ha-smart-thermostat-control

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, but deviated through extending to also include an away calendar and a manual overwrite mode to allow manual inputs on the thermostats.

🌡️ 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

Manual adjustments (highest priority) Windows/doors open → heating OFF Too warm outside → heating OFF Away mode → reduced temperature 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.
