+# KNX Cover Control with Inverted Position Feedback (Home Assistant Blueprint)
 
 This Home Assistant blueprint allows you to control a `cover` entity via KNX group addresses  
-(Up/Down and Stop) and sends an inverted position feedback in percent back to KNX.
+(Up/Down and Stop) and sends an **inverted position feedback in percent** back to KNX.
+
+It is designed for installations where KNX uses:
+- `0 % = fully open`
+- `100 % = fully closed`
+
+while Home Assistant uses:
+- `0 % = fully closed`
+- `100 % = fully open`
+
+So the feedback is automatically inverted:
+- HA `0 %`  → KNX `100 %`
+- HA `50 %` → KNX `50 %`
+- HA `100 %` → KNX `0 %`
+
+The feedback is sent whenever the cover position changes, no matter if the movement was
+triggered from KNX or directly from Home Assistant.
+
+---
+
+## Features
+
+- Control a Home Assistant cover via:
+  - KNX Up/Down group address (1 bit, DPT 1.xxx)
+  - KNX Stop group address (1 bit, DPT 1.xxx)
+- Send inverted position feedback to KNX:
+  - KNX position feedback group address (DPT 5.001, Percent 0…100)
+- Optional inversion of Up/Down direction
+- Optional feedback cooldown to reduce KNX bus traffic
+- Fully configurable via UI (no YAML editing needed after import)
+
+---
+
+## Installation
+
+Copy the blueprint file into:
+
+'''/config/blueprints/automation/bahmcloud/'''
+
+Example filename:
+
+'''knx_cover_with_inverted_feedback.yaml'''
+
+Then restart Home Assistant or reload automations.
+
+---
+
+## Create an Automation
+
+1. Go to  
+   **Settings → Automations & Scenes → Blueprints**
+2. Select **"KNX Cover Control + Inverted Position Feedback (%)"**
+3. Click **Create automation**
+4. Fill in:
+   - Cover entity  
+   - KNX group address Up/Down  
+   - KNX group address Stop  
+   - KNX position feedback (%) group address  
+   - (Optional) Invert Up/Down direction  
+   - (Optional) Feedback cooldown  
+
+Create one automation per cover.

+## KNX Group Address Mapping (ETS)
+
+| Function              | KNX Object Type | DPT      |
+|----------------------|-----------------|----------|
+| Up / Down            | 1 Bit           | DPT 1.xxx |
+| Stop / Step          | 1 Bit           | DPT 1.xxx |
+| Position Feedback %  | 1 Byte          | DPT 5.001 |
+
+---
+
+## Example Logic
+
+| Home Assistant | KNX Feedback |
+|---------------|-------------|
+| 0 % (closed)  | 100 %       |
+| 25 %          | 75 %        |
+| 50 %          | 50 %        |
+| 75 %          | 25 %        |
+| 100 % (open)  | 0 %         |
+
+---
+
+## Requirements
+
+- Home Assistant ≥ 2026.1
+- KNX integration configured and working
+- Cover entity with `current_position` attribute
+
+---
+
+## Use Case
+
+Perfect for KNX wall switches and touch panels that show the blind position in percent
+and expect:
+> 0 % = open, 100 % = closed  
+
+while Home Assistant internally works the opposite way.
