Welcome Jules,
This is only my second year at beekeeping so afraid I can't help much. I would think that the bees, themselves, control the humidity in the hive at the level they desire. There is a reason they do things their way. Maybe consider creating an environment for them that cause a little condensation inside the hive such as less insulation on top so that the cold air from the outside hits the warm air inside, leaning the hive so that the condensation runs to the front wall instead of dripping down over the bees.
