I bought the humidifier controller for my grow tent where I am growing gourmet mushrooms. It has an outlet (Work1) for the humidifier and one (Work2) for either an exhaust fan or a dehumidifier. However, when the humidity reached the cut off point, the fan wouldnt kick in to lower the humidity, which just kept climbing until it reached the limit (99%) and then the alarm went off. I contacted Inkbird and when I explained the problem—without hesitation—they said they would sent me a new one, which I got today. Good customer service is almost obsolete these days, so I really appreciate Inkbird! Thanks. I hope this one works ok.

I use this to control the humidifier in my grow tent. It works perfectly for that application. You just need to make sure the sensor (hygrometer) is in the right spot. (and theres water in the humidifier, of course)

Does not work the best to measure humidity unless calibrated somewhat often & for sure not as user-friendly as advertised. It helps to watch youtube videos and third-party materials to figure out usage.

This device has worked very well in keeping the relative humidity level constant in a room where I keep my guitars (acoustic and electric). There is a good YouTube video that made the setup process easy (enter IHC-200 in the YouTube search). Im using this controller with the AquaOasis 2.2L humidifier. With this device, I am keeping my relative humidity at 50% +/- 3%. In seasons where the natural humidity level is already high, I dont have to fill the humidifier tank for days. It has my enthusiastic recommendation.

Despite the odd brand name and surprisingly low price, this thing is excellent. If youre not a techie you might find the settings menu bewildering. I have HVAC background so cryptic menus like this are old hat. Accurate remote humidity sensor. Makes a slight but noticeable whine like in its power supply. Power cord is pretty thin so its a bit worrisome plugging in a high-current device.

The instruction manual is very hard to understand, obviously written by people for whom English is a second language. But, once you get past that, it works beautifully and seems very accurate. The display is very easy to read.

I purchased my InkBird IHC-200 February 2022. I have multiple InkBird products and count on them for accuracy and reliability. My IHC-200 had a fatal malfunction, this was past the warranty period. InkBird did not even blink twice before sending me a replacement. Customer service is a priority for me when I decide to purchase from a company. I will continue to do business with InkBird without any reservations. Thanks InkBird.

Save money and purchase this inkbird product. Inexpensive, works great, east to set up and compared to other manufacturers, they are fairly priced.

Definitely a game changer! Used for legal medical grow tent environment control along with humidifier/exhaust fan & it beats hanging wet towels every couple hours. 3 stars on accuracy because im not sure. I also use a simple digital temp/humidity gauge along with sensor supplied with this controller & theres variances between the two but I take into account the differences between the 2 devices. Which one is more accurate? I make it work. When things are leveled out they are pretty close.

I keep an acoustic instrument room humidified with an industrial humidifier plumbed in. This was an excellent solution to having the fan in the humidifier run all the time. Great product ! Wish you could run another appliance off of it at the same time
