+# MAX! (eQ-3) Thermostat Integration
+
+## Overview
+
+This document describes the integration of MAX! (eQ-3) thermostats via Homegear into the home automation system.
+
+## Protocol Characteristics
+
+MAX! thermostats use a **simple integer-based protocol** (not JSON):
+
+- **SET messages**: Plain integer temperature value (e.g., `22`)
+- **STATE messages**: Plain integer temperature value (e.g., `22`)
+- **Topics**: Homegear MQTT format
+
+### MQTT Topics
+
+**SET Command:**
+```
+homegear/instance1/set/<peerId>/<channel>/SET_TEMPERATURE
+Payload: "22" (plain integer as string)
+```
+
+**STATE Update:**
+```
+homegear/instance1/plain/<peerId>/<channel>/SET_TEMPERATURE
+Payload: "22" (plain integer as string)
+```
+
+## Transformation Layer
+
+The abstraction layer provides automatic transformation between the abstract home protocol and MAX! format.
+
+### Abstract → MAX! (SET)
+
+**Input (Abstract):**
+```json
+{
+  "mode": "heat",
+  "target": 22.5
+}
+```
+
+**Output (MAX!):**
+```
+22
+```
+
+**Transformation Rules:**
+- Extract `target` temperature
+- Convert float → integer (round to nearest)
+- Return as plain string (no JSON)
+- Ignore `mode` field (MAX! always in heating mode)
+
+### MAX! → Abstract (STATE)
+
+**Input (MAX!):**
+```
+22
+```
+
+**Output (Abstract):**
+```json
+{
+  "target": 22.0,
+  "mode": "heat"
+}
+```
+
+**Transformation Rules:**
+- Parse plain string/integer value
+- Convert to float
+- Add default `mode: "heat"` (MAX! always heating)
+- Wrap in abstract payload structure
+
+## Device Configuration
+
+### Example devices.yaml Entry
+
+```yaml
+- device_id: "thermostat_wolfgang"
+  type: "thermostat"
+  cap_version: "thermostat@1.0.0"
+  technology: "max"
+  features:
+    mode: true
+    target: true
+    current: false  # SET_TEMPERATURE doesn't report current temp
+  topics:
+    set: "homegear/instance1/set/39/1/SET_TEMPERATURE"
+    state: "homegear/instance1/plain/39/1/SET_TEMPERATURE"
+  metadata:
+    friendly_name: "Thermostat Wolfgang"
+    location: "Arbeitszimmer Wolfgang"
+    vendor: "eQ-3"
+    model: "MAX! Thermostat"
+    peer_id: "39"
+    channel: "1"
+```
+
+### Configuration Notes
+
+1. **technology**: Must be set to `"max"` to activate MAX! transformations
+2. **topics.set**: Use Homegear's `/set/` path with `/SET_TEMPERATURE` parameter
+3. **topics.state**: Use Homegear's `/plain/` path with `/SET_TEMPERATURE` parameter
+4. **features.current**: Set to `false` - SET_TEMPERATURE topic doesn't provide current temperature
+5. **metadata**: Include `peer_id` and `channel` for reference
+
+## Temperature Rounding
+
+MAX! only supports **integer temperatures**. The system uses standard rounding:
+
+| Abstract Input | MAX! Output |
+|----------------|-------------|
+| 20.4°C         | 20          |
+| 20.5°C         | 20          |
+| 20.6°C         | 21          |
+| 21.5°C         | 22          |
+| 22.5°C         | 22          |
+
+Python's `round()` function uses "banker's rounding" (round half to even).
+
+## Limitations
+
+1. **No current temperature**: SET_TEMPERATURE topic only reports target, not actual temperature
+2. **No mode control**: MAX! thermostats are always in heating mode
+3. **Integer only**: Temperature precision limited to 1°C steps
+4. **No battery status**: Not available via SET_TEMPERATURE topic
+5. **No window detection**: Not available via SET_TEMPERATURE topic
+
+## Testing
+
+Test the transformation functions:
+
+```bash
+poetry run python /tmp/test_max_transform.py
+```
+
+Expected output:
+```
+✅ PASS: Float 22.5 -> Integer string
+✅ PASS: Integer string -> Abstract dict
+✅ PASS: Integer -> Abstract dict
+✅ PASS: Rounding works correctly
+🎉 All MAX! transformation tests passed!
