-# 🌡️ Smart Thermostat Controller Blueprint
+#That is a solid, clean, and well-structured blueprint! Based on this final working version, here is the instructional Readme, focusing on setup and the automation's logic flow.
 
-An intelligent Home Assistant automation that manages your heating based on multiple conditions for optimal comfort and energy efficiency.
+***
+
+# 🏡 Smart Thermostat Controller Blueprint
+
+**Author:** Andreas Gammelgaard Damsbo
+
+This Home Assistant blueprint provides advanced control over your smart thermostats, combining schedule-based heating with external factors like outside temperature (Winter Mode), window/door states, and calendar-based Away/Holiday modes. This version is designed for flexibility, using an **Input Number Helper** to control the day temperature dynamically.
+
+---
 
 ## ✨ Features
 
-### 🪟 Window/Door Detection
-Automatically turns off heating when windows or doors are opened, preventing energy waste. Configurable delay to avoid false triggers.
+* **Schedule Control:** Sets Day or Night temperature based on a **Schedule Helper** entity.
+* **Dynamic Day Temp:** Uses an **Input Number Helper** for Day Temperature, allowing easy adjustments via the UI.
+* **Winter Mode:** Heating is disabled entirely if the **Outdoor Temperature** remains above a defined threshold.
+* **Window/Door Safety:** Turns off heating instantly if any selected window or door sensor is open for a defined duration.
+* **Away/Holiday Mode:** Uses a **Calendar Entity** to set a lower Away temperature when you are traveling.
+* **Pre-Return Heating:** Starts heating up before your scheduled return time (using a negative offset).
 
-### 🌤️ Weather-Based Control
-Monitors outdoor temperature and disables heating when it's warm enough outside. Includes adjustable winter mode threshold and delay settings.
+---
 
-### 📅 Schedule-Based Temperature Control
-Uses a schedule helper or calendar to set different temperatures for:
-- **☀️ Day Mode** - Higher comfort temperature during active hours
-- **🌙 Night Mode** - Lower temperature for sleeping or away periods
+## ⚙️ Prerequisites & Setup
 
-### 🏖️ Holiday/Away Mode
-Integrates with a calendar to automatically reduce heating when you're away. Smart pre-heating starts before you return home (configurable offset).
+Before using this blueprint, you must ensure the following helpers are set up in Home Assistant:
 
-### 🔄 Multi-Thermostat Sync
-Manual adjustment of any thermostat instantly syncs all others to the same temperature, giving you quick override control.
+### 1. Required Helpers
 
-### 🎯 Priority-Based Logic
-1. Manual adjustments (highest priority)
-2. Windows/doors open → heating OFF
-3. Too warm outside → heating OFF
-4. Away mode → reduced temperature
-5. Day/night schedule → comfort temperatures
+| Helper Type | Purpose | Setup Notes |
+| :--- | :--- | :--- |
+| **Schedule Helper** | Defines the time slots for Day (On) and Night (Off) heating. | Go to Settings > Devices & Services > **Helpers** > Add Helper > **Schedule**. |
+| **Input Number Helper** | Stores the value for the **Day Time Temperature Target**. | Go to Settings > Devices & Services > **Helpers** > Add Helper > **Number**. Set min/max values to match your thermostat range (e.g., 10 to 30). |
+| **Outdoor Temperature Sensor** | Entity to read the current outside temperature (required for Winter Mode). | This is usually provided by your weather integration. |
+| **Window/Door Sensor Group** | Entity or group of entities that are `on` when open. | Multiple sensors can be selected directly in the blueprint, or you can create a Group helper first. |
+| **Away Calendar Entity** | Used for Holiday or extended Away periods (e.g., Google Calendar, iCal). | This entity must report `on` when an event is active. |
 
-## 🛠️ Requirements
+---
 
-- Window/door sensor(s) (binary_sensor)
-- Outdoor temperature sensor
-- Climate entity (thermostat)
-- Schedule helper OR calendar for day/night timing
-- Calendar for away/holiday periods
+## 📝 Blueprint Configuration (Inputs)
 
-## 📊 Smart Logging
+When creating a new automation from this blueprint, you will be prompted for the following:
 
-All mode changes are logged to your Home Assistant logbook for easy monitoring and debugging.
+### Core Entities
+| Input | Description |
+| :--- | :--- |
+| **Thermostat** | Select all `climate` entities you want this automation to control (can be multiple). |
+| **Schedule Helper** | The `schedule` helper defining day/night times. |
+| **Day Time Temperature Input Number** | The **`input_number`** helper that controls the target temperature during scheduled Day hours. |
+| **Night Time Temperature Target** | Static temperature target for scheduled Night hours. |
+| **Away Temperature Target** | Static temperature target for when the Away Calendar is active. |
+
+### Winter Mode Logic
+| Input | Description |
+| :--- | :--- |
+| **Outdoor Temperature Sensor** | The sensor providing the current outdoor temperature. |
+| **Winter Mode Threshold** | If the outdoor temperature is **below** this value, heating is enabled. (Default: **16°C**). |
+| **Winter Mode Delay** | Time the outdoor temp must stay *above* the threshold before heating is turned **OFF**. (Default: **30 minutes**). |
+
+### Window/Door Logic
+| Input | Description |
+| :--- | :--- |
+| **Window / Door Sensor Group** | Select one or more `binary_sensor` entities. Heating stops if any are open. |
+| **Window / Door Sensor Delay** | Time a window must be **open** before the automation turns heating **OFF**. (Default: **5 seconds**). |
+
+### Away Mode Logic
+| Input | Description |
+| :--- | :--- |
+| **Holiday or Away Calendar** | The `calendar` entity indicating away/holiday status (`on` when active). |
+| **Return Offset** | Time before the calendar event **ends** to start heating. Use a **negative value** (e.g., **-120** minutes starts heating 2 hours before you return). |
+
+---
+
+## 🧠 Automation Logic Flow
+
+The automation uses a priority-based `choose` block to determine the required heating action. It executes the action for the **first condition that is met**.
+
+| Priority | Condition Check | Resulting Action |
+| :--- | :--- | :--- |
+| **1** | **Window/Door Open?** | **OFF** - Turn heating off immediately. |
+| **2** | **Too Warm Outside?** | **OFF** - Turn heating off if the outdoor temp is above the Winter Mode threshold. |
+| **3** | **Away/Holiday Active?** | **Away Temp** - Set target to the static Away Temperature. *(Requires Winter Mode active and windows closed).* |
+| **4** | **Day Time Active?** | **Day Temp** - Set target to the value from the **Input Number Helper**. *(Requires Winter Mode active and windows closed).* |
+| **5** | **Night Time Active?** | **Night Temp** - Set target to the static Night Temperature. *(Requires Winter Mode active and windows closed).* |
+| **Default** | *(No high-priority conditions met)* | **OFF** - Turn heating off (e.g., if the schedule is inactive but Winter Mode is not met). |
