It is quite normal feature that if a door is open more than x minute then do an action, but only we have at the moment is immediately open or open more than 1 minute. I am looking forward for the addition of this feature and support this thread.

I've also requested this feature Check this Feature request

Any news on this topic?

My feature request has been blocked, so I supposed that discussion would proceed here

If you use the sensor to control KE100, there is a feature for open window detection.

The request was just to set the time for the push notification, and not to trigger something with the smart actions... that is also welcome, but i think the original request is still not fulfilled.
