I have one, I use it to control c02 in one of my flowering rooms. I have not hooked up anything else to it yet, I have the mini split remote for it but haven't hooked it up yet as my mini kinda just stays where I need it anyways. I also dont have internet in my building yet. So really I'm not getting many of the functions it's designed for, I basically just got it now instead of another c02 controller, I'll use more options later on.
