Bought this to keep my plant cabinet a stable humidity. However, and this may be common sense to some but not to me lol, make sure your humidifier/dehumidifier does not need to be manually turned on (like a button pushed) because it’ll turn off but it won’t turn back on when it needs to. Knob humidifiers should work with it a-ok

Works great

Keeps the tent right where I need it. I have two of them, and they just work.

It works great! Watch YouTube to set it up.

Excellant - Works as advertised. Im using it to control my humidifier in a 10x30 room. Works Great.

For years Ive been disgruntled at purchased de-humidifiers and their lousy humidity control. The sensors in these products are sloppy at best and often fail over time. The key to this controllers effectiveness is the very accurate sensor itself, the rest is just common sense digital control. The available options and settings for controlling the dehumidifier are top shelf! This also works with humidifiers so am looking forward to doing some testing this winter. I FINALLY know exactly what the humidity level is in my basement and rest assured my power consumption to maintain my desired humidity is minimized. (you can even calibrate this controller if you have a known good dry bulb kit or similar) Yes, the set-up is somewhat confusing, but if you have a basic understanding of humidity and hysteresis settings, its a breeze, and easily adjustable at any time you desire. For the price, this is an amazing control, and I would highly recommend it to anyone wanting better humidity control in any environment. Ive had it running for a month now 24/7 with no problems.

This product works well overall. The audible alarm quit working after the first couple of weeks, but it wasnt a big deal... I didnt but it for its alarm function. I was also concerned that the instructions say that the contacts may fuse/melt at the end of its life but they dont give any information as to how many on/off cycles the unit is designed to do before the end of its life. Otherwise, Im very happy with it. The instructions were a little hard to understand but we got them figured out.

After a couple months I get “ERR” on the screen. It’s probably something that I did so idk

I bought this for some plants I am growing in a small greenhouse tent. I need very high humidity 95% or so. I connected this to two humidifiers (targeting different sections of my greenhouse tent). It works awesomely

Just recieved the humidity controller to help regulate the rh in my mini greenhouse. As expected the device works excellent and Im very happy with the purchase.