+```
+
+## Implementation Details
+
+### Files Modified
+
+1. **apps/abstraction/transformation.py**
+   - Added `_transform_thermostat_max_to_vendor()` - converts abstract → plain integer
+   - Added `_transform_thermostat_max_to_abstract()` - converts plain integer → abstract
+   - Registered handlers in `TRANSFORM_HANDLERS` registry
+
+2. **apps/abstraction/main.py**
+   - Modified `handle_abstract_set()` to send plain string for MAX! devices (not JSON)
+   - Modified message processing to handle plain text payloads from MAX! STATE topics
+
+### Transformation Functions
+
+```python
+def _transform_thermostat_max_to_vendor(payload: dict[str, Any]) -> str:
+    """Convert {"target": 22.5} → "22" """
+    target_temp = payload.get("target", 21.0)
+    return str(int(round(target_temp)))
+
+def _transform_thermostat_max_to_abstract(payload: str | int | float) -> dict[str, Any]:
+    """Convert "22" → {"target": 22.0, "mode": "heat"} """
+    target_temp = float(payload)
+    return {"target": target_temp, "mode": "heat"}
+```
+
+## Usage Example
+
+### Setting Temperature via API
+
+```bash
+curl -X POST http://localhost:8001/devices/thermostat_wolfgang/set \
+  -H "Content-Type: application/json" \
+  -d '{
+    "type": "thermostat",
+    "payload": {
+      "mode": "heat",
+      "target": 22.5
+    }
+  }'
+```
+
+**Flow:**
+1. API receives abstract payload: `{"mode": "heat", "target": 22.5}`
+2. Abstraction transforms to MAX!: `"22"`
+3. Publishes to: `homegear/instance1/set/39/1/SET_TEMPERATURE` with payload `22`
+
+### Receiving State Updates
+
+**Homegear publishes:**
+```
+Topic: homegear/instance1/plain/39/1/SET_TEMPERATURE
+Payload: 22
+```
+
+**Flow:**
+1. Abstraction receives plain text: `"22"`
+2. Transforms to abstract: `{"target": 22.0, "mode": "heat"}`
+3. Publishes to: `home/thermostat/thermostat_wolfgang/state`
+4. Publishes to Redis: `ui:updates` channel for real-time UI updates
+
+## Future Enhancements
+
+Potential improvements for better MAX! integration:
+
+1. **Current Temperature**: Subscribe to separate Homegear topic for actual temperature
+2. **Battery Status**: Subscribe to LOWBAT or battery level topics
+3. **Valve Position**: Monitor actual valve opening percentage
+4. **Window Detection**: Subscribe to window open detection status
+5. **Mode Control**: Support comfort/eco temperature presets

+# Rule Interface Documentation
+
+## Overview
+
+The rule interface provides a clean abstraction for implementing automation rules. Rules respond to device state changes and can publish commands, persist state, and log diagnostics.
+
+## Core Components
+
+### 1. RuleDescriptor
+
+Configuration data for a rule instance (loaded from `rules.yaml`):
+
+```python
+RuleDescriptor(
+    id="window_setback_wohnzimmer",           # Unique rule ID
+    name="Fensterabsenkung Wohnzimmer",       # Optional display name
+    type="window_setback@1.0",                # Rule type + version
+    targets={                                  # Rule-specific targets
+        "rooms": ["Wohnzimmer"],
+        "contacts": ["kontakt_wohnzimmer_..."],
+        "thermostats": ["thermostat_wohnzimmer"]
+    },
+    params={                                   # Rule-specific parameters
+        "eco_target": 16.0,
+        "open_min_secs": 20
+    }
+)
+```
+
+### 2. RedisState
+
+Async state persistence with automatic reconnection and retry logic:
+
+```python
+# Initialize (done by rule engine)
+redis_state = RedisState("redis://172.23.1.116:6379/8")
+
+# Simple key-value with TTL
+await ctx.redis.set("rules:my_rule:temp", "22.5", ttl_secs=3600)
+value = await ctx.redis.get("rules:my_rule:temp")  # Returns "22.5" or None
+
+# Hash storage (for multiple related values)
+await ctx.redis.hset("rules:my_rule:sensors", "bedroom", "open")
+await ctx.redis.hset("rules:my_rule:sensors", "kitchen", "closed")
+value = await ctx.redis.hget("rules:my_rule:sensors", "bedroom")  # "open"
+
+# TTL management
+await ctx.redis.expire("rules:my_rule:temp", 7200)  # Extend to 2 hours
+
+# JSON helpers (for complex data)
+import json
+data = {"temp": 22.5, "humidity": 45}
+await ctx.redis.set("rules:my_rule:data", ctx.redis._dumps(data))
+stored = await ctx.redis.get("rules:my_rule:data")
+parsed = ctx.redis._loads(stored) if stored else None
+```
+
+**Key Conventions:**
+- Use prefix `rules:{rule_id}:` for all keys
+- Example: `rules:window_setback_wohnzimmer:thermo:device_123:previous`
+- TTL recommended for temporary state (previous temperatures, timers)
+
+**Robustness Features:**
+- Automatic retry with exponential backoff (default: 3 retries)
+- Connection pooling (max 10 connections)
+- Automatic reconnection on Redis restart
+- Health checks every 30 seconds
+- All operations wait and retry, no exceptions on temporary outages
+
+### 3. MQTTClient
+
+Async MQTT client with event normalization and command publishing:
+
+```python
+# Initialize (done by rule engine)
+mqtt_client = MQTTClient(
+    broker="172.16.2.16",
+    port=1883,
+    client_id="rule_engine"
+)
+
+# Subscribe and receive normalized events
+async for event in mqtt_client.connect():
+    # Event structure:
+    # {
+    #     "topic": "home/contact/sensor_1/state",
+    #     "type": "state",
+    #     "cap": "contact",           # Capability (contact, thermostat, etc.)
