A hygrometer on the outside, digital or not, might as well be in the other room. Get one and place it inside once calibrated.
Re-Season humidor and then focus on the cigars. Doing both at the same time will only lead to more headaches. You dont say what you are using for humidification, if you're not using beads GET SOME. Heartfelt or Shilala's.
Once the humidor is holding steady for a few days you can SLOWLY start to work on the cigars. It will take a month or two to get them stable at around 60%. Only after smoking them will you know if they are alright for consumption.
The main thing is to take the process slowly.
