🌡️ Thermostat UI - Quick Reference

✅ Implementation Complete

Features Implemented

Feature	Status	Details
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
Touch-Friendly	✅	44px minimum button height
Responsive Grid	✅	Adapts to screen size
Event Logging	✅	All actions logged

🎯 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

# 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

# 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

# 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

🔍 Troubleshooting

UI not updating?

# Check SSE connection
curl -N http://localhost:8001/realtime

# Check Redis publishes
tail -f /tmp/abstraction.log | grep "Redis PUBLISH"

Buttons not working?

# Check browser console (F12)
# Check API logs
tail -f /tmp/api.log

Temperature not drifting?

# Check simulator
tail -f /tmp/simulator.log | grep drift
