My blueprint is working with the homematic ip local addon for the CCU. With this you are able to bind any binary_sensor to an homematic ip thermostat.
blueprint:
name: Window Open, Notify HomeMatic IP Local CCU
description:
An automation blueprint that reduces the set temperature of your climate
device or group if a window 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 window 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.

Hello,
should i connect this blueprint with the Homematic Heating group, or the wall thermostat in this heating group?
If set to heating group. Temp goes down, but no window open icon on the wall thermostat.
If set to wall thermostat, the icon is shown, but temp does not go down.
Also is there a way to prevent manual increase the temp after the window was opened?
I use HomeMatic Groups and it works fine - the temperature is changed and the open window icon appears on the thermostat. If you look on the CCU does the setting change there?
I recomment to connect the blueprint to the heating group.
The window open symbol appears on then on all devices in this group. (thermostat and wall thermostat)
You have to be patient. Homematic IP took some time to sent the commands to all devices. So try to open the window an wait 2 min. Then look in the CCU if the command has been sent so all devices without any error.
Thank you for the blueprint, works for me with aqara zigbee sensors.
Is it possible to set a delay after the window is closed, so the thermostat won’t set itself back after a few seconds?
My homematic ip thermostat usually waits a few minutes (because without window sensor, he probably has a fixed time when the “window open” has triggered)
I would like to set it to something like 3-4 Minutes, because after i ventilate my flat i would like to wait for the thermostat to adjust to the new room temperature, rather than setting itself back to like 22°C after he got 4°C cold air.
Yes, after examining the code (im not really good with programming) i changed the 5 seconds manually, but your change with the slider works great! thank you.
After using this now for about 3 months i sometimes get a thermostat stuck in “window open” state.
Did you or somebody else also experience this?
It happens really rarely and i think it happens because of the internal “window_state open” within the thermostat itself, triggered by a slow drop in temperature (opening a window).
When the window is closed and the blueprint state change is about to happen while the thermostat internal state-change is about to trigger “window open”, it probably causes this problem. Usually it should revert back in about 10 minutes as if you had no window sensors, but it does not.
I had it a few times, only locally switching from auto to manual and back will resolve the issue (hope my explanation was somewhat understandable).
Hey… I’m using your blueprint to switch a thermostat with a shelly blu window sensor. my ccu is Raspberrymatic on HomeAssistant.
If the window is left open and temperature reduced to 12C, the heating profile overwrites the temperature as soon, as the setting in the profile activates a new temperature.
Just in case anyone still searches for a solution: I enhanced this blueprint to not only set the WINDOW state but also to switch the Thermostat into manual mode (and back to automatic mode, if window is closed). Here is the code:

It uses the Homematic window sensor channel to set the temperature to the "Open-window

fall detection" to Inactive to avoid conflicts. It waits until the window is closed
again in order to restore the climate entity temperature after 5 seconds. It has an optional blocking
entity to prevent the automation running unnecessarily, for example during the
Summer season.
