+# 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
