Biggest waste of money!

I have two tall tanks ( both 36" )
One has red eyed tree frogs (A. callidryas) the other set up for black eyed tree frogs (A. moreletii).

I have come to the conclusion that hygrometers are the biggest waste of money compared to any other supply that is a necessity.
The equipment is the same in both tanks.
The equipment for measuring humidity seems to collect, I suppose it is because of them being inaccurate!

Example--Tank one ( red eyes )

a zilla wire/ probe device...that has been stuck on 99% for about 3 months ! obviously broken ? but then, one never knows !!!!!!!!
an exo-terra wire/probe device
an open ( indoor/outdoor) wire/probe device from Home Depot
and a NEW one.......yes.......... a 4th
A "wireless weather station" .............desperate RIGHT!

Here is what they all read:
The Mist King sprayed at 7AM.
The open probe device and the NEW wireless weather station are both protected from a direct spray from the MK.

The basement / outside the enclosures is 56%

the exo reads- 76%
the zilla reads- 69%
the HD reads- 65%
and
my new wireless weather station - reads 86%


How frustrating is this !!!!!!!!!!!!

So my inclination is to lower the humidity for my red eyes, for the time being, anyway !
Winter is an entirely different mess of readings !!
