[feat] - Let open window sensor adjust climate to pre-defined temperature

[Andrecall]

Hello,

Currently if "Window Opening" feature is enabled and the opening sensor is "true", climate will be turned off. Which works fine until I doesn't want to turn off the climate completely, but rather set up some lower temperature when a window is opened and go back to the original temperature when this windows is closed. This feature is quite standard for hardware smart thermostats, i.e. Homematic.

Could we get something similar here?

Thanks!
