Update: the wind direction is being reported but not the wind speed...will a reset at the sensor cure this??? Thanks again...
I've had that happen to me. The LED lights, wind direction transmits but speed doesn't.
Put a toothpick behind your ear, get the ladder out, climb the roof, loosen the 8 screws , reset with the toothpick and then have someone on the ground press and hold channel. If that doesn't work, repeat and give the person on the ground a toothpick so they can reset the console right after you reset the transmitter.
If there is snow on the roof, throw a rope over the roof to the other side and have someone belay while you slip your way up.
It's been a once every month or two exercise for me the past six years.
It looks like the VP2 I got this summer is going to let me retire from this exercise....
