Product review (2 stars): Disappointed: Indoor humidity only
Disappointed to learn that only the indoor humidity is measured - not the outdoor humidity. The item description implies that both indoor and outdoor humidity levels are measured and dismayed. Otherwise, it looks like a nice unit but without the outdoor humidity measured I'm not interested. I have another Thermopro product which I'm very satisfied with so if you're okay with not measuring the outdoor humidity level then this looks like a good item.
