Recently I had noticed my outdoor sensor was not showing the correct temperature when it dropped below -20C. Also the humidity has been stuck at 99% since the summer. So I brought it inside and changed the batteries. Then nothing was transmitting from the outdoor sensor. After the 14th time the inside display finally hooked up. The Wind and temp seem to work but the humidity is still stuck at 99%. I have a 3 in 1 with colour display. Sensor is a 3N1TXCA2.
