no data : vp2 anemo Options

[helmer]

Hi all,

Since about 5 years my anemo is running OK. Just last december my console and my envoy didn't receive any data from it. Both the direction fan and the cups where spinning/turning, but no data received.
I checked connection on the station, and renewed extention connectors.
Then about 2 weeks later, during short heavy rain with lightning and gusts of wind, my atation received data again.
Then last friday ... again ... no data . I fear the most for my anemo.
My station only received what seems to be wind direction fluctuations, but no wind speed.
Who's got experience which a seemingly dying anemo .
