Reason is simple, yes the door is unlocked but if I walk away to put something in the dustbin outside I don’t lock the door. If I walk back I want to open the door that’s where the button is for. The door is unlocked but I want to open it. There is just a knob on the outside and it can be twisted.
That’s why I still use the Danalock app. It used to work on my Domoticz solution before I start using the Homey.
I see no real security issues in opening an unlocked door by pressing the open button. It is one of the main reasons it is in the Danalock app as well. The only ‘security’ issue I see is accidental pressing the open button while you are not at home but that could also happen in the current implementation. Pressing the unlock button while you are away and the door is locked.
I am already using a Virtual device and that is the workaround but would be a nice add on that’s all.
