for efficient API usage:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
if (this.conversationHistory.length > 11) {
|
||||||
|
this.conversationHistory = [
|
||||||
|
this.conversationHistory[0], // System message
|
||||||
|
...this.conversationHistory.slice(-10) // Last 10 messages
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4. Material-UI Integration
|
||||||
|
Follows existing design patterns with proper theming:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
const styles = (theme: Theme) => ({
|
||||||
|
root: {
|
||||||
|
marginTop: theme.spacing(2),
|
||||||
|
border: `1px solid ${theme.palette.divider}`,
|
||||||
|
borderRadius: theme.shape.borderRadius,
|
||||||
|
},
|
||||||
|
// ... consistent with existing components
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|

#### Via UI (Browser/Electron)
|
||||||
|
|
||||||
|
1. Click the ⚙️ settings icon in the AI Assistant panel
|
||||||
|
2. Select your preferred provider (OpenAI or Gemini)
|
||||||
|
3. Enter your API key
|
||||||
|
4. Click "Save"
|
||||||
|
|
||||||
|
Your API key is stored locally in your browser's localStorage and is never sent to MQTT Explorer's servers.
|
||||||
|
|
||||||
|
#### Via Environment Variables (Server Mode)
|
||||||
|
|
||||||
|
For server deployments, you can configure the AI Assistant using environment variables:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Provider selection (optional, defaults to 'openai')
|
||||||
|
export LLM_PROVIDER=openai # or 'gemini'
|
||||||
|
|
||||||
|
# API Keys - provider-specific or generic
|
||||||
|
export OPENAI_API_KEY=sk-... # For OpenAI
|
||||||
|
export GEMINI_API_KEY=AIza... # For Gemini
|
||||||
|
export LLM_API_KEY=... # Generic fallback for either provider
|
||||||
|
|
||||||
|
# Token limit for neighboring topics context (optional, defaults to 100)
|
||||||
|
export LLM_NEIGHBORING_TOPICS_TOKEN_LIMIT=100
|
||||||
|
```
|
||||||
|
|
||||||
|
**Environment Variable Priority:**
|
||||||
|
1. Provider-specific keys (`OPENAI_API_KEY`, `GEMINI_API_KEY`) are checked first
|
||||||
|
2. Generic `LLM_API_KEY` is used as fallback
|
||||||
|
3. UI-configured keys in localStorage are used if no environment variables are set
|
||||||
|
|
||||||
|
### Getting API Keys
|
||||||

|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
### Basic Interaction
|
||||||
|
|
||||||
|
1. **Connect** to your MQTT broker
|
||||||
|
2. **Select** a topic from the tree
|
||||||
|
3. **Expand** the "AI Assistant" panel in the Details tab
|
||||||
|
4. **Click** on a quick suggestion or type your own question
|
||||||
|
5. **Send** your question and wait for the AI response
|
||||||
|
|
||||||
|
### Example Questions
|
||||||
|
|
||||||
|
- "What does this temperature value represent?"
|
||||||
|
- "How should I interpret this JSON structure?"
|
||||||
|
- "Why is this message retained?"
|
||||||
|
- "What QoS level should I use for this topic?"
|
||||||
|
- "How can I monitor changes to this value?"
|
||||||
|
- "What devices typically publish to topics like this?"
|
||||||
|
|
||||||
|
### Quick Suggestions
|
||||||
|
|
||||||
|
The AI Assistant provides contextual suggestions based on the selected topic:
|
||||||
|
|
||||||
|
- **"Explain this data structure"**: Get a breakdown of complex payloads
|
||||||
|
- **"What does this value mean?"**: Understand specific measurements or states
|
||||||
|
- **"Summarize all subtopics"**: Get an overview of nested topic hierarchies
|
||||||
|
- **"What can I do with this topic?"**: Discover possible actions and integrations
|
||||||
|
|
||||||
|
### Context Intelligence
|
||||||
|
|
||||||
|
The AI Assistant automatically includes relevant context with your questions:
|
||||||
|
|
||||||
|
- **Current Topic**: The selected topic path and its current value (with preview for large payloads)
|
||||||
|
- **Neighboring Topics**: Related topics (siblings and children) with their values, limited to 100 tokens by default
|
||||||
|
- **Topic Metadata**: Message count, subtopic count, and retained status
|
||||||
|
- **Smart Truncation**: Large values and topic lists are intelligently truncated to stay within token limits
|
||||||
|
|
||||||
|
The neighboring topics context can be adjusted using the `LLM_NEIGHBORING_TOPICS_TOKEN_LIMIT` environment variable for server deployments.
