Circling back to the curtain PIR-- it worked out great for my application. In the IQ panel you can adjust sensitivity (low medium high) which works great. It actually ships with a wall bracket that allows you to adjust the beam 5 or 10 degrees so your curtain covers where you need it. It’s a great way to have a motion sensor in a room but still we able to actually use the room. In my case you need to get right up to the window casing to trigger the sensor.
