Brand: Panasonic Residential Automatic Switch (with sensor wiring device) 2-wire/3-way wiring compatible / LED only Detection-triggered continuous operation time: Approximately 10 seconds to 30 minutes, adjustable Brightness sensor and manual switch included Compatible loads: Compatible LED lighting and incandescent lamps I was using this as a motion sensor for kitchen lighting. I used it for about a year. I rarely used the switch on top. This is because I had already switched to a Hue switch. The features of this sensor are: 1. The lighting time can be set to a maximum of 30 minutes. This is helpful when doing standing work in the kitchen. If movement is detected within the time, the timer resets to zero, which is obvious. 2. The sensor's detection angle can be adjusted to some extent. This is helpful because it prevents the sensor from reacting unnecessarily even if someone moves in the nearby living room. I am selling this sensor because it is no longer needed due to renovations. If anyone needs it, please consider purchasing it.
