  • Perfect. From Japan not China
Perfect. My Dehumidifier works great but the woke programming inside it is terrible. In order for it to do it's job, witch it is quite capable of doing, I have to run it 4 time harder and longer. Now I set it on continuous run and use this controller to turn it on and off. Wow. What a difference. I live in a big 5th wheel in Florida, so I'm constantly fighting the humidity. In the last few days, my dehumidifier has run a heck of a lot less than it runs without the controller. I am actually looking forward to seeing my electric bill this month (-: ... show more

  • Works very well
This device works very well for my purpose of controlling a dessicant dehumidifier. I use this dehumidifier in a large "box" I built to dry the soundboards for the harps I make. Previous to purchasing this controller I used a humidity/temperature controller that one would attach to a wall in your home or office. This previous controller was awful at gauging the relative humidity in the box or a small room. It required that I constantly keep checking its measured RH to that of a separate, small humidity/temperature measuring device that seems to work very well and can be checked and adjusted fairly easily. This new humidity controller is designed very smartly and its measurements of RH seem to correspond very closely with the small measuring device, unlike the previous controller I used. Also very nice is the fact that I can now have this controller OUTSIDE of the box with the soundboard and dessicant dehumidifier. It has a short cable with an AC receptacle that the dehumidifier can be plugged into, but the actual humidity measuring device is attached to the controller via a fairly long cable. I have the humidity measuring device inside the box, and the AC cord for the dessicant dehumidifier comes out of the box to be plugged into the short cable off of this humidity controller. So I can easily check the RH inside the box without having to open up the box (and thereby raise the RH level). And you can adjust the controller to automatically turn on when the RH reaches 1% to 5% above the desired RH level set on the controller. The only thing I do not like about this device is the god AWFUL english instructions! Can the people at the company in China who make this controller please hire someone who can write clear understandable english, PLEASE!! You will eventually make sense of their nearly non-sensical instructions, but it does take awhile. Just so you know, their "differential" RH level means how far above the target RH the actual RH will get before the device turns on. You can set this differential RH level for 1% to 5% over the target RH level. ... show more

  • Works well, simple, no hiccups.
Works beautifully to detect and give an easy reading on humidity in the space it's in. I used it along with a humidifier to achieve precise humidity in an aquarium and it's a beautiful piece of electronic. Pair it all with a digital timer and you've got a hands free fully automated humidifier system for your needs. Get this is you're on the fence. It's exactly what you need. ... show more

  • Controls problem dehumidifiers
I had to purchase this because the Waykar 80 pint humidifier that i purchased works except for the junk humidistat that they use. The piece of junk won't turn off and is running up my electric bill. I contacted the company and they were willing to send me a replacement humidistat and then a replacement unit but the reviews are all poor concerning the humidistat. This was easy to set up and when I connected it to my Trash Waykar humidifier, the sensor read 58 on the display, but the humidifier was showing 73, which explains why the Waykar 80 pint humidifier will Never Turn off. If you own a problem humidifier that won't turn off like I do, then order this and let it control the humidifier versus buying another new one. I took off one star because the instructions sent with this are Not very clear and you need a magnifying glass to read it. Luckily there are videos available on YouTube that show you what each setting means and how to quickly program this controller. ... show more

  • Great produce, great price, great customer support!!
My wife runs 3 egg hatchers and our Inkbird controller makes environmental control for these a breeze. This unit is very easy to program, very accurate and dependable. The alarm system that notifies us when the humidity is outside our set parameters relieves from having to check the hatchers multiple times a day. We use a baby monitor placed near the controller with the receiver in the house, works great to notify us of any issues. After nearly a year of use, one of our controllers stopped functioning. I contacted Inkbird, they responded quickly and sent us a replacement within a couple of days. THANK YOU INKBIRD!! ... show more

  • Great customer service!
I had my Inkbird Humidity Controller in my mushroom monotub for several months and it controlled the humidity very well. One day, while under warranty, it stopped shutting the humidifier off when it passed the desired level. After a few emails to trouble shoot the problem Inkbird sent me a new controller. ... show more

  • Game changer
This has been an absolute game changer in my grow tent. Being able to dial in the environment, has led to MUCH better grows. I can’t begin to explain how much of a change I’ve seen, for the better, in my plants.