+    #     "device_id": "sensor_1",
+    #     "payload": {"contact": "open"},
+    #     "ts": "2025-11-11T10:30:45.123456"
+    # }
+    
+    if event['cap'] == 'contact':
+        handle_contact(event)
+    elif event['cap'] == 'thermostat':
+        handle_thermostat(event)
+
+# Publish commands (within async context)
+await mqtt_client.publish_set_thermostat("thermostat_id", 22.5)
+```
+
+**Subscriptions:**
+- `home/contact/+/state` - All contact sensor state changes
+- `home/thermostat/+/state` - All thermostat state changes
+
+**Publishing:**
+- Topic: `home/thermostat/{device_id}/set`
+- Payload: `{"type":"thermostat","payload":{"target":22.5}}`
+- QoS: 1 (at least once delivery)
+
+**Robustness:**
+- Automatic reconnection with exponential backoff
+- Connection logging (connect/disconnect events)
+- Clean session handling
+
+### 4. MQTTPublisher (Legacy)
+
+Simplified wrapper around MQTTClient for backward compatibility:
+
+```python
+# Set thermostat temperature
+await ctx.mqtt.publish_set_thermostat("thermostat_wohnzimmer", 21.5)
+```
+
+### 5. RuleContext
+
+Runtime context provided to rules:
+
+```python
+class RuleContext:
+    logger           # Logger instance
+    mqtt             # MQTTPublisher
+    redis            # RedisState
+    now() -> datetime  # Current timestamp
+```
+
+### 5. Rule Abstract Base Class
+
+All rules extend this:
+
+```python
+class MyRule(Rule):
+    async def on_event(self, evt: dict, desc: RuleDescriptor, ctx: RuleContext) -> None:
+        # Event structure:
+        # {
+        #     "topic": "home/contact/device_id/state",
+        #     "type": "state",
+        #     "cap": "contact",
+        #     "device_id": "kontakt_wohnzimmer",
+        #     "payload": {"contact": "open"},
+        #     "ts": "2025-11-11T10:30:45.123456"
+        # }
+        
+        device_id = evt['device_id']
+        cap = evt['cap']
+        
+        if cap == 'contact':
+            contact_state = evt['payload'].get('contact')
+            # ... implement logic
+```
+
+## Implementing a New Rule
+
+### Step 1: Create Rule Class
+
+```python
+from packages.rule_interface import Rule, RuleDescriptor, RuleContext
+from typing import Any
+
+class MyCustomRule(Rule):
+    """My custom automation rule."""
+    
+    async def on_event(
+        self,
+        evt: dict[str, Any],
+        desc: RuleDescriptor,
+        ctx: RuleContext
+    ) -> None:
+        """Process device state changes."""
