# 🌡️ Smart Thermostat Controller Blueprint

An intelligent Home Assistant automation that manages your heating based on multiple conditions for optimal comfort and energy efficiency.

## ✨ Features

### 🪟 Window/Door Detection
Automatically turns off heating when windows or doors are opened, preventing energy waste. Configurable delay to avoid false triggers.

### 🌤️ 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

### 🏖️ 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).

### 🔄 Multi-Thermostat Sync
Manual adjustment of any thermostat instantly syncs all others to the same temperature, giving you quick override control.

### 🎯 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

## 🛠️ 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

## 📊 Smart Logging

All mode changes are logged to your Home Assistant logbook for easy monitoring and debugging.

# Acknowledgement and background

I tried different Home Assistant add-ons and integrations, but wasn't really satisfied in controlling room temperature in our house. The heating is based on central heating and radiators with different Zigbee-based termostats.

This blueprint for HA was initially inspired by [ha-smarter-thermostat by muratcesmecioglu](https://github.com/muratcesmecioglu/ha-smarter-thermostat), but deviated through extending to also include an away calendar and a manual overwrite mode to allow manual inputs on the thermostats. Logic coding was assisted by claude.ai.
