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.

These work great when your (wired) switch location cannot see the entire room for which you want to automate the lighting.So far, I've used one in a bedroom with angled entry (switch can see only about one third of the room) and one in the garage. Both are mounted above doorways and sense as soon as you pass through the door. Due to the inswing door on the bedroom, we mounted the sensor in line with the door panel (roughly above the hinges) so only the thickness of the door can block the sensing.Battery is included (CR 123A lithium 3V), as are mounting screws.The battery door doubles as a mounting plate, so it's easy to take the sensor down to change settings.Settings on the back include:time (5, 15, or 30 minutes);sensitivity (high, medium, or low activity required to turn/keep the lights on); andauto-on (enable = occupancy sensor or disable = vacancy sensor). All are set by pressing and/or holding buttons and watching status LEDs on the back.It also has buttons on top for light (toggle on/off) and test (the sensor, not the load, flashes when motion is detected).These sensors communicate wirelessly with compatible Lutron switches (e.g., Lutron MRF2-6ANS-WH Maestro Wireless 6 Amp Multi-location Switch, White -- Amazon product B002SY5HMM -- http://www.amazon.com/gp/product/B002SY5HMM/ ) and the pairing process is fast and simple (carry the sensor over to the switch for greatest convenience). While installing the ceiling-mounted Lutron sensor, we tested the range with the sensor about 50 feet from the switch and they worked without fail (with clear line of sight). Not sure what the range might be with obstructions like walls in between. My wall-mounted sensors (the model I'm reviewing) are within 20-25 feet of the corresponding switches and work fine.These are not cheap, but if typical motion-sensor switches don't fit your application (e.g. can't see the space), then these are a wonderful solution.