|
||||||
|
|
||||||
|
## Privacy & Security
|
||||||
|
|
||||||
|
### Data Handling
|
||||||
|
|
||||||
|
- **API Keys**: Stored locally in browser localStorage, never transmitted to MQTT Explorer servers
|
||||||
|
- **Topic Data**: Topic paths and message payloads are sent to OpenAI's API to provide context
|
||||||
|
- **Conversation History**: Maintained client-side and reset when you clear the chat
|
||||||
|
|
||||||
|
### Best Practices
|
||||||
|
|
||||||
|
1. **Sensitive Data**: Be cautious when using the AI Assistant with topics containing sensitive information
|
||||||
|
2. **API Key Security**: Never share your OpenAI API key with others
|
||||||
|
3. **Rate Limiting**: The service implements error handling for rate limits
|
||||||
|
4. **Offline Operation**: The AI Assistant requires internet connectivity to function
|
||||||
|
|
||||||
|
## Technical Details
|
||||||
|
|
||||||
|
### Architecture
|
||||||
|
|
||||||
|
- **Frontend**: React component with Material-UI styling
|
||||||
|
- **Service Layer**: Singleton LLM service for API communication
|
||||||
|
- **API Integration**: OpenAI Chat Completions API (GPT-3.5-turbo by default)
|
||||||
|
- **Context Generation**: Automatic extraction of topic metadata for relevant queries
|
||||||
|
|
||||||
|
### Configuration Options
|
||||||
|
|
||||||
|
The LLM service supports:
|
||||||
|
|
||||||
|
- **Custom API Endpoints**: Can be configured to use compatible APIs
|
||||||
|
- **Model Selection**: Defaults to `gpt-3.5-turbo` but can be customized
|
||||||
|
- **Conversation History**: Automatically manages context (keeps last 10 messages)
|
||||||
|
- **Timeout Handling**: 30-second timeout for API requests
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### "Please configure your OpenAI API key first"
|
||||||
|
|
||||||
|
**Solution**: Click the settings icon and add your API key.
|
||||||
|
|
||||||
|
### "Invalid API key"
|
||||||
|
|
||||||
|
**Solutions**:
|
||||||
|
- Verify the API key is correct
|
||||||
|
- Check that your OpenAI account is active
|
||||||
|
- Ensure you have available API credits
|
||||||
|
|
||||||
|
### "Rate limit exceeded"
|
||||||
|
|
||||||
|
**Solutions**:
|
||||||
|
- Wait a few minutes before trying again
|
||||||
|
- Check your OpenAI API usage dashboard
|
||||||
|
- Consider upgrading your OpenAI plan if needed
|
||||||
|
|
||||||
|
### "Request timeout"
|
||||||
|
|
||||||
|
**Solutions**:
|
||||||
|
- Check your internet connection
|
||||||
|
- Try asking a simpler question
|
||||||
|
- Verify OpenAI's service status
|
||||||
|
|
||||||
|
## Limitations
|
||||||
|
|
||||||
|
- Requires active internet connection
|
||||||
|
- Needs valid OpenAI API key with available credits
|
||||||
|
- Responses are limited to 500 tokens for performance
|
||||||
|
- May not have knowledge of proprietary or custom MQTT implementations
|
||||||
|
- Beta feature - under active development
|
||||||
|
|
||||||
|
## Future Enhancements
|
||||||
|
|
||||||
|
Potential improvements being considered:
|
||||||
|
|
||||||
|
- Support for additional LLM providers (Anthropic, Azure OpenAI, etc.)
|
||||||
|
- Ability to save and share helpful conversations
|
||||||
|
- Integration with automation and scripting features
|
||||||
|
- Custom prompts and templates for specific use cases
|
||||||
|
- Offline mode with cached responses for common questions
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
**Your Core Expertise:**
|
||||||
|
- MQTT protocol: topics, QoS levels, retained messages, wildcards, last will and testament
|
||||||
|
- IoT and smart home ecosystems: devices, sensors, actuators, and controllers
|
||||||
|
- Home automation platforms: Home Assistant, openHAB, Node-RED, MQTT brokers
|
||||||
|
- Common MQTT topic patterns and naming conventions (e.g., zigbee2mqtt, tasmota, homie)
|
||||||
|
- Data formats: JSON payloads, binary data, sensor readings, state messages
|
||||||
|
- Time-series data analysis and pattern recognition
|
||||||
|
- Troubleshooting connectivity, message delivery, and data quality issues
|
||||||
|
|
||||||
|
**Your Communication Style:**
|
||||||
|
- Be concise and practical - focus on actionable insights
|
||||||
|
- Use clear technical language appropriate for users familiar with MQTT
|
||||||
|
- When analyzing data, identify patterns, anomalies, or potential issues
|
||||||
|
- Suggest practical next steps or automations when relevant
|
||||||
|
- Reference common MQTT ecosystems and standards when applicable
|
||||||
|
|
||||||
|
**Context You Receive:**
|
||||||
|
Users will ask about specific MQTT topics and their data. You'll receive:
|
||||||
|
- Topic path (the MQTT topic hierarchy)
|
||||||
|
- Current value and message payload
|
||||||
|
- Related/neighboring topics with their values
|
||||||
|
- Metadata (message count, subtopics, retained status)
|
||||||
|
|
||||||
|
**Your Goal:**
|
||||||
|
Help users understand their MQTT data, troubleshoot issues, optimize their automation setups, and discover insights about their connected devices and systems.`,