+        
+        # 1. Extract event data
+        device_id = evt['device_id']
+        cap = evt['cap']
+        payload = evt['payload']
+        
+        # 2. Filter to relevant devices
+        if device_id not in desc.targets.get('my_devices', []):
+            return
+        
+        # 3. Implement logic
+        if cap == 'contact':
+            if payload.get('contact') == 'open':
+                # Do something
+                await ctx.mqtt.publish_set_thermostat(
+                    'some_thermostat',
+                    desc.params.get('temp', 20.0)
+                )
+        
+        # 4. Persist state if needed
+        state_key = f"rule:{desc.id}:device:{device_id}:state"
+        await ctx.redis.set(state_key, payload.get('contact'))
+```
+
+### Step 2: Register in RULE_IMPLEMENTATIONS
+
+```python
+# In your rule module (e.g., my_custom_rule.py)
+RULE_IMPLEMENTATIONS = {
+    'my_custom@1.0': MyCustomRule,
+}
+```
+
+### Step 3: Configure in rules.yaml
+
+```yaml
+rules:
+  - id: my_custom_living_room
+    name: My Custom Rule for Living Room
+    type: my_custom@1.0
+    targets:
+      my_devices:
+        - device_1
+        - device_2
+    params:
+      temp: 22.0
+      duration_secs: 300
+```
+
+## Best Practices
+
+### Idempotency
+
+Rules MUST be idempotent - processing the same event multiple times should be safe:
+
+```python
+# Good: Idempotent
+async def on_event(self, evt, desc, ctx):
+    if evt['payload'].get('contact') == 'open':
+        await ctx.mqtt.publish_set_thermostat('thermo', 16.0)
+
+# Bad: Not idempotent (increments counter)
+async def on_event(self, evt, desc, ctx):
+    counter = await ctx.redis.get('counter') or '0'
+    await ctx.redis.set('counter', str(int(counter) + 1))
+```
+
+### Error Handling
+
+Handle errors gracefully - the engine will catch and log exceptions:
+
+```python
+async def on_event(self, evt, desc, ctx):
+    try:
+        await ctx.mqtt.publish_set_thermostat('thermo', 16.0)
+    except Exception as e:
+        ctx.logger.error(f"Failed to set thermostat: {e}")
+        # Don't raise - let event processing continue
+```
+
+### State Keys
+
+Use consistent naming for Redis keys:
+
+```python
+# Pattern: rule:{rule_id}:{category}:{device_id}:{field}
+state_key = f"rule:{desc.id}:contact:{device_id}:state"
+ts_key = f"rule:{desc.id}:contact:{device_id}:ts"
+prev_key = f"rule:{desc.id}:thermo:{device_id}:previous"
+```
+
+### Logging
+
+Use appropriate log levels:
+
+```python
+ctx.logger.debug("Detailed diagnostic info")
+ctx.logger.info("Normal operation milestones")
+ctx.logger.warning("Unexpected but handled situations")
+ctx.logger.error("Errors that prevent operation")
+```
+
+## Event Structure Reference
+
+### Contact Sensor Event
+
+```python
+{
+    "topic": "home/contact/kontakt_wohnzimmer/state",
+    "type": "state",
+    "cap": "contact",
+    "device_id": "kontakt_wohnzimmer",
+    "payload": {
+        "contact": "open"  # or "closed"
+    },
+    "ts": "2025-11-11T10:30:45.123456"
+}
+```
+
+### Thermostat Event
+
+```python
+{
+    "topic": "home/thermostat/thermostat_wohnzimmer/state",
+    "type": "state",
+    "cap": "thermostat",
+    "device_id": "thermostat_wohnzimmer",
+    "payload": {
+        "target": 21.0,
+        "current": 20.5,
+        "mode": "heat"
+    },
+    "ts": "2025-11-11T10:30:45.123456"
+}
+```
+
+## Testing Rules
+
+Rules can be tested independently of the engine:
+
+```python
+import pytest
+from unittest.mock import AsyncMock, MagicMock
+from packages.my_custom_rule import MyCustomRule
+from packages.rule_interface import RuleDescriptor, RuleContext
+
+@pytest.mark.asyncio
+async def test_my_rule():
+    # Setup
+    rule = MyCustomRule()
+    
+    desc = RuleDescriptor(
+        id="test_rule",
+        type="my_custom@1.0",
+        targets={"my_devices": ["device_1"]},
+        params={"temp": 22.0}
+    )
+    
+    # Mock context
+    ctx = RuleContext(
+        logger=MagicMock(),
+        mqtt_publisher=AsyncMock(),
+        redis_state=AsyncMock(),
+        now_fn=lambda: datetime.now()
+    )
+    
+    # Test event
+    evt = {
+        "device_id": "device_1",
+        "cap": "contact",
+        "payload": {"contact": "open"},
+        "ts": "2025-11-11T10:30:45.123456"
+    }
+    
+    # Execute
+    await rule.on_event(evt, desc, ctx)
+    
+    # Assert
+    ctx.mqtt.publish_set_thermostat.assert_called_once_with('some_thermostat', 22.0)
+```
+
+## Extension Points
+
+The interface is designed to be extended without modifying the engine:
+
+1. **New rule types**: Just implement `Rule` and register in `RULE_IMPLEMENTATIONS`
+2. **New MQTT commands**: Extend `MQTTPublisher` with new methods
+3. **New state backends**: Implement `RedisState` interface with different storage
+4. **Custom context**: Extend `RuleContext` with additional utilities
+
+The engine only depends on the abstract interfaces, not specific implementations.
