And here I am again with questions!

So I found a kind of Temperature gauge in my house and I’m using it to keep check the temps of the new cage. So I was wonder, what are the best temps for a chameleon?
The new cage is currently at 74 degrees F at the bottom and 78 at the top of the cage. (This drops to like high 60s at night). This temp is without the lighting, Nachitos current basking spot is like 84 degrees F in her current cage. So if this is to hot, what would be the best way to cool it. (Note the temp might fluctuate thought the day due to the sun shining though my windows more in the afternoon)
What do you guys think about the temps?
Edit: also I currently can’t seem to get humidity much above 30ish degrees F durning the day and at night. How do you think I might be able to increase that at night?
