Also those temperature/humidity gadgets are as good as useless as they are very inaccurate had few they all had different values next to each other and ditched them all.

i don't have the ability to change her enclosure at the moment, but i have a heat lamp (non light) and my humidifier running right next to the tank. it's about 70% humidity and 78 degrees F (25.5 C). it's fairly dry and cold where i am in NY.

Heat lamps cause dehydration...Ive never used a heat lamp for a tarantula in nearly 40 years. Heat the room...60-70 degrees is fine. Dont worry about the humidity....humidity levels are from where their ancestors were found. They can adapt to our humidity levels here in the U.S.
P.S. a deli cup is less then $.10

Great suggestions @Konstantin and is correct, humidity needs do not need to have any micromanagement or overthinking, just simply keep a small bottle cap of water and lightly dampen the substrate. How I keep my T's warm is simply putting an electric oscillating heater in the room and have it set at 74 F. The rest of my house can stay cool with my Tarantula room at a constant 74 F and I live in central NJ.

I agree with @Arachnoclown about heated lamps, bad news for T's, just room temps are fine.
