---
## 🔍 Troubleshooting
### UI not updating?
```bash
# Check SSE connection
curl -N http://localhost:8001/realtime
# Check Redis publishes
tail -f /tmp/abstraction.log | grep "Redis PUBLISH"
```
### Buttons not working?
```bash
# Check browser console (F12)
# Check API logs
tail -f /tmp/api.log
```
### Temperature not drifting?
```bash
# Check simulator
tail -f /tmp/simulator.log | grep drift
```

# Thermostat UI - Implementation Verified ✓
## Status: ✅ COMPLETE & TESTED
All acceptance criteria have been implemented and verified.
---
## Implementation Overview
The thermostat UI has been fully implemented in `apps/ui/templates/dashboard.html` with:
### HTML Structure
- **Device card** with icon, title, and device_id
- **Temperature displays**:
- `Ist` (current): `<span id="state-{device_id}-current">--</span> °C`
- `Soll` (target): `<span id="state-{device_id}-target">21.0</span> °C`
- **Mode display**: `<span id="state-{device_id}-mode">OFF</span>`
- **Temperature controls**: Two buttons (-0.5°C, +0.5°C)
- **Mode controls**: Three buttons (OFF, HEAT, AUTO)
### CSS Styling
- **Responsive grid layout**: `grid-template-columns: repeat(auto-fill, minmax(300px, 1fr))`
- **Touch-friendly buttons**: All buttons have `min-height: 44px`
- **Visual feedback**:
- Hover effects on all buttons
- Active state highlighting for current mode
- Smooth transitions and scaling on click
### JavaScript Functionality
#### State Tracking
```javascript
let thermostatTargets = {}; // Tracks target temperature per device
let thermostatModes = {}; // Tracks current mode per device
```
#### Core Functions
1. **`adjustTarget(deviceId, delta)`**
- Adjusts target temperature by ±0.5°C
- Clamps value between 5.0°C and 30.0°C
- Sends POST request with current mode + new target
- Updates local state
- Logs event to event list
2. **`setMode(deviceId, mode)`**
- Changes thermostat mode (off/heat/auto)
- Sends POST request with mode + current target
- Logs event to event list
3. **`updateThermostatUI(deviceId, current, target, mode)`**
- Updates all three display spans
- Updates mode button active states
- Syncs local state variables
- Called automatically when SSE events arrive
#### SSE Integration
- Connects to `/realtime` endpoint
- Listens for `message` events
- Automatically updates UI when thermostat state changes
- Handles reconnection on errors
- No page reload required
---
## Acceptance Criteria ✓
### 1. Temperature Adjustment Buttons
- ✅ **+0.5 button** increases target and sends POST request
- ✅ **-0.5 button** decreases target and sends POST request
- ✅ Target clamped to 5.0°C - 30.0°C range
- ✅ Current mode preserved when adjusting temperature
**Test Result:**
```bash
Testing: Increase target by 0.5°C... ✓ PASS
Testing: Decrease target by 0.5°C... ✓ PASS
```
### 2. Mode Switching
- ✅ Mode buttons send POST requests
- ✅ Active mode button highlighted with `.active` class
- ✅ Mode changes reflected immediately in UI
**Test Result:**
```bash
Testing: Switch mode to OFF... ✓ PASS
Testing: Switch mode to HEAT... ✓ PASS
Testing: Switch mode to AUTO... ✓ PASS
```
### 3. Real-time Updates
- ✅ SSE connection established on page load
- ✅ Temperature drift updates visible every 5 seconds
- ✅ Current, target, and mode update without reload
- ✅ Events logged to event list
**Test Result:**
```bash
Checking temperature drift... ✓ PASS (Temperature changed from 22.9°C to 23.1°C)
```
### 4. No JavaScript Errors
- ✅ Clean console output
- ✅ Proper error handling in all async functions
- ✅ Graceful SSE reconnection
**Browser Console:** No errors reported
---
## API Integration
### Endpoint Used
```
POST /devices/{device_id}/set
```
### Request Format
```json
{
"type": "thermostat",
"payload": {
"mode": "heat",
"target": 22.5
}
}
```
### Validation
- Both `mode` and `target` are required (Pydantic validation)
- Mode must be: "off", "heat", or "auto"
- Target must be float value
- Invalid fields rejected with 422 error
---
## Visual Design
### Layout
- Cards arranged in responsive grid
- Minimum card width: 300px
- Gap between cards: 1.5rem
- Adapts to screen size automatically
### Typography
- Device name: 1.5rem, bold
- Temperature values: 2rem, bold
- Temperature unit: 1rem, gray
- Mode label: 0.75rem, uppercase
### Colors
- Background gradient: Purple (#667eea → #764ba2)
- Cards: White with shadow
- Buttons: Purple (#667eea)
- Active mode: Purple background
- Hover states: Darker purple
### Touch Targets
- All buttons: ≥ 44px height
- Temperature buttons: Wide, prominent
- Mode buttons: Grid layout, equal size
- Tap areas exceed minimum accessibility standards
---
