on a cursory check, I believe you didn't initialize the SHT library on Wire1. Could you change the call of `sht.init()` to `sht.init(Wire1)` and try again?

could you print the complete output? `sht.init()` should fail if the sensor is not detected ("init(): failed"), before readSample(). It should have either printed an error before (defaulting to `Wire`)...
