    Be forewarned you need a deep electrical box to install one of these without difficulty. I had a deep double box and installed this switch next to a GFCI with ease. Sensor turns on fan at 50% humidity on default setting and I confirmed that through testing. The light switch and fan switch buttons work very well and have withstood constant use for the past 8 months with no issues. This combo switch may be pricey but it is well worth the price in my opinion.

    worked exactly as it state. Programing was easy. Fan will come on automatically with humidity or if you turn it on manually it will only turn off if the humidity is below the programmed level or the timmer will take over and shut it down after the programmed time. So you can used for smell and humidity.

    Had a manual 2-switch for fan and light, but people had the habit of either forgetting to turn on fan during shower or leaving the fan on all day. This item solved the headache.
    Now the fan auto-starts based on humidity and turns itself off later on. Perfect !
    You can set the run times for use as a smell fan, various modes or complete override if you wish, quite configurable. All the config is done through the two front buttons. Easy to do, but definitely keep the manual (or grab a pdf and store on phone/pc).
    No wire nuts are included, but are required if you are upgrading from a screw terminated switch to this one. Neutral wire is not required , but it can be connected if you have one.
    My only beef is that the switch isn't very tactile. When you walk into the room and want to switch the light on, you have to seek out the button. Maybe I'll get used to the 'feel' of it eventually.

    5.0 out of 5 stars Easy to install and works well
    Reviewed in the United States on October 15, 2024
    Verified Purchase
    Replaced a dual fan/light switch with this. I chose this because I wanted a humidity controlled fan but the light needed to be manual on/off only (over the tub). Lots of other humidity fan/light switches are also occupancy sensing for the light. This one was easy to install, and the default settings on the humidity control and time settings are perfect. (Rapid increase over 50% humidity triggers fan, will run for 20 mins). It will also re-sense after 20 mins and run the fan an additional 10 mins if needed. Pushing the fan button will run the fan for 20 mins, which is needed for households with people who would turn it on and let run for hours and hours without a clue and also don't pay the heat bill.

    Reviewed in the United States on September 14, 2024
    Verified Purchase
    I needed to make room in the switch box in my bathroom for another light, so I used this to combine the fan control along with the built in light. The sensor has been working flawlessly. It accurately detects humidity levels and turns the fan on at the default setting of around 65%. I've had no issues with false triggering, and the sensor has been a reliable addition to my home.

    Unfortunately, mine died. It was installed in mid Nov 24 and lasted until mid March 25. It worked great but now seems completely dead. Power is going to it but the led is not illuminated and neither switch is work. I am very disappointed.

    Reviewed in the United States on December 24, 2023
    Verified Purchase
    My son kept forgetting to run the fan when he showered so I ordered this switch. It comes on by itself and doesn't take that long to kick on once I have the shower going. Maybe a minute or so.

    If you turn the fan on manually, the fan will shut off by itself after 20 minute which is nice. A lot of times I'll run the fan then leave for work and don't have to worry about it being on all day. You can change the setting on it to be less sensitive and the amount of time the fan runs but I was fine with the way it came programmed. I was worried it wouldn't be that great especially for how much it cost but it works a lot better than expected

    Update 4/2025
    My first switch stopped working for the fan part of it so I called the customer service and they sent me another one right away. Their custoer service is domestic which is nice. The second switch has been running flawlessly since I've installed it. Glad they stand behind their product.

    They even had me mail the old switch in so they could see why it failed. They paid the postage and I got the new switch before I got the return postange e mail so getting the new one was not contingent on sending the old one in.

    Verified Purchase
    I installed these in our bathrooms. 1 has stopped working after just a few weeks. They are nice for making sure fans are run when they should be but unfortunate there may be reliability issues. Install/removal also takes a little longer switching back and forth from post style switches to this switch with 5 stranded wires and wire nuts. I may try again as the auto on/off is worth it to me.
