What kind of mister do you have? Why do you have it going off every hour? You can just have it go off three times a day for 2 minutes or so. I don't know what you should do for feedings other than offer lots of food before you leave. Give him some free roaming crickets, about 20 at most before you leave and leave an orange quarter in the cage for the crickets so they don't chew on him. That should give him food for about one to two days and he should be fine for three or 2 days without food.
