See also this post. Once upon a time, the import java.lang.math worked for me and Biginteger bitwise.
Then it didn’t work - don’t know why, but substitute import java.math.BigInteger sorted it out.

Bitwise operations in a modbus register

Well, this is odd. Despite previous testing, the rule given above no longer works for me - the import does not work… Not sure which version of what changed, but here I give an alternative that works. Note, the rule needs a change, as well as the import. import java.math.BigInteger // we need this for testBit rule "update hvac register" when Member of HvacBits received command then var register = BigInteger.valueOf(0) // we need BigInteger type to use testBit if ( Reg_Image.state …
