You can try 0x00001:BOOL[1]. The Modbus register coil status addresses range from 00001 to 09999, and I just checked, the regular expression matching in the code follows the same pattern. ADDRESS_SHORT_PATTERN FIXED_DIGIT_MODBUS_PATTERN

Aaaaaa ... now I understand the isssue ... yeah ... I first thought this was related to the "Register 1 = address 0 on the wire" problem ... but yeah ... the address is not in the valid format. I guess it's just missing some zeroes ;-)
