My Model #06004 5-in-1 weather sensor constantly transmits a humidity reading of 99%. I did a reset as per instructions posted here. After 5 days inside next to the 06016RM unit, the humidity reading was still 99%. I hesitate to purchase a new 06004 unit for $90 as the purchase price of the complete set was only $120. Apparently this is a common failure. Does AcuRite make good on these units beyond the warranty period or should I look elsewhere ?
