Hello I also have this driver in operation on my Raspberry, but still with version 3.9.2 In the beginning, the weather station and the Raspberry always did the same thing. It tried up to 5 times to connect, but since I shared a fixed IP address in my network with the Raspberry, that's over. I have no idea if that was it but precisely because of these things I don't dare to update my Raspberry with Python 3 and weewx to version 4.
