[New Generation] Humidity Sensor Switch, Ortis in-Wall Bathroom Fan Automated Control Switch, Air Moisture Detection, Neutral Wire Required, White, 120V/220V

This thing is awesome. My wife and I never turned on the fan when taking showers because we never remembered to. After years of doing this it started causing molding issue's in our bathroom. Installed this in a quick 10 minutes. (If you know how to wire an 110 outlet it is the same) adjusted the setting to turn on and run for how long I wanted it too and at what humidity and we were set. I did have to adjust it a little bit between summer and winter just due to atmospheric humidity changes which with the manual was easy to do. Always keep the manual handy because you won't remember how to make adjustments to settings without it.

The product works exactly as described. It performs reliably and meets expectations without any issues. I’m very satisfied with the quality and overall experience. Based on my experience, the directions are a little tricky, but there is a good video on You Tube . I would definitely recommend

Works great

Not sure if I should rate this 3 or 4 out of 5, because it seems to work well and actually has a display so you can tell what’s going on, but the usability is rather poor even in the simple case of activating the fan after using the toilet.First problem: to turn the fan on manually after taking a dump or whatever, it’s not obvious which button to push. One button is labeled “M”, the other is labeled with up/down arrows, and both buttons are the same size. It should have one large obvious button and one or two smaller ones for anything more complicated than on/off.Figuring out what the on button is might not be a problem for you in your own house (it’s the M), but it won’t make much sense for the average guest toilet user.Second problem is: even if you know it’s the M button, you have to click M once to turn on the display backlight, then click it again to actually turn the fan on. This is unnecessarily awkward and confusing for an on/off switch.Third problem: to configure the thing you also have to click a button once to turn on the backlight then hold M. Holding down M without clicking it first doesn’t work and just results in more unnecessary confusion as to why it won’t give you the config settings.Fourth problem: the configuration settings have a typical “CNC module” format of numbered registers and numeric values. Without a reference chart there’s no way to tell what they are, aside from some where you can guess from the configured values. Yes I realize that there’s not much space on the display, but the display already has some of the etched icons needed to represent some of the setting values, rather than using “1” or “2”, but the design doesn’t make use of these expensively etched icons in the configuration menu. All of the settings should be using these icons and custom etched glyphs like most consumer devices.In short, this looks like it was designed by someone who designs CNC modules who designed it like an industrial CNC module. That would be great if this were on a CNC machine, but it makes no sense for a fan switch in a bathroom where it will be used by the average toilet user.Maybe the original product requirement was for an industrial control that just happens to fit into a gang box and not for a bathroom or kitchen wall switch, so it was designed like an industrial control, but this unfortunately makes it a lot less suitable for residential use. I only bought it because I absolutely needed a display with configuration options and am familiar enough with CNC modules that I can deal with it, but even then it’s still more of a pain than it needs to be.Lastly, this is not a problem with the product but note that in a bathroom it should be installed closer to the ceiling, ideally, to better detect the humidity of hot humid air from showers and sinks. In a normal wall switch position you can lower the threshold where it turns on but isn’t on all the time due to a humid day or other normal conditions.Note that there’s another model with a remote humidity sensor, but that needs batteries that periodically need replacement.Other than those issues it seems to work fine. The only limitation on its programmability is that manual activation is limited to 1 hour, so if you need to leave the fan on longer to remove fumes or something unrelated to humidity then you have to click the thing every hour. There’s no permanent “on” override and no way to configure longer on times.

First off, the instructions are not the best. The install is straightforward and the wiring diagram is sufficient, but the setup menu is plain awful. There are 6 menu settings in the instructions and the actual device has 7 setting options. Since they are just numbers, I have no idea if I have set up the device correctly. If I guessed correctly, then it should shut off when within 6 % humidity. The range of humidity started at 57% and went to 44% while playing with setup. That took about 3-5 minutes so I know the humidity didn't actually change that much. It was a humid feeling in the room and my other gauge showed 58%. I think I finally figured out that one of the settings was duplicated and so I set the humidity offset at +8 %. The other settings like manual run time setting starts at 1 and goes to 60 before returning to 1. The manual shows a 30-180 second adjustable setting. I left it at 45 to try out. Also you do have to press the menu for 3 seconds to save the settings otherwise you have to go through them all again. The M /Manual button does work well to turn off and on the fan. The product page says “NEW GENERATION: We update a critical opition for minimum run time, you can setting for how long the fan runs in auto/manual mode, default time is 1 min (1 min - 60 min)“ (notice they misspelled “option”) There is not any mention of this in the instructions, so I figure this is the extra setting, but I don't know which one it is.The other issue I have is that I replace a single switch which has a standard switch plate cover. This is a rectangle opening and there was no cover included with the switch, so I will have to order a cover that I expected to come with it. If you buy other smart switches, they typically come with a matching cover plate.I’ll update if I ever figure out which setting is which, but they definitely need to update the instructions and provide a better interface.

I am very impressed with this Humidity Sensor Switch. No more guesswork to see and know the humidity in the bathroom. The digital display of the current humidity is very helpful.Installation and the setup was very easy. The flowchart in the enclosed manual is perfect. If you are okay with the default settings, you do not have to do anything; just install and turn the breaker ON.The default RH was 55%, but I changed it to 50%, which is more comfortable for me. So, in my settings, when the RH (humidity) gets to 55%, the fan will automatically turn ON and when it gets down to 45% the fan will turn off.The easiest way to change the parameters is to push the "M" button twice and it will turn ON the fan, then push "M" to turn it OFF. Now push and hold "M" again, and now the setup menu will come ON, starting with 01, which is 55% and it is the default RH% value. Push the "up/down" button to change it. and you will be able to change it from 30% to 80% or anywhere in between with a 5% increase.There are 7 changeable parameters that you can replace as per your likeness.
