[Chancery Hotel] Touchless sensor buttons open doors unintentionally
This was recorded at the Chancery Hotel in Dublin, where certain rooms have these sensor-based controls for all the amenities in inside: the lights, air conditioning, and even the bathroom door. While they lack the tactile feel of the real buttons, most of them are still ok to use. But the ones for the bathroom door are not.
The problem is that these are not capacitive touch sensors that react to the physical touch. Instead, they seem to work more like proximity sensors, activated when you bring your hand close enough to the button. In fact, I've seen it respond to my hand been 2-3 cm away from the sensor, which makes it easy to accidentally activate it by simply passing near it. This happened to me at least once, and I've heard the same complaint from several other guests staying at the hotel.
This is particularly annoying in the situation when you're wet, exiting from the shower, and accidentally open the door by simply walking too close to the wall. It brings the cold air from the room inside, and exposes you naked, which might not be exactly what you want if you're sharing a room with someone.
On top of that, the door itself has no handle or groove to be used as a backup option for manually opening it. So if the sensor breaks or electricity interruption, the door becomes unsuable.
