Works perfect. No more "I forgot to turn the fan on" crap. I set it very sensitive just to be safe. Stupid long hot showers they take. No more sauna in here. Recommend.

Bought this as the apartment I rented had a combined switch for light and fan. Not ideal. Often times I don’t need the fan if I’m just brushing my teeth or something else. So I took it upon myself to find something automated because I hate having to remember to turn off the fan, or stumble into a dark room at night to use the toilet.It’s worked 100% the way I expected it to. With the door open it’s a little overzealous with the motion sensing, and over time the humidity sensor has been a bit hit or miss. However, there’s always the button and the built-in timer which is really the point. I can activate it by breathing on it very hard, but the ceiling in my bathroom is pretty tall so all of the steam goes up way higher than the wall switches. Not a fault of the unit but worth knowing.I also use the bathroom for drying my clothes the rest of the way after a partial run in the dryer, and it works well for that too to keep humidity down. Really appreciate this purchase from a simplicity/convenience/energy perspective. 100% would do it again!

I use this in a shed to power an exhaust fan, and a separate light. I have it set to turn on the fan when the moisture level reaches 65. It works great. My shed houses my water pressure tank, filtration system, and my washer/dryer. No more dripping sweat on hot days from the water pressure tank and filtration system.Just keep in mind that using a standard electrical box will have this unit protruding quite a bit.

I purchased this combination switch for my kids bathroom since seem to always forget to turn the light off and never turn the fan on or open the window. The switch works well most of the time. The motion sensor works perfectly, but the fan doesn’t always come on when the humidity is high. I can tell the sense is working since the light on the fan button turns red, but so will occasionally check it and find that the fan didn’t turn on even though the light is red.The instructions are very basic but adequate. There are separate wires for the fan and light input supplies. I assume that means you can have them supplied by different circuits but I don’t know which line supplies the sensor circuits, I would think that the fan supply would power the humidity sensor and the light circuit supplies the motion sensor but that is very unlikely. I will have to try it with the second switch I purchased.It was easy to put in. It requires a neutral wire and a separate switch leg for the fan and the light.It isn’t to big, about the same size as a newer slim GFCI or half as deep as an older GFCI.It does not include a cover but does come with 5 orange wire nuts.

I really love this trend of sellers lately to write whatever they want in their descriptions, say things are included when they're not, or put product pictures that don't match what you get.Yes, when I say "love", I do mean hate.Seriously. In the pictures for this product it clearly has a frame that shows the product with a wall plate, a white face cover, a light almond face cover, and a black face cover. The text reads "Interchangeable Face Covers and Wall Plate Included". What did I receive? Just the switch in a box with a white face cover. No alternate face covers, no wall plate. I contacted them and they informed me:"Unfortunately they were not in your package because the interchangeable face plates have been discontinued."Then why haven't the product photos been updated????To their credit, they DID send me the alternate face covers... but if they hadn't, I would have been left with a white switch in a room with almond switches. And what about the wall plate? If the pictures say you're going to get "X" for your money, you can kind of expect buyers to be a little ticked off when they don't get what they should clearly have every right to expect to get. Commerce 101... yes?On to the review...INSTALLATION - Oof. This is not your basic single pole light switch so don't expect it to fit in a handy box, 'kay? For me, I took the wall plate off and discovered... a handy box. Of course I didn't check before ordering, what fun would that be? Luckily, getting the old box out wasn't very hard in this situation because they had used smallish nails to hold the box in and I'm a buff lad. Total meat mittens here that pulled those nails right out with some needle nose pliers. Hoo hah!I had one of these laying around: https://amzn.to/2U5zbgc, which would allow me to fit this switch in the single gang space while having room to fit all the wiring off to the side. A deeper work box would have also sufficed, but I was doing this long after the stores closed so I grabbed what I had on hand. Otherwise, wiring was dead simple and the included guide made it easy to identify what should be connected to what. For the non-initiated, note that although the instructions don't explicitly show that the neutrals all get tied together, they do in fact get grouped in one big nut.FUNCTION - This switch controls the light right over the shower and a 195CFM speed controlled fan that has an inlet in the shower stall. The motion detector appears to be very sensitive but this is a small 2nd bathroom so you are only a few feet from it any point and the door opens right next to it. This works great for us because the shower light works splendidly as dim lighting for the whole bathroom and it kicks on as soon as you walk in or open the door. A "fade up" on like some of my other digital switches have would have been nice, though.Setting the timer for the light & fan is very straight forward, the instructions lay it out well, and you have options for 5, 20 or 30 minutes. Being able to set it in 5 minute increments up to maybe 45 minutes would have been great, but us lowly consumers will have to settle for the 3 options they provide. If you have children who, like mine, have a tendency to take stoopidly long showers... well, you can set this to a limit that kindly reminds them that the shower nazi will be turning the water off any second now and you better get rinsed off... In my case, I set it to 30 minutes which means the light and the fan turn off automatically after 30 minutes. Generous, Obergruppenführer, very generous of you...Setting Humidity detection is also straight forward and although they indicate the range is 45-80% and that you also have 3 options there, they don't tell you specifically what the humidity sensitivity is at for each. Just Low, Medium, or High. We can assume that Low is 45% and High is 80%, but knowing what level the Medium setting is would be helpful. Also, the language used in the instructions is a bit counterintuitive: It says Setting 3 is "High humidity sensitivity (requires high humidity to trigger)". 'High Sensitivity' would usually indicate that something is very sensitive, meaning it would require LESS humidity to trigger. Writers... amiright? Whatever, at least they provided more words to clarify even if doesn't quite make sense...Instructions for setting the motion detector, however, are even more nebulous. The instructions read "Press and hold both light and fan buttons for 10 seconds, the green LED indicator will come on solid. This setting allows users to switch back and forth between Occupancy and Vacancy Mode." Great! Except... how do you actually switch between the modes??? Unlike with programming the timer & humidity settings, the specific programming for Occupancy/Vacancy are not to be found. Though they clearly describe what & how functions work in each mode, the actually programming part is left a mystery for the user... Does holding the two buttons accomplish the toggling? I guess we can assume, but the instructions here pretty sparse compared to the instructions for the other functions. For me, didn't really matter as I wanted the default setting of Occupancy Mode.As far as how well the humidity sensor works... I'm not sure, really. Seems like it's working fine. For an initial test, I breathed on the switch and it indicated a blood alcohol level of .09% and then promptly asked me for my keys. Hmmm... handy, but a bit disturbing, too. Seriously though, I breathed on it and the fan kicked on. Cool. I still tell my daughter to manually turn it on before taking a shower and NOT to turn it off. The first time she did that, I actually heard it kick back on after she left the bathroom so I adjusted the speed controller (separate unit that came with the fan) for the exhaust fan to run a little higher to keep up with what the shower was putting out and I haven't heard it have to kick back on again after a shower. FYI, I left the humidity sensing at the default "Medium" setting."5 Stars" for cool product that is (so far) working as described, minus 2 stars for not including the plate & face covers, plus 1 star for sending me the face covers quickly afterwards = 3 stars overall...I guess that's a thumbs up.
