InkbirdIHC-200 Dual Relays Digital Humidity Controller Humidistat for Humidifier Dehumidifier

I bought two or these items , they have been working for over a year non stop, no issues so far

Nice product although not easy to set up

A game changer to keep humidity (rh) at a constant stable. Really easy to use & set up an actual game changer & great value. Keeps temps & or humidity bang on very accurate. Happy with this product very much.

Nice piece of kit, but I’d say the hydro meter is a little off, still works well though if you factor it this in!

I thought I'd wait a couple of months to write a review for this product as I wanted to properly test it.I rigged the Inkbird controller up to an extractor fan situated inside of my fish shed. I have 30 aquariums and high humidity levels were always a concern. I had tried adding air vents, then smaller dehumidifiers and fans, but nothing brought the humidity to acceptable levels. So I bought an extractor fan and had it plugged into a timer switch and set it to go on and off at 15-minute intervals. This worked well, but the temperature fluctuated too much (I heat the shed, not individual aquariums). I knew there must be a better way of doing this. I did a bit of research and the Inkbird controller kept popping up. I had to try it and it has been amazing. There was a wee bit of trial and error programming the device, but eventually, I got it to do what I wanted. It turns on at 70% humidity and turns off at 50% humidity. and my shed temperature stays around 27 degrees Celcius. I'm happy with this product and it has been a great investment. I'd recommend it to anyone who has a fish shed or reptile room.

EXCELLENT CONTROL OF HUMIDITY IN GREENHOUSE.

Nice piece of kit, highly configurable for various usage scenarios and customer service is prompt and helpful.

I bought one of these controllers, having bought one before and found that one to be working, so I needed an additional one for another project.It arrived on Saturday and so I plugged it in to try it out. It seemed to be working correctly but after removing the humidifying mechanism, I found that even after two days, the readings were showing far higher than I'd expect. Initially it was stuck over 90%. It even suggested that my living room was at over 80% humidity.As I couldn't get these readings to lower, I contacted Inkbird support to report the problem.They suggested that I "dry the wire and probe with a blower(sic), test the air humidity, check to see if the readings are right".This prompted me to ask the question 'If I have to dry the wire and probe with a blower, what’s the basis for assuming its accuracy? At what point in the future will I know that the readings are inaccurate without verifying it with another device?'They responded with "Perhaps you can compare it to other hygrometer for testing".So there you have it: They admit that their product is in fact so unreliable that you need another device to test its accuracy (which could be out by a massive amount) and you'll be expected to know when to test it, too. Somehow, I'm supposed to know when it's going wrong so that I can test it, otherwise it'll destroy my projects.
