This thing is amazing!!! I love everything about it!!! My plants love it too! I noticed when it’s sensor faced the wall, it thinks the room is more humid than it is. But when you put it in the middle of the room, it’s more accurate. I set it to 70% humidity and my room is pretty foggy. But definitely humid haha! Worth it!! It’ll only turn back on once it reaches 5% lower than your set humidity.
