Product review (2 stars): Good idea, but remote sensor is eating batteries like candy
Would love it, except the remote sensor seems to chew through batteries on a 1 to 2-week basis. Remote is under the house in a crawlspace, directly under the indoor receiver, separated by 4 feet of air and 2 inches of plywood. I thought the first quick battery death was because I used old batteries. Second set, I checked before loading and they were green all the way. Noticed after a couple of weeks that the numbers on the "outside" sensor hadn't changed in quite a while, then noticed the remote sensor icon on the main receiver was showing "no bars". Replaced batteries again, with known good new batteries and this time noted the date. Noticed today (10 days later) that the numbers hadn't changed for the remote sensor for a couple of days, then looked more closely and saw the remote display on the main receiver at zero bars again. Peeked under the house at the remote and sure enough, no red LED blinking to indicate the unit is transmitting. Maybe I have a defective remote sensor? Don't see a way to contact seller (Amazon) for this order. Will put in new batteries again tomorrow and see if the 8 to 14 day life span continues.
Update: 3 months later, remote sensor is even more "hungry" for batteries. Now a fresh pair lasts 3-4 days. Called Acu-Rite number on the warranty info. Started at #15 in queue, finally got a rep after 40 minutes on hold. Will be shipping a replacement remote unit under warranty.
