I love electronic gadgets and live in an older home with one small bathroom, but multiple electrical wall switches--one for the above vanity light fixture, one for the ceiling fan, one to activate the ceiling heater and lastly one to turn on the main ceiling light fixture. When I would have guests over, they often would get confused about which switch to turn on and in addition to this it seemed a nuissance to constantly turn the switch on and off in a room that gets used throughout the day or evening. So, I bought and installed this Lutron Maestro dimmer, but initially bought one from Lowe's that cost more (close to $50) and it looked virtually the same as dimmer pictured so I assumed it was the same. That is when I realized that Lutron makes 2 versions of this dimmer--an "Occupancy" and "Vacancy." The main difference is that the vacancy turns off automatically, but will NOT turn on automatically. To have this electronic dimmer turn on automatically, you must specifically buy the "Occupancy" model which neither Lowe's nor Home Depot stocks in its Southern California stores--they only carry the Vacancy version. The "Occupancy" version seems to be mainly available online. In any case, this dimmer works really well and for middle-of-the-night bathroom visits. It has a great feature that incrementally/gradually dims up and dims down the light--which is much easier on the eyes then going from a pitch black room to full brightness
My only complaints are:
#1 Because of its digital technology, the Maestro dimmer seems to ONLY work with less energy efficient incandescent light bulbs. I tried instead using a specialty CFL spiral bulb that was specifically designed to work with dimmer circuits/switches, but that type of flourescent CFL bulb is ONLY for traditional manual electric dimmers--not new technology digital dimmers such as the Maestro--which was a disappointment. Therefore, be aware beforehand that you unfortunately cannot use newer, energy efficient "dimmable" CFL or LED bulbs with this dimmer because they will not work. For shorter term use in bathrooms, garages, closets, etc., however, since the dimmer theoretically will not be on for extended time periods, that difference in wattage/energy consumption should not be that significant toward your utility bill, but still would be better if the dimmer would accept those newer, "green friendly" type, low wattage light bulbs.
#2 It would be great if Lutron can eventually create an additional photocell version of this dimmer, because keep in mind that every time someone walks into the room during the daytime, this dimmer will still activate anyway because it electronically detects your body heat entering the room (or that of your pets). In my particular bathroom installation that is not that big of a deal since theoretically the bathroom is only used for brief time intervals, but in a main room of a home--a kitchen, living room or den--this will likely mean the switch would have to manually be turned off each and every day during daytime hours--which could become a nuissance.
#3 I am not that tech savvy and to those who are similar, the instructions can be somewhat complicated and require several readings for complete understanding. Again, the default factory settings will likely be fine for most people, but for example, if you want to alter the auto off time period from 5 to 15 minutes, adjusting the timer can take a little time and patience.
#4 It would also be great if Lutron could integrate a nightlight-type feature into the front of the switch--though I suppose if the dimmer is set auto-on, then having such a guide light feature is not that critical. But for times if the dimmer is in manual use mode, having an indicator light would be nice in a dark room. (There are miniscule green LED indicator lights that always flash when the dimmer is activated, but I do not think they serve well as a dark room guide/nightlight because they are not bright enough).
