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.

This humidity controller is OK when it functions as intended. Programming is relatively easy and it seems consistent. However after a few weeks I started getting an ER- code. The device emits a loud tone when this happens and ceases to function. After inspecting the device I found nothing amiss with the setup. After an hour or so the unit clicked back on and resumed normal function. This pattern continued and increased in regularity resulting in semi-regular humidity dips and as a result the plants suffered greatly. This behavior became more and more regular as use of the device continued. Eventually the ER- would not clear and the device was removed from use. Upon further inspection and disassembly of the sensor whip it appears as though one of the leads was not seated all of the way into the connector, resulting a short and the ER code. After reseating the lead the device was tested and functioned per normal. That sensor whip contains a strain reduction loop which the sensor cable wraps around prior to reaching the sensor. While this is a nice feature... it results in the leads being almost taught within the sensor enclosure and likely was the root of the failure I experienced.

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 functions well, but I use it to sense humidity in a terrarium and pump in a humidifier when it dips too low. The plants I grow love high humidity, so its not an issue if the humidity reaches 100%. Unfortunately the device has a panic attack when this happens, and will sound an alarm any time it gets that high. (The minimum setting for the alarm maxes out at 100%, with no option to have it off). There is no way to tell this device not to sound the alarm, and its annoying as hell to have this thing occasionally go off after misting the tank.

Runs an original Hydrofogger Humidifier for a 16 x 35 greenhouse.

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 was battling high humidity in my flower tent so I got this little gem. Super simple to operate, and it has controlled the humidity within 10% of the set point. If the plants are happy I’m happy, and the plants are happy.

Works great

This works like a charm, a little difficult to figure out at first but rereading the instructions helps!

Easy to set up. Had to make sure the humidifier is not touch control, because if the controller switches it off, you have to make sure the humidifier automatically switches back on. Sounds obvious, but those touch control off/on humidifiers wont work well with this type of controller.
