Area-Based Open Windows and Doors Sensor

Blueprints Exchange
,
1

This blueprint will help you create a sensor that returns the count of open windows based on selected Areas. The entity IDs and Areas where there are open windows are available as attributes.

Features:

  • Can track both windows and/or doors.
  • Multiple Areas can be used. If no Area is provided, the sensor will cover all Areas.
  • Specific windows and/or doors can be excluded.


Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.

blueprint:
  name: Open Doors or Windows
  description: |
    The sensor's state returns a count of the number of open Doors and/or Windows. 
    Lists of their Entity ID's and the Areas with open windows are provided as attributes.

Template Blueprints are currently (2025.06) only available through YAML configuration. You can find more details about how to use them at:

HA Docs - Templates - Using Blueprints

Once you have installed the blueprint, use the following examples to help set up your own sensors in your configuration files.
