| Temperature Display | ✅ | Ist (current) & Soll (target) in °C |
| Mode Display | ✅ | Shows OFF/HEAT/AUTO |
| +0.5 Button | ✅ | Increases target temperature |
| -0.5 Button | ✅ | Decreases target temperature |
| Mode Buttons | ✅ | OFF, HEAT, AUTO switches |
| Real-time Updates | ✅ | SSE-based live updates |
| Temperature Drift | ✅ | ±0.2°C every 5 seconds |

---

## 🎯 Acceptance Criteria Status

- ✅ Click +0.5 → increases target & sends POST
- ✅ Click -0.5 → decreases target & sends POST
- ✅ Mode buttons send POST requests
- ✅ No JavaScript console errors
- ✅ SSE updates current/target/mode without reload

## 🚀 Quick Start

### 1. Start All Services
```bash
# Abstraction Layer
poetry run python -m apps.abstraction.main > /tmp/abstraction.log 2>&1 &

# API Server
poetry run uvicorn apps.api.main:app --host 0.0.0.0 --port 8001 > /tmp/api.log 2>&1 &

# UI Server
poetry run uvicorn apps.ui.main:app --host 0.0.0.0 --port 8002 > /tmp/ui.log 2>&1 &

# Device Simulator
poetry run python tools/device_simulator.py > /tmp/simulator.log 2>&1 &
```

### 2. Access UI
```
http://localhost:8002
```

### 3. Monitor Logs
```bash
# Real-time log monitoring
tail -f /tmp/abstraction.log   # MQTT & Redis activity
tail -f /tmp/simulator.log     # Device simulation
tail -f /tmp/api.log           # API requests
```

---

## 🧪 Testing

### Quick Test
```bash
# Adjust temperature
curl -X POST http://localhost:8001/devices/test_thermo_1/set \
  -H "Content-Type: application/json" \
  -d '{"type":"thermostat","payload":{"mode":"heat","target":22.5}}'

# Check simulator response
tail -3 /tmp/simulator.log
```

### Full Test Suite
```bash
/tmp/test_thermostat_ui.sh
```

---

## 📊 Current State

**Device ID:** `test_thermo_1`

**Live State:**
- Mode: AUTO
- Target: 23.0°C
- Current: ~23.1°C (drifting)
- Battery: 90%

## 🔧 API Reference

### Set Thermostat
```http
POST /devices/{device_id}/set
Content-Type: application/json

{
  "type": "thermostat",
  "payload": {
    "mode": "heat",      // Required: "off" | "heat" | "auto"
    "target": 22.5       // Required: 5.0 - 30.0
  }
}
```

### Response
```json
{
  "message": "Command sent to test_thermo_1"
}
```

## 🎨 UI Components

### Thermostat Card Structure
```
┌─────────────────────────────────────┐
│ 🌡️ Living Room Thermostat          │
│ test_thermo_1                       │
├─────────────────────────────────────┤
│  Ist: 23.1°C    Soll: 23.0°C       │
├─────────────────────────────────────┤
│         Modus: AUTO                 │
├─────────────────────────────────────┤
│    [ -0.5 ]      [ +0.5 ]          │
├─────────────────────────────────────┤
│  [ OFF ]  [ HEAT* ]  [ AUTO ]      │
└─────────────────────────────────────┘
```

### JavaScript Functions
```javascript
adjustTarget(deviceId, delta)  // ±0.5°C
setMode(deviceId, mode)        // "off"|"heat"|"auto"
updateThermostatUI(...)        // Auto-called by SSE
```

## 📱 Responsive Breakpoints

| Screen Width | Columns | Card Width |
|--------------|---------|------------|
| < 600px      | 1       | 100%       |
| 600-900px    | 2       | ~300px     |
| 900-1200px   | 3       | ~300px     |
| > 1200px     | 4       | ~300px     |

## 🔍 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
```
