I completely agree with this being an option. If it’s set to Away, it makes sense to require a pin in case someone snuck in a window. Also remember, many times, people have motion sensors, and if they snuck in a window, the motion trigger will activate an alarm anyway. But as Carverofchoice so eloquently put it, if its set to Home, everyone inside the home in theory is allowed to be there already, and should be able to disarm without the need to enter a pin.
Many people (especially the elderly) won’t bother arming the system if they have to go through hoops just to disarm it when they’re already home and just need to go out to the porch for a few seconds. It’s easy enough to get someone to just hit Disarm when they leave and Home when they come in… But if they have to hit Disarm-PIN-Checkmark everytime even when at home… They won’t bother using the system at all… That’s the problem I’ve run into, and I tend to feel the same way.
I remember when it actually did work like this, and in September 2021, an update changed it to the current method of always entering a pin. I recalled posting about this years ago when the change was made, and I just found that link: Pin required to disarm - #20 by CTU.CNY
