Incorrect. It detects motion. waving my hands under the spout doesn’t do anything no matter how long. Waving the hand 1.5 in further makes it work only while I shake my hands. It stops immediately after I love my hands. I need to have one hand further activating the sensor while I rinse the other then swap.
It’s was pretty easy (failed once because I didn’t quite follow the steps, you really need to count your button presses and screen taps, any extra press and it’s a do over)
Still mildly infuriating.
