Lutron LRF2-OWLB-P-WH Radio Powr Savr Wireless Wall-Mounted Occupancy/Vacancy Sensor, White

I love it. This RF unit is the first one I bought. I have bought other motion sensors from Lutron in the past. This one Easily paired with MRF2-6CL-WH. Replaced a regular switch with the MRF2-6CL and paired them. it works great! Wife can't yell at me for leaving the closet lights on. Default settings worked fine for me.Update: It's been more that two years and it is still going strong. Have not changed the batteries yet. I hope i remember how to configure if I need to when i change the battery. Really great product!

I bought this item along with the Lutron Maestro Wireless Switch, MRF2-6ANS-WH. The bottom line is that they work great. When I initially installed the items, I could not get the wireless sensor to "pair" with the wireless switch. I called Lutron customer service. In the course of a 30-minute phone call, we determined that I had made a mistake in wiring the switch. Correcting that mistake fixed the problem. The sensor is now inside a walk-in closet while the switch is outside. When I walk into the closet, the lights come on after a delay of maybe 1 second. Shortly after I leave (the time can be set to 5, 15, or 30 minutes) the lights go out. If you buy this combination, read the instructions very carefully. If you are familiar with electrical devices, you might (as I did) mistake the blue screw for a green screw and attempt to use it for grounding. That would be incorrect and would prevent the device from working. My kudoes to Lutron's Customer Support for patiently working with me to solve the problem.

Solves the problem of needing more than one vacancy or occupancy sensor in an area with automatic lighting.We have stair lights that remain on until turned off, so it's okay to have an occupancy sensor for the secondary / additional stairway lighting. Everybody always leaves the lights on in the stairway! The switches are correctly located at each end of a long wrap-around stairway, but neither one can "see" the middle of the stairway.This is as easy to install as a Casèta remote - a couple of button presses and it's in the system. Simple buttons on the unit itself control operational modes and delay times. The occupancy minimum time as longer than other Lutron occupancy switches at a full five minutes, however it makes it very unlikely that a hallway will go dark when somebody is inside.No wiring or computer required as long as there is a Maestro master switch or dimmer or controller in the circuit. If you order a Maestro dimmer for a 3-way installation, be sure that you look up and get a companion dimmer designated as compatible. The 3-way / multi-location master and "companion" must be listed as compatible on the Lutron web site or you'll go nuts wondering why it doesn't work.This is too expensive for what is inside of it, and a bit annoying that it doesn't double as an alarm motion sensor, but it is old-tech and likely to work for some time ahead.Instructions mention that there is a bridge to tie all the old Maestro switching units to Homekit and similar systems. We use these older systems in stand-alone to have an alternative means of control in case one system fails, as well as to avoid expensive upgrade cycles as IOT evolves. Bad enough that new phones are pushing $1,500 bucks and lasting a year or two -- no way that we want to do that with every switch in our house at some point.I love having lights come on without having to touch the switch, as well as the convenience of them going off when not in-use. Since we use LED lights throughout our house, dimmers and automatic switches are unlikely to pay for themselves in electrical costs. The LEDs make a huge difference in light quality and cost. The automation of lighting does cut the electrical bill even more, but the main feature is convenience.

I am using this sensor mounted about 6 feet off the ground in a small room, where one end of the room has a narrow opening that goes down a long (30 foot) hallway. The sensor was mounted on the wall opposite the hallway opening, and it was aimed straight down the long hall. My goal was to be able to use a single sensor to see movement in the room as well as seeing people at the far end of the hall. I am happy to say that it does just that. Being wireless is the biggest advantage though: it made it trivial to place it where it needed to be for best motion-sensing performance without having to worry about where to run any wires. Highly recommended. I am using it in conjunction with aLutron Maestro MRF2-6CL-WH - Wireless Dimmer.

a bit cheaply built for the money, instructions are TERRIBLE but once I got it set up it works great
