Ink Bird IHC200

I noticed when running my Humidifier I noticed my tents RH wouldn't be stable. I'd be a 50% in the morning and 39% afternoon. A fellow member linked the Ink Bird IHC200 in the discord chat, I am glad I purchased it.

Installation was confusing to say the least. A couple things I messed up was;

WORK 1 is Humidifier ONLY and WORK 2 is Dehumidifier ONLY. 

When setting up the switch you have to HOLD Set to lock in your set value. 

I didn't need to calibrate it, seems to match up with the monitor I already have in the tent.
