VeSync integration: LV600s not showing up

I recently added the VeSync to my HA instance, but only one of my two humidifiers show up. My OasisMist 4.5qt shows up and works great; my LV600s does not sync at all despite it being listed as supported. I’ve already restarted HA, deleted and reinstalled my VeSync integration, and restarted HA again. Anyone have any insight into why the LV600s isn’t showing up?
