Hi @jayeff . It's not delay issue, since it happens many minutes (maybe hours) after I've entered my apartment.
It's like the unlock mechanism is not being triggered. So I have to keep trying pushing in different ways and strengths until it gives any signal of "life". Once or twice I had to force the open with a knife on the door's slit where the dead bolt is.
For some reason, when closing, the door is able to lock (dead bolt) but the system is not activated, so it's not able to trigger the unlocking system.
