Review on 🌬️ In-Wall Humidity Sensor & Fan Control: Leviton IPHS5-1LW Decora, 3A, Single Pole, White by Andre Tenk

I was researching available humidity switches and settled on the Leviton based on performance and price. I am satisfied with my purchase.1. Great timer that can be set to 10 min, 20 min, 30 min and 45 min. The fan will run for the set time and turn off, or you can turn it off manually at any time.2. The humidity setpoint can be set to Off. or any range from 20 to 80% humidity, as well as the "Air Cycle" mode. When set to Off, it ignores the humidity setpoint and starts when excessive humidity is detected. I'm not sure if this means that it detects the current humidity average and only turns on when it exceeds that average. I bet about 40%. Air Cycle runs the fan for the timer once per hour, which is handy when you need constant airflow regardless of humidity.3. sensitivity levels. Off, Lo, Honey and Hello. Off is only for Air Cycle mode as it works on a timer and not humidity. The Lo Med and Hi sensitivity levels have two uses. Lo is for smaller spaces but also the least sensitive, and so on for Med and Hi. My bathroom is approximately 6ft x 6ft. I set a timer to 10 minutes, set the humidity to around 40% and set the sensitivity to Lo. I live in Colorado so our humidity is usually around 30%. So far this setup works great, I turn on the shower and after about 2 minutes the fan comes on and then off at about the same time when I get out. It may turn on again if the humidity is still too high, then turn off after another 10 minutes. I've never had a fan turn on accidentally when I'm not taking a shower. This is exactly what I wanted to prevent from mold and from touching the switch with my hand. My fan and light are separate units, but this switch can also be connected to a fan and light combination. The only problem would be using a timer as it also turns off the light. Regardless, you need a neutral wire (usually sheathed in white) to return the current. This switch doesn't work properly without a neutral wire, it stays on all the time without it because the current has nowhere to go back. Most switches these days require neutral, which is good for safety. If your home was built in the 90's or newer, you should have a neutral wire in the junction boxes, even if your current switch doesn't use it. A 14 gauge copper wire connection can simply be added to this. Edit: I changed the sensitivity level to medium. There is a vent just below the switch and I've found that the switch on Lo doesn't work when my oven fan is running. Update in a few weeks: The switch now won't turn on the fan regardless of the humidity settings. My wife said it still works for her but she didn't even want that switch. So I'm lowering my rating from 5 stars to 3 because it was for me and my peace of mind. At least the timer still works fine. Update, still a few weeks later: It's been working fine since my last update, so I'm changing my rating from 3 to 4 stars. Just in case I won't take it back for 5 stars.
