Review on White Lutron Maestro Vacancy Sensor Switch, 5-Amp, Single-Pole/Multi-Location, MS-VPS5M-WH - Improve Energy Efficiency And Comfort Experience by Sandro Pierce

This is a nice device, but not perfect.It has four time-on durations, which are somewhat limited (1, 5, 15 and 30 minutes). I would have liked to have also seen 10 and 60 as options. This setting can be changed with the switch cover on.It can be setup to turn on three different ways: (1) Motion on/lack of motion off; (2) Switch on/lack of motion off; and (3)Motion on if dark/motion off. The last one will apparently learn how dark you want it before it turns on. This setting can only be set with the switch cover off, and on my unit the lights did not flash as indicated in the instructions, so it was hit and miss between the three settings. If setup to work with switch on/lack of motion off, there is some grace period where waiving your hand or otherwise moving will turn it back on. That is nice!You can also adjust sensitivity high/low, but again only with the switch cover off. It does seem very sensitive on high, with it even noting motion in another room bouncing 180 degrees off a tile wall. I haven't tried the low sensitivity.The device is not terribly large, but does require a ground wire connection. Oddly it has two ground wires, which makes it seem sort of amateurish--not sure why they couldn't have connected those two wires internally so the user would only have to connect one, but that is a minor point. The part hidden behind the faceplate is plastic, and in my sample white not brown as shown in the picture. Again minor.Overall I'm very happy with the way the device functions, particularly that it has a grace period to turn back on with motion even if you have it not set to turn on with motion.
