Ordered the Honeywell TM005X to track moisture in the crawlspace after having the space sealed. I placed the remote sensor under the house (near the center) and the indoor unit somewhat above the sensor. Has been working great for the past month or so.I'd have some concern if the outside unit was actually outside of the house. As an original test I placed the unit on the open porch in <20 degree weather. The indoor unit lost the signal sometime during the night. I suspect the type of batteries used has some impact on this situation. That's not an issue for me as the crawlspace is conditioned.As always, Amazon's service was A+!
