Thanks Tom, that driver seems to work OK.
Though now I faced another issue, it looks like the WXT510 is emitting NMEA
strings which the driver is not capable of yet ;(

The hex string decodes to an apparent NMEA message of

When reconfiguring weewx for NMEA, I get this;

So I think I need to take the WXT510 down from the roof and reconfigure it
for serial data using the service port. It does need cleaning anyway :)
