About two years ago, my daughter gave us a La Crosse Indoor / Outdoor
weather station (Model 8300) with an outdoor sensor/transmitter unit.
It worked perfectly until recently...


I have bought several *wireless* indoor/outdoor thermometers...

They ALL are a piece of crap! None of them worked very long. One worked
a year and a half, but I don't consider that long. And not a battery
problem.

Anyway I switched to the "wired" type and those have been working fine
for several years. The only problem with these is you need to run a wire
from the inside unit to the outside sensor.
