Hi Ken and thanks for the answer.
the first time I installed the steelgauges, in the weatherflash menu I had enabled "active server", with an interval of 3 seconds. However, after a few hours of operation VWS crashed. So I enabled "server", again for 3 seconds, and the problem was solved.
Now I tried to follow your advice: I enabled only "active server", with an interval of 10 seconds. Something has improved, the problem of "station offline" are no longer resubmitted for more than a quarter of an hour, but then it is inexorably reappeared.
The version 2.1.0, instead, iworks indefinitely, only sometimes the "text file corrupted" message appears, but the cycle continues to operate.
Now the question is: why version 2.1.0 does it work?
