Notify HomeMatic when a window is open.

blueprint:
  name: Heizkoerpertemperatur bei geoeffnetem Verschluss absenken
  description:
    An automation blueprint that reduces the set temperature of your climate
    device or group if a contact sensor is open for more than the preset wait time.
    It uses the Homematic window sensor channel to set the temperature to the "Open-window
    temperature" set in the device configuration. You should set the "Mode for temperature
    fall detection" to Inactive to avoid conflicts. It waits until the contact is closed
    again in order to restore the climate entity temperature. It has an optional blocking
    entity to prevent the automation running unnecessarily, for example during the
    Summer season.
