  Hi!
  
  The Aranet4 has an accurate T/RH sensor built in that shows RH with a +/-3% RH accuracy: https://assets.aranet.com/documents/Aranet_Datasheet_TDSPC0H3_Aranet4_HOME_Z5oT3mT.pdf

  See if the other gadgets are as accurate as aranet or not.
  Also, in high humidity areas (>80% RH) the screen of the aranet might get damaged and long-term exposure ,especially condensing atmosphere might temporarily increase the relative humidity reading above the actual value. To rectify this, it’s advisable to dry the sensor in an environment with low relative humidity
