Iworked well for about 3 months in an 80% humidity enviroment. It then began giving eratic measurements or sticking on a false temp untill i jiggled probe wire. Which was not ideal when counting on humidity kicking back on when away. It barely worked when i stored it away 5 months. I just gotit back out to use it and it gave me the error screen after 1 day. Kind of dissapointed. I was thinking if i treated it well it would do job for long time with maybe needing to replace sensor once a year. I guess the relay stopss working after repeated on offs. I hope im still under warranty period but im unsure of length .

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.

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

This is a simple On/Off controller with adjustable hysteresis. Accurate readings and control require a minimum amount of air moving across the sensor. The Relative Humidity will always fluctuate around the set point with this type of controller ( Or any controller). With some tweaking of this controllers settings and the output level of the humidifier. I can get +- %5 RH. Good enough for most mushroom cultivation fruiting tents. It is a good value compared to a $200 PID controller that cannot do much better.

I have bought several IHC-200 controllers for use in a greenhouse. They work well, except one had a problem with the display. I contacted customer service, got a response within 24 hours asking for a video to demonstrate the problem. I sent the video and the next day they said they would ship a replacement. The true test of a company is how they respond when something goes wrong, and Im satisfied with their response in my case.

We started using this humidity controller in our snake’s tank in January 2022. After about five months of daily use, it started malfunctioning — continuing to power the connected humidifier even after it had detected shut-off humidity levels. The result was a tank full of fog at 90+% humidity (30% above target range). We were able to reset the device, but it malfunctioned again after several days. This cycle repeated a couple times, which became an obvious health hazard for our snake. We had no idea when it would stop working properly, and that increased the chance she would develop a respiratory infection. So we reached out to Inkbird support, and eventually they sent us a replacement. The replacement device worked properly for about the same length of time before malfunctioning in the same way. We reached out to Inkbird a second time, and they encouraged us to buy the product again, since the 1-year warranty had expired. All of this is just to say that manufacturing quality here is spotty at best, and you shouldn’t expect any one controller to last more than about 6 months. It works pretty well when it’s working, but the product is junk at its core.

Added this for my grow tent, easy to use and really helped control my humidity by automatically toggling my humidifier and dehumidifier. As someone mentioned make sure your units have a toggle switch not push button power or they device will not turn on when power is switched onto it. For the price its hard to beat, it was 3% off from my goove humidity monitor but you can adjust the calibration on the controller so it matches exactly what my other monitor says. Not sure which is correct but 3% isnt a deal breaker, the important this is you can adjust the controller to match any other humidity monitors you might already own.

Does anyone know how to switch from work2 to work 1? Im losing my mind trying to figure it out.
