Review on 🍄 Inkbird IHC200 Humidity Controller: Optimize Mushroom Greenhouse with Dual Stage Humidifier Dehumidifier - New Version! by Ryan Bowers

Bought this thing to control the gentlemen in the greenhouse which are powered by a 110V solenoid valve. Well out of the box it seemed great, I installed it, installed the sensor where I wanted it, and Set the desired humidity level of 50%. He worked during the day and then the moisture level he felt was wrong. This morning gentlemen worked God knows how long and the reading was 43%. The other two sensors I had showed 100% and the entire greenhouse was filled with water. There is a function to calibrate + or - the displayed value and I've tried it a couple of times. It looks like this value is not stored in memory and then pops up everywhere within a few hours. Totally defeats its purpose if I have to keep checking to make sure it's being read correctly. For me it would be fine if the relative humidity was constantly deviating by 5 or 6 - but it would be constantly deviating by 30 or 40% RH. I would advise you not to trust this at all if you have a sensitive application. I'll try to get it back and get a Jaybird humidistat.
