Leviton Humidity Sensor Switch for Bathroom Exhaust Fan, automate Ventilation, air Circulation, Moisture Control, ¼ HP, Single Pole, DHS05-1LW, White

While I'm not a fan of the price point, this switch is great. We installed the switch in the owner's bathroom where the ceiling fan sits just outside of the shower door. Before this sensor, someone (who shall remain unnamed) would take a scorching hot shower and not turn on the fan. Condensation would coat the windows and mirrors, walls would start sweating leaving discolored trails in the paint, and a hero from the adjacent room would have to plunge into the steam cloud to manually activate the fan. And of course, once it was on, it’d run for hours — far longer than needed — simply because no one remembered to turn it off.This switch solved all of that. Installation was simple despite my best efforts to overcomplicate it. Wiring it straight forward and only takes a few minutes (less than 5 minutes, unless your toddler "helps" you by keeping the wire nuts but then melting down when learning they don't get to keep them as toys). The think that took me time was adjusting the humidity threshold for activation and how long the fan stays on — though after some fiddling, I ended up back on the default settings. Honestly, they got it right out of the box. I would have saved 30 minutes had I at least given their defaults a day or two to test run instead of messing with things.One note: keep the printed instructions. You program the unit using button presses and then decode its status via a series of color-coded LED flashes. It’s not difficult, but trying to pull up a support PDF on your phone - the printed instructions are just easier.Still not wild about the price, but I'd begrudgingly pay it again because I feel like the quality is. It consistently fires up before any condensation gathers and I don't have to gasp through any more steam plumes caused by my wif... er... that unnamed culprit's lava showers.

I love this switch more than someone should love a switch. I know, that sounds like hyperbole. Let me explain.Prior to installing this, my bathroom fan switch was on the opposite side of the room from my shower and at an angle where it wasn't in line of sight; as such, I often would remember I needed to turn on the fan only after I had started showering, which either meant a cold, wet walk across the room or skipping the fan altogether. For the times I remembered to start the fan ahead of time, I'd have to either remember to turn it off after the steam had cleared, which could take a while after finishing my shower... Not great.Now, the fan turns on automatically within about a minute of starting my shower, and turns off when the humidity drops below the setpoint. No more having to remember to turn the fan on and off. Installation was not much different than installing a regular light switch.

As an electrician, I tackle a lot of DIY projects around the house. When the exhaust fan in our bathroom gave up the ghost, I figured it was the perfect time to upgrade the old manual switch as well. We use a lot of Leviton products at work, so I knew I was getting a reliable brand.The main issue in our household is that my wife enjoys marathon showers and often forgets to leave the fan on long enough to clear out the humidity. This can lead to problems like mold and mildew. Enter the Leviton DHS05-1LW. This switch automatically activates the fan when it detects humidity, ensuring the bathroom stays dry without anyone having to remember to flip a switch.I was so impressed with its performance that I installed these switches in all three of our bathrooms and the laundry room. Installation was straightforward, and the switch's slim profile fit easily into our existing wall boxes. Plus, it can be installed with or without a neutral wire, adding to its versatility.In summary, the Leviton DHS05-1LW has been a game-changer for our home's ventilation. It's a smart, reliable solution that keeps our bathrooms and laundry room free from excess moisture.

This sensor seems to function as intended and has different operating modes depending on room and type of humidity level (eg. bath fan, continuous air flow, etc). My only knock against this things is it feels really cheap. Like soft cushy plastic cheap. Like others I put this in my kids bathroom because they cant remember to turn the fan on, but I cant imagine this holding up with continuous daily use if it was your only switch. Thankfully I have a dedicated fan switch, which they don’t touch anyways, so this will kick in as needed. Would recommend despite this issue—others work but not well so if you’re going to do the work to install you might as well get something you won’t regret soon later.
