I just got another 06002m after the first one I got just got stuck on whatever temperature it started with. This one I just got as a replacement now only reads -40 when I take it outdoors where the temperature is below 20. It is communicating fine with a excellent/strong signal with the Smart Hub. I tried all the stuff with new batteries, switching channels, hard reset etc with the same result. Do I return another one? Same issue as https://support.acurite.com/acurite/topics/06002m-temperature-and-humidity-sensor and https://support.acurite.com/acurite/topics/06002-temperature-and-humidity-sensor-with-acurite-access... which I saw no resolution on. Do I return/replace this one too?
