Doesn’t sound like a python2/3 issue but rather a unit group assignment issue. To use the WeeWX formatting and unit conversion each WeeWX field needs to be assigned to to a unit group, eg outTemp is assigned to group_temperature so WeeWX knows that outTemp is a temperature and not a pressure. Unit/formatting flows from that unit group assignment. Looking at your weewx.conf you appear to be using a number of fields that are not in standard unit group assignments. That’s perfectly fine, but you then need to make sure you manually assign those unit groups. This can be done in a number of ways, sometimes it is done with a few lines of code in user/extensions.py or it can be done with some code in a driver or a service (for an example of what I am talking about see Assigning a unit group <http://weewx.com/docs/customizing.htm#Assigning_a_unit_group> in the Customization Guide). It should not be done by modifying weewx/units.py. I have no idea how the klimalog driver handles this, but I could certainly see that if it was to be done manually it could easily be lost if re-installing.
